Ball Screw Brakes

Motion Drives & Controls can supply the full range of Nexen Ball Screw Brakes that encompass a high-torque, spring-engaged brake acting on the machined end of a ball screw. They serve 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 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.

Features:

• Low backlash for precision holding
• Spring engaged, air released Low inertia
• High torsional rigidity
• Bidirectional braking
• Fast engagement
• Meets IP67 dust and waterproof standards
• Operates in vertical and horizontal applications
• Allows thermal expansion of ball screw
