Nexen Ball Screw Brake BSB

Nexen BSB is a spring-engaged, air-released brake designed for zero backlash holding of the free end of a ball screw spindle. It provides high stiffness or holding in power-off situations without a loss of accuracy. These modules mount between the servo motor and the gear reducer or on the free end of a ball screw spindle.

The low backlash and coupling combination provides a high degree of accuracy for holding ball screw positions. 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
  • High torsional rigidity
  • Bi-directional braking
  • Fast engagement
  • Meets IP67 dust and waterproof standards
  • Operates in vertical and horizontal applications
  • Allows thermal expansion of ball screw
