Linear Unit MTJ 80
The MTJ linear units have toothed belt drive and compact dimensions to provide high performance features such as high speed and good accuracy.
The unit MTJ 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.
Contact Rollco for CAD-files.
