How to Determine Bearing Shaft and Housing Fit - Baart Group

An interference fit is precisely the opposite of the clearance fit. In this fit, often referred to as a press-fit, there is interference between the bearing ring and its mating part. The bearing bore is smaller than your shaft diameter, or your bearing O.D. is larger than your housing bore.

Interference fit: A type of fit in which the minimum diameter of the shaft should always greater than the maximum size of the hole. Bearing Internal Clearance: (Radial and axial internal clearance) The distance one bearing ring can be moved relative to the other.

10. Fits | Engineering Information | MinebeaMitsumi Product …

10. Fits. When a ball bearing is used, it is always fitted to a shaft and/or a housing bore. Fit is a value of tightness between the shaft and bearing bore, as well as the fit between the housing and bearing outer diameter, when the bearing is installed. Fits are classified into clearance fit, intermediate fit, and interference fit.

Shaft & Housing Fits - kmlbearingusa

Shaft Fits. To get the best performance from a rolling contact bearing, the fit between the inner ring and shaft and outer ring and housing must be correct. If the mating surfaces lack interference, the inner ring may spin on the shaft or the outer ring may move in the housing. This unwanted movement is called ‘creep’.
