Bearing internal clearance (fig 1) is defined as the total distance through which an internal clearance other than Normal are identified by the suffixes C1 to C5.
C3, C4 and C5 bearings are bearings that have an additional internal radial clearance to cope with high speed environments where excess heat is generated.
