  • Static Torque capacity up to 1040In. Lbs. @ 80 psi w/16" Disk
  • Brake Torque may be doubled ortripled by adding brake calipers
  • Air Actuated
  • Arc contoured shoe provideslarge friction area, for greaterfacing life and stability
  • Easily mounted in any positionwith T Bracket
  • Disc Speeds up to 4500 rpm
  • Disc Hubs use QDBushing“SK” for shaft sizes from 0.5 to2.125 inches/Standard Keyway.
  • Spring return eliminates discdrag when disengaged
  • Optional Air Hose Assemblycomes with required fittings andhose for both air inletsThe Disc, Hub and Air Hose mustbe ordered separately. QDBushingis customer furnished. Optional discs available from 10” to 16”diameter.

Nexen BD Caliper Brakes

A robust caliper brake with either air actuation or spring actuation (with air & sping emergency braking provision) this caliper is ideal for industrial applications requiring holding, stopping of high inertial loads, controlled deceleration or tension control.

Combined with a cast iron vented disc it allows very high heat disapation and thermal loads.

Customers can now take advantage of a high performing brake at an affordable cost for their emergency stopping and/or holding applications.

Nexen's BD Caliper Brake is spring applied and its compact actuator is hydraulically released, with mounting capabilities on either side of the brake. Capable of high cyclic duty, this BD Caliper Brake is ideal for rapid start/stop applications. Its simple design with very few seals and moving parts make installation and maintenance easy.

The brake shoes mount with detent pins for quick friction facing replacement and all pivot pins have life-lubricated pivot-point bearings. The BD brake has proven itself by its low-cost and high performance in several types of applications and industries such as sawmill, steel mill, bulk material conveyor, automotive production, wind turbine, amusement parks, ski lifts, pulp and paper, wire rolling/drawing and textile.
