Nexen BD Caliper Brakes Offer Higher Clamping Force

Nexen Group, Inc.

Brute disk caliper brakesVadnais Heights, MN – Nexen Group, Inc. offers three models of BD (brute disk) caliper brakes: air actuated, spring actuated/air released, and spring actuated/hydraulically released. The innovative BD design utilizes arms to provide a mechanical advantage, allowing higher clamping force. (Stopping power can be multiplied by installing additional caliper brakes on each disc.) Torque ranges from 8,000 to 23,000 in-lbs., with disc diameters from 12 to 24 inches. Actuators mount on either side of the brake. Connections can be rotated 360° around actuator axis, and all pivot points have life lubricated bearings. Brake shoes are mounted with detent pins for quick replacement. Larger, curved brake shoes with more contact area are available for longer life and higher peak input rate.

Highlights of the BD caliper brake (features vary by model) include:

  • Static brake torque: 8,000 to 23,000 in-lbs.
  • Maximum disc speed: 3200 RPM
  • Optional discs: 12 to 24 in.
  • Disc thickness: 0.50 to 1.00 in.
  • QD Bushing compatible for shaft sizes up to 3.875 in.
