Nexen Ball Screw Brake BSB
Industrial Clutch Parts Ltd. supplies a complete range of Nexen Group ball screw brakes. Available in various bore sizes and flanges to fit almost any brand of motor.
Nexen ball screw brake (BSB) 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.
- Min. Holding Torque: 2 - 125 Nm
- Bore Sizes: 5 - 35 mm
- Max. Speed: 10,000 rpm
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
