Roller bearing cage for rotary joint, roller bearing or slewing bearing for machinery and plant engineering, has multiple additional receiving units, particularly material recesses in form of bores, for receiving inserts

摘要

The roller bearing cage (10) has multiple additional receiving units, particularly material recesses in the form of bores (80), particularly in the form of blind bores or alternatively in the form of through holes, for receiving inserts (50). Each insert is contacted with the roller bearing cage along its bore diameter or by its diameter. Each insert is detachably or non-detachably inserted in the roller bearing cage. Each insert is made of brass or plastic. The roller bearing cage is made of steel. The inserts are alternatively made of iron- or non-iron material.
