Linear Unit MTJ ECO 40

The MTJ ECO series linear unit is a powerful and cost-effective linear unit with toothed belt drive and a zero-backlash ball rail guide system for easy and accurate linear movements.

The linear unit MTJ ECO uses 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.
