Do you want to know the bearing seat tolerance and corresponding cooperation information?

The tables in this section provide information on bearing tolerances, bearing seat tolerance, and corresponding fits

With this information, you should be able to easily identify the maximum and minimum values ​​of fits when using ISO bearing seat tolerance and bearings (and bores and outer diameters with normal tolerances). The SKF bearing calculator provides similar functionality for each individual bearing.

When d ≤ 30 mm or D ≤ 150 mm, the table is not applicable to tapered roller bearings; when D ≤ 150 mm, the table is not applicable to thrust bearings. The diameter tolerances of these bearings deviate from the normal tolerances of other rolling bearings.

Upper and lower limits of tolerances for inner and outer diameters of ordinary tolerance bearings
Upper and lower tolerances for shaft or bearing seat tolerance bore diameter deviations in accordance with the relevant tolerance classes in accordance with ISO 286­2
Minimum and maximum theoretical interference (-) or clearance (+)
Minimum and maximum possible interference (-) or clearance (+) ± 3σ

The values ​​are listed for bearing seat tolerance for the following tolerance classes:

f5, f6, g5, g6, h5 
h6, h8, h9, j5, j6 

js4, js5, js6, js7, k4
