This indexing table is used to test metal balls for cracks and dimensional accuracy. xiros® polymer ball bearings are used in this application as wheels for the ball trolleys. Crucial to the use of polymer ball bearings here was the bearing's freedom from maintenance and lubricants. In addition, compared to the metal versions the outer rings of the ball bearings do not scratch the application track.
Advantages of xiros® polymer ball bearings at a glance:
Lubricant free
