Specification :

Thrust washers mainly divided into AS type, WS type and LS type. The AS type is made by high quality spring steel sheet through stamping. Constantly, the thickness being 0.8-1mm, applied to the fittings that can not be harden but with enough rigidity and geometric accuracy. Axle ring(WS), Seat ring(GS) and Bearing washer(LS) are made by spring steel through heat treatment, it will be used with thrust cylindrical roller bearings or cage assemblies.

Series:
Bearing No. Characteristics of Structure
AS
WS811 Nominate dimension of inner diameter is same with diameter of axis, thin washerB=1 thick washer B2.75

GS811 Nominate dimension of inner diameter=diameter of axis +1~2mm, thick washer.

LS Nominal dimension of inner diameter is same with diameter of axis; thick washer demands low precision and they can be treated as shaft washer or seat ring.

ZS Axial Orientation of thick washer: inner axis is less than diameter of axis. Orientation of double directional pressure bearing seat: inner diameter is less than diameter of axis.
