  • Operation:

    spring activated, with pneumatic release, mechanical

  • Other characteristics:

    safety, high-torque, low-inertia, zero-backlash, bi-directional, ball screw


The Nexen 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 safety 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 ball screw position. An expanding shaft/clamping hub coupling connects the brake shaft to the end of the ball screw. This coupling comes with an elastomer insert with high torsional stiffness.

• Low backlash for precision holding
• Spring engaged, air released
• Low inertia
• Bi-directional braking
• Fast engagement
• IP67
• Operates in vertical and horizontal applications
