Linear Unit MRJ 65

The MRJ linear units have toothed belt drive and compact dimensions to provide high performance features such as high speed and good accuracy. For very high speeds, up to 10 m/s, the track rollers (journal bearings) of the type MRJ are particularly suitable.

The unit MRJ have a pre-tensioned steel reinforced AT polyurethane timing toothed belt. In conjunction with a zero-backlash drive pulley high moments with alternating loads with good positioning accuracy, low wear and low noise can be realized.

All parts in the profile are protected from dust and other contaminations. As corrosion-resistant protection strip is available as option.
