Customizable Material Solutions

Above all else, we are an engineering firm that can take your technical requirements for sheaves and translate them into cost effective solutions to meet or exceed the performance required of your application. Selection of the proper sheave material plays an important role in ensuring strength, durability, and overall performance in your application. Sheaves Inc. has been the number one source for the wire-rope industry, designing and providing custom engineered wire rope sheaves that meet your specific needs and rigors of your application. Trust our engineering expertise, and let us suggest a suitable material in your next challenging application.

Considerations when choosing a Sheave Material

pulley for wire rope lifting applications

Carbon Steel/Stainless Steel

1045 Steel: Machined from Round bar, hardened up to 35-40 Rockwell Hardness
A572 GR50 Steel: Machined from Round bar, hardened up to 35-40 Rockwell Hardness
Stainless Steel: Less Hardened than carbon steel; increased corrosion resistance

Cast Nylon

Cast nylon sheaves are superior to aluminum or steel sheaves for wire rope load applications

Service Life: exceptional durability and performance; significantly improves wire rope life in operation
Corrosion Protection: impervious to rust and salt water corrosion, no paint or coating needed
Reduced Weight: one-seventh the weight of steel sheaves of the same dimensions, one-half the weight of aluminum sheaves


Light weight option for high speed applications. Resistant to chemicals, temperature, and corrosion. Durable in wire and cable processing applications

SX Polymer

A new thermoset material that has very good wear and improved strength characteristics. Prmary material used in BOMCO Replacement Sheaves.
Color: Off White Temperature range: -60°F to 250°F

Gar - Dur

Our custom process sheaves are most often machined from Gar-Dur, the densest, toughest thermoplastic today. GAR-DUR properties, such as toughness and abrasion resistance with light weight, make it ideal for high speed sheaves processing wire and cable.
Color: Normally yellow but also available in black for UV resistance. Temperature range: -460°F to 200°F

Other UHMW

Manufacturing methods limit GAR-DUR material to 23″ OD and 2″ OAW. For sheaves beyond those dimensions we use virgin UHMW cut from stress-relieved sheets.
Color: Off White. Temperature range: -220°F to 180°F

High Density Polyethylene (HDPE)

HDPE has similar properties to UHMW but lower properties and prices. Ideal for tubing, hose, synthetic rope, and similar materials that have less demanding wear and load requirements. Color: Off White. Temperature range: -180°F to 160°F

Ceram-P(TM) Filled UHMW

Ceram-P is ceramic filled UHMW recommended for high load and severe sliding abrasion. It is a shatter resistant alternative to sintered ceramic but substantially heavier and more expensive than UHMW.
Color: Lime Green. Temperature range: -60°F to 220°F

Nylon (Polyamide)

A self lubricating, general purpose nylon that offers outstanding wear and abrasion resistance, chemical resistance and low friction. Higher cost, lower impact resistance, higher compressive strength than UHMW.
Color: Off White. Temperature range: -60°F to 190°F
