Selecting initial internal clearance | SKF

The operating clearance required for a bearing to perform satisfactorily is appliion dependent (Importance of selecting correct clearance/preload). You must ensure that the bearing has a minimum initial internal clearance of a size that, when it is reduced by the effects of mounting and other influences, is equal to or greater than the required minimum operating clearance.
