Safety Brake for Robotic Arms



Featuring a low profile design, this fast response brake may be used for robotic arm applications.

Miki Pulley has introduced its BXR Spring Applied Brakes for direct sale to OEMs in North America.

The BXR safety brake may serve as an emergency brake, as well as a holding brake. "Its unique, low profile design is 2/3 the thickness of other brakes in our lineup," said a company spokesperson. "In addition to saving space, weight is also reduced.

"The BXR is an ideal safety brake for robotic arms. In these applications, when a catastrophic power failure occurs, robotic arm movement must be halted immediately to prevent mechanical system collapse and equipment damage. In the event of power failure using the BXR safety brake, compression springs engage and capture the brake's rotor hub immediately stopping arm movement."

Designed with a thin profile, the BXR saves space in articulating joints. Idling wear is also reduced because of its lightweight construction.

The BXR brake may also be installed on the output face of a servo motor, serving as a power-off holding brake. This can be an advantage when the overall assembly size must be contained in a small envelope.

Additional design benefits include a single friction plate, which provides fast response in high cycle applications. Armature engagement is smooth and operates with no chatter. The BXR may function dually as an emergency brake and a holding brake.

BXR operating specifications are:

  • Brake torque: 3.688 ft. lb. - 40.566 ft. lb. (5 Nm - 55 Nm)
  • Brake outer diameter: 3.287" - 7.280" (83.5 mm - 185 mm)
  • Ambient temperature: 14 °F - 104 °F (-10 °C - 40 °C).
