Works as An Emergency and Holding Brake In Compact Automated Systems

Plymouth, Minnesota: Miki Pulley’s unique BXR power-off engaged brake may serve as an emergency brake and holding brake, a crucial feature for protecting compact designed automated systems. 

BXR spring-applied brakes provide versatility in space and weight savings. Their unique, low-profile design is 2/3 the thickness of other brakes in the Miki Pulley brake lineup.
In successful articulating joint applications where the cantilevered load must be minimized, the extra thin BXR brake operates in this way:
Voltage flows to the coil to open the brake and allow free rotation. When power disengages from the coil, internal compression springs push the armature plate toward the rotor disc, halting it against the top plate. The square/splined rotor hub affixed to the input shaft interfaces with the rotor disc, holding rotational movement.
The Miki Pulley BXR brake is highly versatile and an ideal space and weight-saving option for servo motor applications.
The operating specifications for BXR Spring Applied Brakes are as follows:
  • Brake torque: 3.688 ft-lb ~ 40.566 ft-lb: (5N · m ~ 55N · m)
  • Brake outer diameter: 3.287” ~ 7.280”; (83.5mm ~ 185mm)
  • Ambient Temperature: 14 F ~ 104 F; (-10 ℃ ~ 40 ℃)
Miki Pulley also manufactures even smaller brake models with the designation BXR-LE for miniature applications 0.06 Nm to 3.20 Nm.
