Linear Unit CTJ 145

The CTJ series includes linear units with a toothed belt drive and two parallel, integrated, zero-backlash rail guides. In the linear units CTJ is used 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.

The in the profile slot driving timing belt, protects all the parts in the profile from dust and other contaminations. Re-lubrication can be done through maintenance holes on the side of the profile.
