Ressource KRW Product Component

By default, cylindrical roller thrust bearings consist of shaft washer, housing washer and roller cage assembly and can be ordered as standard bearings.

Single-sided and double-sided cylindrical roller thrust bearings can be combined of cylindrical roller thrust cage assemblies as well as housing washers (GS) and shaft washers (WS) or, alternatively, race washers (LS). All components can be ordered independently.

 

Shaft Washers

Shaft washers are standardised in DIN 616 and ISO 104. The bore features a precise centre fit and is used to align the bearing to the shaft. This is why the bore of the shaft washer is smaller than the bore of the corresponding housing washer. The outer diameter of the shaft washer is smaller than the outer diameter of the corresponding housing washer.

Shaft washers are abbreviated with WS and put in front of the bearing number as letter code.

 

Housing Washers

Housing washers are standardised in DIN 616 and ISO 104. The outer diameter is designed with a precise centre fit and is used to align the bearing to the housing. This is why the outer diameter of the housing washer is larger than the outer diameter of the corresponding shaft washer. The bore of the housing washer is bigger than the bore of the corresponding shaft washer.

Housing washers are abbreviated with GS and put in front of the bearing number as letter code.

 

Race Washers

Race washers are not superfinished in their bore nor in their outer diameter, so they are not suitable for centring the bearing. They can be used in applications where there is no exact centring required.

Race washers are abbreviated with LS and put in front of the bearing number as letter code.
