Timco’s cast nylon sheaves are increasingly found on a wide variety of lifting equipment. They often replace sheaves made of cast iron or steel. Today, Timco’s sheaves can be found on nearly any type of crane including gantry, tower, rough terrain, and crawler, truck, and pedestal cranes. They are also used in equipment for the wire drawing and cable stranding industries, on forklifts, telehandlers, manlifts, and mobile drill rigs and in many other mechanical systems. Timco is the largest supplier of machined non-metallic sheaves in North America. We are proud to offer our customers sheaves of all sizes and designs.
Sheaves are grooved wheels or pulleys used with rope or chain to change the direction and point of application of pulling force. Timco’s fabricated sheaves have considerable advantages over cast iron or steel sheaves. Benefits of using our sheaves are found on the following pages. This brochure also details design guidelines for cast nylon sheaves to improve your equipment’s safety and efficiency. Selecting sheaves requires knowledge of product specifi cations: type of belt or rope to be used, bearing size and type, and any dimensional restrictions. A worksheet to gather information to design a sheave is found on page 9. An experienced Timco sales engineer would be happy to assist you in your sheave design.
