Thrust Washers

Washer ConstructionThe thrust washer is constructed by bonding woven Teflon® fiber fabric liner to one or both faces of a washer substrate. The substrate may be metallic, such as low carbon steel, stainless steel or aluminum. It may also be a non-metallic substrate such as NEMA grade G-10 or NEMA grade C. Standard washers are made with G-10 substrate.

Size rangeStandard and special inch and metric sizes are available from 3/8” to 18” outer diameter.

Load CapacityTypical dynamic loads: 4,000 to 20,000 psi Ultimate strength: 60,000 psi for G-10 washer substrate.

Electrical PropertiesThe G-10 substrate material is an electrical insulator. Its dielectric strength is about 550 volts per mil. Since the back-up material is electrically non-conducting, electrolytic or galvanic action will not take place between it and the housing or the shaft.

Chemical PropertiesFilament bearings are typically resistant to most chemicals. Due to the wide range of exposures, specific conditions must be checked. Consult a Rexnord engineer for specific chemicals.
