Design Features

  • Normal closed design, safe and reliable; disc spring is applied to closed and hydraulic released.1. (Note: SBD80-160 is pressure spring, SBB250-425 is disc spring made.)
  • Maneuverable action and short braking time.2. braking time is 0.4-0.6s.
  • With limit switch the brake can realize interlocking protection and failure indication by PLC.
  • High performance (non-asbestos) lining; Steady friction coefficient; No damnification to braking disc; No sensitivity to water and high salt content air.
  • Excellent sealing ensure the brake long service life.
  • Convenient of mounting and ease of maintenance.
