12 Needle roller thrust bearings
Bearing washers 811 series shaft (preix WS) and Fig. 8
housing washers (preix GS)
LS series universal washer
Bearing washers are required in applications
where adjacent machine components cannot • are used primarily with cylindrical roller
serve as raceways and cage thrust assemblies
Appropriate washers are listed in the • can also be combined with needle roller
product tables, page 906 and must be and cage thrust assemblies
ordered separately, because of the number • can be used in high-speed applications
of possible combinations where accurate centring of the bearing
The following series can be combined with washers is required

• are available for 4 ≤ d ≤ 160 mm
• can be used to provide a cost-effective
bearing solution, if adjacent machine
components are not hardened, but have
adequate stiffness and the requirements
to geometrical tolerances are moderate
