About our Ball Screw Brakes

Nexen’s Ball Screw Brake is a high-torque, spring-engaged brake acting on the machined end of a ball screw. It serves as a primary or redundant brake to prevent back driving if a power loss or mechanical defect occurs in the driveline.

The low backlash and coupling combination provides a high degree of accuracy for holding the ball screw position. An expanding shaft/clamping hub coupling connects the brake shaft to the end of the ball screw. The required coupling comes with an elastomer insert with high torsional stiffness.

Selection
Nexen offers an off-the-shelf braking solution for any ball screw application. These spring-engaged, air-released brakes eliminate the performance problems associated with electrical brakes for consistent, long-lasting performance.

Ball Screw Brakes provide reliable holding in a compact package
During a power loss, the motor has no holding torque allowing the ball screw to back drive and the load to drop. Ball screw brakes connect to the machined end of the ball screw to prevent back driving, load drops, and equipment damage during a power loss. Holding force up to 125 Nm (1100 in-lbs.)
