Note
The ball transfer units comprise a housing with integrated bearing shell, a cover, a load ball and several supporting balls. For use in measuring instruments, material conveyance in clean rooms and miniature mechanisms.

These ball transfer units are not designed for high impact loads.
Impact type loads can cause damage to the ball, track or housing leading high impairment of the function and service life of the ball transfer unit.

For applications with impact loads we recommend using our heavy-duty rollers or those with solid steel housings, which are designed for high mechanical demands.


General tolerances ± 0.3mm.
