Internal Radial Clearance of ball and roller bearings is an important parameter in obtaining proper machine operation, optimal bearing life, and a reasonable operating temperature. With radial bearings of the deep groove ball, cylindrical roller, and spherical roller types, the term Internal Radial Clearance - IRC - is commonly employed.

SKF Explorer bearings are interchange-able with previously specified SKF standard bearings of the same type and size. These bearings are included in the relevant product tables and are easily identified by an asterisk (*) in front of the bearing designation.

sure bearing is square on the shaft and then apply pressure using a hammer or arbor press. To mount larger bearings that are not easily pressed onto a shaft, heat the bearing to a maximum temperature of (250°F). The bearing may be heated in clean oil or in a 10% - 15% emulsion of soluble oil for 30 minutes to 1 hour depending on bearing size.
