Miki Pulley’s BXW spring-actuated electromagnetic brakes provide reliable dynamic braking when the power is disengaged and excellent performance in long-term holding applications.

BXW brakes use internal compression springs to provide power-off, fail-safe braking. The primary moving part in this robust but simple brake design is the armature plate. When actuated, the brake compression springs push the armature plate into the friction disc when power is disengaged. This feature provides fail-safe braking and allows the brake to maintain position over long periods of time, thus preventing machinery from “coasting” when powered off.

The BXW brakes function at full torque rating “right out of the box” so no startup run-in is needed. They’re available in three different models for either single use braking, holding or both braking and holding. Depending on size selected, BXW brakes are suitable for small and large applications including use with servo motors.

Additional features include: quiet operation, high holding torque, space saving, long service life, stable, reliable braking power and manual release mechanisms.

Depending on the model, BXW brake specifications range from:

• Brake torque: 0.88 ft/lb to 0.369 ft/lb (0.12 Nm to 5.2 Nm)
• Brake outer diameter: 1.457 in. to 2.953 in. (37 mm to 75 mm)
• Ambient temperature: 14 °F to 104 °F (-10 ℃ to 40 ℃)
