Single direction bearings
- class A, light preload
- class B, moderate preload
The amount of preload depends on various factors and applies to bearing sets in back-to-back or face-to-face arrangements. Preload values are not standardized and are listed in the product table. The values do not cover influences from fits or operating conditions.
Bearing sets with a non-standard preload can be supplied on request. These bearing sets are identified by the designation suffix G followed by a number. The number is the mean preload value of the set expressed in daN.
Bearing sets consisting of three or four bearings have a heavier preload than sets with two bearings. The preload for these bearing sets is obtained by multiplying the values listed in the product table by a factor listed in table 1.
Double direction bearings
Bearings with a different preload can be supplied on request.
