HOW MUCH CLEARANCE DO YOUR BEARINGS NEED?

shaft + .0006" for the bearings = .0026" total clearance variation possible due to mating part manufacturing tolerances. If our minimum assembled clearance is just .0005", this makes the maximum possible .0031" (.0005" min. + .0026 tolerance range = .0031" max.). For normal passenger car application, .0031" of bearing clearance

Internal clearance | SKF

Bearing internal clearance is defined as the total distance through which one bearing ring can be moved relative to the other in the radial direction (radial internal clearance) or in the axial direction (axial internal clearance).In almost all applications, the initial clearance in a bearing is greater than its operating clearance. The difference is mainly caused by two …
