Shaft and housing hole tolerance zone

Shaft tolerance zone

For most occasions, when the shaft rotates and the radial load direction does not change, that is, when the bearing inner ring rotates relative to the load direction, a transition or interference fit should generally be selected. When the stationary shaft and the radial load direction are not changed, that is, when the bearing inner ring is stationary relative to the load direction, a transition or a small clearance fit can be selected (too large clearance is not allowed).

Housing hole tolerance zone

When selecting, pay attention to avoid the clearance fit for the outer ring that swings or rotates in the load direction. The equivalent radial load also affects the fit of the outer ring.
