  • Bearing Tolerances & Clearances - American Roller

    One exception is the fit for thin inner race cylindrical roller bearings that are heavily loaded, i.e. C/P less than 3. A common practice for sizing shaft journals that mount the two or more bearings with the same bore size is to use the recommended shaft O.D. for the most heavily loaded bearing in all locations.

  • Selecting fits | SKF

    Where the outer ring should be able to move axially in its housing, a loose fit must be used. However, a loose fit can result in housing wear. Where this cannot be tolerated, either protect the bearing seat surface or select a bearing that accommodates the axial displacement within itself (cylindrical roller, needle roller or CARB bearing).

  • Tolerances | SKF

    The tolerance class of a bearing cannot always be determined from its designation suffixes. Where the tolerance class is standard for the bearing, it is not specified in the designation suffixes. For information about SKF bearings that have a tolerance class better than class 5, refer to Super-precision bearings .
