BSFI 300 Series Brake Caliper

The BSFI 300 fail-safe, spring-applied, hydraulically-released brake family includes the following single and dual piston models to meet specific customer performance and footprint requirements:

  • BSFI 300 DS
  • BSFI 300 MS
  • BSFI D300 DS
  • BSFI D300 MS

These fail-safe brakes can be used for a range of different purposes, such as parking and emergency stopping in case of power failure of driven equipment. The brake spring packs are sized to suit the individual specific braking torque requirements of the application. A range of indicators are available as accessories and can be fitted to the brake to detect and monitor the status of the brake functions, such as: brake pad wear, brake on/off status and brake lining temperature.

Dual-spring and quad piston versions consist of two caliper halves designed for mounting on a bracket. These brakes have two sets of spring packs making the intervals between required brake adjustments longer compared to a mono-spring type brake.

Mono-spring brake versions consist of three parts: a caliper half-fitted with a spring pack(s) and a passive caliper mounted on a base plate suitable for side mounting. The brake caliper assembly is free floating on guide shafts allowing for axial disc movement.
