Design considerations

For general information, refer to Design considerations.

Abutment dimensions

The diameter of the thrust bearing support surface in the housing should be at least 0,5 mm larger than the dimension D1 or D2 (fig. 1, → product table for needle roller / thrust ball bearings and needle roller / cylindrical roller thrust bearings).

Shaft and housing tolerances

Table 1 provides tolerance classes for the housing bore and shaft to obtain suitable fits and an appropriate operating clearance for combined needle roller bearings with or without an inner ring.

For additional information about raceways, refer to Raceways on shafts and in housings.
