Pneumatic Torque Limiters provide overload protection.
Mechanical Power Transmission

Pneumatic Torque Limiters provide overload protection.

Using ball/detent interface and proximity sensor, single-position TL Series immediately disengages machine shaft when excessive torque or machine jam occurs, protecting downstream equipment and product from damage. By utilizing pneumatic actuation, units facilitate remote trip-out torque adjustment via air regulator, allowing overload protection while machine is in use. Limiters are available in...

Ball Screw Brake offers zero backlash for precision holding.
Mechanical Power Transmission

Ball Screw Brake offers zero backlash for precision holding.

Functioning as redundant braking or load holding mechanism, ball screw/stage brake is high-torque, spring-engaged, air-released brake acting on non-driven end of ball screw. It serves as safety brake in event of mechanical defect in driveline, particularly in Z-axis applications. Featuring bi-directional braking, it operates in both vertical and horizontal applications. Brake allows thermal...
