Fits for radial ball bearings

The main dimensions of radial ball bearings have tight tolerances. In order to achieve a good bearing seat while at the same time being easy to assemble, the outside diameter of the shafts or the inside diameter of the bores are tolerated according to the fit system. The recommended shaft and bore fits are given below.

Recommended fit for the shaft

Shaft diameter         Dimensional tolerance for light loads (P ≤ 0,05 C) Dimensional tolerance for normal to high loads (P > 0,05 C)
Dw ≤ 10 mmjs5
10 < Dw ≤ 17 mmjs5j5
17 < Dw ≤ 100 mmj6k5
100 < Dw ≤ 140 mmk6m5
140 < Dw ≤ 200 mmm6
200 < Dw ≤ 500 mmn6
Dw > 500 mmp7
C = basic dynamic load rating | P = equivalent dynamic bearing load
