Machine Tools and Processing Machines

In no other product are the requirements on the accuracy of the bearings used consistently as high as in a machine tool. Whether spindle, rotary axis or rotary table, the bearing arrangement defines the limits of the machine tool like no other machine element. KRW bearings stand for highest precision. KRW is an innovator and partner to the world's best machine tool manufacturers to improve their products further.



KRW bearing solutions can be found in large spindles, rotary tables, steady rests and many other applications. In numerous realised special solutions these are often much more than just a bearing. From pre-set bearing packages to ready to install solutions including positioning systems and connections for sensors, pneumatics, hydraulics and lubrication, KRW makes everything possible to provide its customers with the best individual solution for their application.


Spindle working on an workpiece


KRW develops and manufactures bearings for large spindles. From standardised spindle bearings to multi row cylindrical roller bearings in ultra-precision for roll grinding machines or radial bearings in rotary tables, the KRW portfolio offers highest precision for perfect machining results.

Special Bearing Solutions

The concepts for machine tools are becoming increasingly complex and must follow the machining task to be successful. This is a given for KRW and therefore, the same applies to the bearings. We don't want to limit the engineers of our customers because of a bearing that does not seem to be available. Many innovative bearing concepts have been designed and built by KRW and some machine concepts have only been made possible in this way.


Special Bearing Solutions

Services and Engineering

KRW fully supports its customers from the design of the bearing arrangement to advice on installation and lubrication. Ideally, the cooperation starts with the first draft. Based on the requirements from the subsequent machining process, KRW recommends the best bearing solution. If this does not yet exist, we will develop it from scratch. One such example is our ROTAB® DBS, which is the only standardised rotary table bearing of this type, developed for direct drives, which has redefined the feasible speeds in large machining centres.
