Internal clearance

SKF four-row cylindrical roller bearings are normally produced with the C3 or C4 radial internal clearance required for rolling mill bearings. Bearings for mounting with a loose fit on the roll necks ("G" design) generally have C2 radial internal clearance.
SKF six-row cylindrical roller bearings are produced with the radial internal clearance specified on the order.
The clearance values, where standardized, conform to ISO 5753:1991 and are given in table for bearings with cylindrical bore and in table for bearings with tapered bore. They are valid for unmounted bearings under zero measuring load.
