Radial internal clearance SKF single row cylindrical roller bearings are manufactured with Normal radial internal clearance as standard. Most of the industrial bearings are also available with C3 radial internal clearance. Some of the bearings can even be supplied with the smaller C2 or the appreciably greater C4 clearance. In addition some bearings are produced with special reduced clearances. This special clearance corresponds to a section of a standard clearance range or to sections of two adjacent clearance ranges. Bearings with non-standard clearance or with the special reduced clearances can be supplied to special order. The actual clearance limits for bearings with a cylindrical bore are provided in table F| and are in accordance with ISO 5753:1991. They are valid for unmounted bearings under zero measuring load. The separable components of all SKF bearings with standard clearance as well as those with reduced clearance are interchangeable. |
