Inch dimensions Bearings
 
Inch single row cylindrical roller bearings for the aftermarket also belong to the SKF standard assortment. The dimensions of these bearings follow the British Standard BS 292:Part 2:1982. This standard has subsequently been withdrawn in 1997 as a consequence of metrication. It is recommended not to use these inch bearings for new bearing arrangement designs.

Designs
Inch bearings, series designations CRL and CRM, have an inner ring with two integral flanges while the outer ring has no flanges (fig). Accordingly their design conforms to that of the metric N design bearings, which can accommodate axial displacements of the shaft relative to the housing, within the bearing.

Cages
Depending on the size, SKF inch single row cylindrical roller bearings are equipped as standard with one of the following cages:

– Unhardened pressed window-type steel cage, roller centred, no designation suffix.
– Two-piece machined brass cage, inner ring centred, designation suffix MB.

Tolerances and internal clearance
Inch bearings are manufactured to Normal tolerances, according to standard BS 292:Part 2:1982 and with Normal radial internal clearance, which conform to ISO 5753:1991.
