Posted by WS Hampshire, Inc. on | Comments Off on Quality Cast Nylon Sheaves From WS Hampshire
Nylon is a durable thermoplastic that offers exceptional strength and versatility. This material is an excellent alternative to metal for custom nylon sheaves and heavy equipment sheaves. Not only are they strong and resist wear and tear, nylon sheaves reduce wear on ropes and wires in a pulley system, for less maintenance and a longer useful life. Here we’ll look at how nylon and metal compare for sheave applications and some of the advantages cast nylon offers.
Cast Nylon vs. Metal Sheaves
Traditional sheaves are often made from steel or aluminum alloys; however, in many applications, cast nylon non-metallic sheaves are just as functional, with these additional benefits:
Corrosion Resistance. Nylon has excellent saltwater and rust corrosion resistance, making it a durable choice for many outdoor and marine applications.
Durability. Nylon’s modulus of elasticity results in minimal deflection under load, which reduces the stress on wire ropes and extends their lifespan.
Lightweight. Cast nylon pulley sheaves weigh a fraction of steel ones and nearly half the weight of aluminum, which means they make industrial and heavy pulley systems lighter and easier to handle and maintain.
Key Applications in Heavy Equipment
With high tensile and compressive strength, cast nylon sheaves can be used for many heavy equipment applications including:
Forklifts and Telehandlers. Reduces wear and improves maneuverability on mechanical systems.
Hoists and Cranes. The lightweight nature of these components reduces the overall load on structural elements of lifts and increases the lifting capacity.
Marine Equipment. High resistance to saltwater corrosion helps extend the service life.
Benefits of Cast Nylon Sheaves
Cast nylon material has a number of benefits for reducing overall weight of components and pulley systems, especially where frequent manual operation is involved. Nylon sheaves are durable in exposed conditions, and can help prolong the useful life of wire rope and cable.
Lighter Weight for Easier Handling
Enhanced Safety. Lighter components allow for easier maintenance and installation.
Increased Load Capacity. Lower sheave weight affords a higher payload, particularly in boom point applications.
Weather Resistance and Corrosion
Increased Longevity. Compared to metal sheaves, the non-corrosive properties of cast nylon sheaves offer lasting longevity.
Reduced Maintenance. Eliminates the need for frequent rust inspections or application of protective coatings.
Extended Wire Rope and Sheave Life
Lower Operational Costs. Requires fewer maintenance interventions and less frequent replacements.
Prolonged Wire Rope Lifespan. High compressive strength results in a reduced cushioning effect and less contact pressure, which decreases wear on the internal rope.

Choosing the Right Material and Design
Originally developed by DuPont in 1935, nylon, or polyamide, has come a long way since its initial use in parachutes and stockings. Common types of nylon include type 6/6 for extrusion and type 6, which can be extruded or cast. Nylon materials have a combination of favorable qualities that make it a good choice for applications in challenging environments, including a high strength-to-weight ratio, corrosion resistance, and general toughness.
Material Grades for Load and Speed
Unmodified cast nylon, is also a durable and strong material, suitable for general applications, offering exceptional hardness and high strength.
Because nylon components are cast by mixing two separate streams of liquid that react, it is possible to incorporate additives that enhance its performance. One common option is molybdenum disulfide-filled nylon, sometimes called “moly.” The addition of molybdenum disulfide enhances nylon’s load-bearing strength and wear resistance.

Posted by WS Hampshire, Inc. on | Comments Off on Acetal Copolymer vs. Delrin: Why Two Types?
Acetal polymers are used in a variety of applications from bushings and gears to rollers and gaskets. They are valued for their exceptional mechanical properties, dimensional stability, and low coefficient of friction, which is why they are used for a wide range of applications. Two primary variants are acetal copolymer and acetal homopolymer, also known as Delrin. While they are often used interchangeably with success, there are some important differences between these two thermoplastics. Here, we’ll look at the characteristics of both, and how they differ.
Acetal Copolymer: A Versatile Choice
Acetal copolymer, or polyacetal and polyoxymethylene (POM), is a semi-crystalline thermoplastic produced by copolymerizing formaldehyde with other monomers.
Key Properties of Acetal Copolymer
Chemical Resistance. Superior resistance to hydrolysis, strong alkalis, and thermal oxidative degradation, making it suitable for applications involving exposure to harsh chemicals and high temperatures.
Reduced Porosity. Minimal centerline porosity and higher density, which ensures consistent mechanical properties and low risk of voids.
Dimensional Stability. Excellent dimensional stability, which is critical for precision components requiring tight tolerances.
Glass Reinforcement. Can be chemically bonded to glass fibers for added strength.
Durability. Low coefficient of friction for high wear and abrasion resistance.
Common Applications
Acetal copolymer is often used for applications where strength, stiffness, and low surface friction are essential, as well as in environments with temperature or humidity fluctuations.
Medical Devices. Acetal copolymer is the ideal plastic in components requiring high chemical resistance and dimensional stability.
Food Processing Equipment. With acetal copolymer’s resistance to hydrolysis and chemicals, it is ideal for parts exposed to cleaning agents and varying temperatures.
Automotive Fuel Systems. Acetal copolymer’s robust chemical resistance is why it is used for fuel system components.
Delrin: Superior Strength and Rigidity
Delrin is the widely-used brand name for acetal homopolymer. This material is synthesized through the polymerization of formaldehyde, resulting in a uniform molecular structure. Because it is similar to acetal copolymer, Delrin material properties are similar; however, a major difference is that Delrin’s uniform crystalline structure improves its ability to bear cyclic loads without deforming.
Key Properties of Delrin
High Mechanical Strength. Approximately 10% to 15% higher mechanical strength than acetal copolymers, making it suitable for load-bearing applications.
Stiffness and Creep Resistance. Enhanced stiffness and creep resistance to ensure components maintain their shape under prolonged stresses, including high temperatures and humidity.
Flex Fatigue Resistance. Superior resistance to repetitive stress and flexing, extending the lifespan of parts subjected to cyclic loading.
It is important to note that Delrin has lower chemical resistance than acetal copolymer. It is also prone to a phenomenon called centerline porosity, in which the middle of a piece may become more porous after cooling, making it more susceptible to bacterial or mold growth in some applications.
Common Applications
Gears and Bearings. Delrin’s strength and wear resistance is ideal for high-precision gears and bearings.
Fasteners and Snap-Fit Components. Applications requiring high stiffness and the ability to withstand repeated assembly and disassembly use Delrin.
Automotive Safety Systems. Critical safety components in vehicles that require mechanical reliability use Derlin.
Comparing Acetal Copolymer and Delrin: Key Differences
When evaluating acetal copolymer and Delrin for an application, several critical differences emerge:
Mechanical Properties. Delrin offers higher tensile strength, stiffness, and impact resistance compared to acetal copolymers, making it ideal for structural applications requiring robust mechanical performance.
Chemical Resistance. Acetal copolymers exhibit better resistance to hydrolysis and strong alkaline environments, making them better for applications with water and chemical exposure.
Centerline Porosity. Delrin is more prone to centerline porosity, where voids form during cooling, potentially compromising mechanical integrity. Acetal copolymers offer more uniform material consistency and higher density.
Thermal Stability. Delrin maintains its mechanical properties over a broader temperature range, providing better performance in extreme temperatures than acetal copolymers.
Make an Informed Decision With W.S. Hampshire
The choice of acetal copolymer vs. Delrin is a common one for many applications. While the two thermoplastics share many properties and characteristics, they have some differences that make them more or less suitable for certain applications. It’s important to be aware of how both materials and components made from them behave in the real world.

Posted by WS Hampshire, Inc. on | Comments Off on Advantages of Using Engineering Thermoplastics in Industrial Applications
When it comes to demanding industrial applications, material performance is key. Parts need to endure punishing environments, like exposure to extreme temperatures and harsh chemicals, while maintaining their integrity. That’s why many manufacturers turn to engineering thermoplastics to ensure product longevity or reliable equipment functionality. These versatile materials can outperform metals and traditional plastics in durability and efficiency.
What Is Thermoplastic Material?
Thermoplastic materials are polymer resins that become soft and moldable when heated and then harden as they cool. This process is reversible and repeatable, however, which means that manufacturers can reshape and remold thermoplastic materials several times without altering their chemical structure.
Unlike thermoset plastics, which undergo a chemical change and harden permanently after curing, thermoplastics become homogenized liquids that retain their ability to be reprocessed. This physical rather than chemical change makes them ideal for both custom fabrication and sustainable reuse. Numerous types of thermoplastics are available to manufacturers, each with its own:
Crystalline structure
Material composition
Density
Beneficial material properties
Benefits of Using Engineering Thermoplastics in Industrial Applications
Engineering thermoplastics offer the industrial sector myriad benefits for manufacturing products.
Longevity and Sustainability
Unlike single-use consumer plastics, engineering thermoplastics are designed for durability. These materials are energy efficient to manufacture and lend your products extended lifespans, even in high-friction or chemically harsh environments. Many thermoplastics can also be recycled, lessening the burden on important resources and making them a more sustainable alternative to some metals or thermosets.
Electrical/Thermal Insulation and Flame Ratings
For electrical applications or those that expose parts to extreme temperatures, thermoplastics excel as fire-resistant electrical and thermal insulators. They offer high dielectric strength and can be manufactured to meet UL 94 V-0 flame ratings. Their ability to manage heat and prevent electrical conductivity makes them ideal for switchgear, enclosures, and other electronic housings.
Temperature Resistance
That said, manufacturers can formulate thermoplastic materials to either insulate against or conduct heat, depending on your application and heat transfer needs. Thermoplastics are known for their excellent thermal resistance. High-performance materials like PEEK and PTFE can withstand both cryogenic and high-heat conditions without deforming.
Chemical Resistance
Advanced thermoplastics offer excellent resistance to acids, alkalis, and solvents, making them ideal for industries like food processing, medical manufacturing, and chemical handling. This chemical stability helps maintain products’ structural integrity in environments where metals might corrode or degrade.
UV Resistance for Outdoor Use
Outdoor applications present a unique challenge, with materials exposed to prolonged sunlight. To address this, you can select thermoplastics enhanced with UV-resistant additives to protect against degradation. Materials such as HDPE, PTFE, and PEEK are excellent choices for components that must withstand UV radiation and external use.
Reduced Wear on Mating Parts
Thermoplastics help minimize wear on critical components that come into direct contact. Their low coefficient of friction helps protect mated parts made of aluminum and other soft metals. In many designs, thermoplastics serve as a sacrificial layer, preserving the life of more labor-intensive or costly components.
Self-Lubricating Properties
Certain thermoplastics can be engineered with self-lubricating additives that lower the need for ongoing maintenance. These materials minimize downtime by reducing the risk of mechanical failure due to friction or improper lubrication. Self-lubricating thermoplastics are advantageous for operations focused on reliability and total cost of ownership.
Weight Reduction and Enhanced Affordability
Typically, thermoplastics weigh roughly one-seventh the weight of steel. This reduction directly impacts product weight and the ease of installation and handling. Lighter components reduce the strain on lifting equipment, if any is needed at all. They also cut material and shipping costs and minimize vibrations and noise in dynamic systems. These advantages contribute to workplace safety and operational efficiency, as well.
Cost Savings Over Time
If you want long-term cost savings, thermoplastics are a good option. They’re easier to process, require less maintenance, and offer a longer lifespan than alternative materials. They also support lean manufacturing strategies by streamlining production and reducing system downtime and material waste, leading to measurable cost savings for manufacturers.

Posted by WS Hampshire, Inc. on | Comments Off on Why Material Selection Can Reduce Downtime
Many types of heavy machinery, equipment, and work vehicles incorporate bearings, bushings, and wear pads in moving parts and assemblies. They keep components aligned and spaced properly, ensure good fit between parts, and reduce wear and tear in spots where parts come together. For example,
Bearings allow for linear and rotational movement
Bushings provide a reliable bearing surface for rotary applications
Wear pads protect surfaces from excessive wear and tear
These components can be made from many different materials with different properties. When choosing the appropriate raw material, it is important to select the one with the best combination of properties that is appropriate for the application at hand.
WS Hampshire brings decades of industry experience and material expertise to develop non-metallic alternatives to traditional bearing, bushing, and wear pad materials used in industrial machinery applications. We have access to both domestic and global sources for raw materials, and full-service CNC machining and fabrication capabilities for nearly unlimited production options.
Read on to learn how bushings, bearings, and wear pads from WS Hampshire can reduce downtime, improve equipment reliability, and extend the lifespan of industrial components.
The Impact of Material Selection on Downtime
Choosing the right material for the job usually means finding the best balance between material strength, hardness, corrosion resistance, and other qualities. This allows for maximum service life of the bearing, bushing, or wear pad, and also keeps equipment and machinery in good repair. And of course, less downtime due to maintenance, repair, or replacement of worn parts.
Engineered composite materials like thermoset plastics, thermoplastics, fiberglass, and laminates have two important jobs. First they must protect equipment and parts, and second, they must be able to withstand the rigors of regular operation, such as:
Chemical Exposure
Load Capacity
Operational Temperature Range
Whether equipment failure is the result of direct damage to parts and mechanisms, or due to a breakdown of protective components like bearings or wear pads, the result is often unplanned downtime, disrupted production, and extra costs.
Extending Part Life Through Material Selection
Selecting an appropriate material for the equipment and application helps to optimize productive time in manufacturing, processing, and other industrial operations. Common non-metal materials for bearings, bushings, and wear pads generally fall into two broad types.
Thermoset plastics
These polymers undergo chemical changes due to heat, UV light, or other catalysts and become “set” in their new shape permanently. They cannot be melted or remolded, and instead will degrade when exposed to high temperatures.
Thermosets tend to be very rigid, hard, temperature-resistant, and structurally stable. They can also be reinforced with fiberglass, carbon fiber, or Kevlar for added strength and durability.
One common example is Ryertex composite materials, which are low friction, high temperature resistant, fiber-reinforced polymers. They can replace metal components in high load, high speed, high temperature applications.
Thermoplastics
In contrast, thermoplastics can be molded, formed, or machined, then can be remelted and formed into a new shape. They are impact, chemical, and corrosion resistant and are good at reducing vibrations in equipment.
Thermoplastics generally have a low coefficient of friction, high mechanical strength, stiffness, and hardness, can be mixed with fillers or rubber to improve flexibility, and take paint or coatings well.
Using the best material for your application helps to extend the service life of machines and equipment by protecting parts that touch or move against each other. Damage and wear from vibration, abrasion, or rust can be greatly reduced with bearings, bushings, and wear pads that are strong, inert barriers between pieces.
As a result, equipment components do not need to be repaired or replaced as frequently, which boosts uptime. Investing in high-quality materials increases initial costs, but there is a return on investment thanks to:
Decreased downtime
Lower labor costs
Reduced maintenance requirements
Less frequent part replacement
