Precision Shafts and Bushes
Ball bearing bushes are rolling bearings for longitudinal movements (linear bearings) that run on hardened and grinded shafts. Whilst the longitudinal movement is taking place, the ball bearings are moved back into the load zone in constant circuits via sealed orbits.
The advantage of these products can be seen by the fact that they have low friction and low breakaway force properties. Depending upon the application, the sliding bushes can be an alternative to the ball bearing bushes.
The shafts are hardened in an inductive manner and have been grinded. This prevents shrinkage.
Areas of application:
Shaft bushes and ball bearing bushes can be used in almost all sectors. For example, these products are used in column frames in pressing / punching / deburring machines, but are also used as simple guides in special machines and handling units.
