FS500

Hydraulic Spring Applied Brake

Salient Characteristics

  • Single Acting Single Belleville Disc Spring Stack | 3059 lb. Tangential Force at zero friction pad wear | 6798 lb. of Clamping Force | 41,112 in. lbs. F. braking torque using 30 inch disc diameter at maximum tangential force | 14.14 sq. in. total friction pad area | Sized for brake discs ranging from 14 inch diameter to unlimited.

Engineering note: Spring applied brakes are intended for use as an emergency stop or static holding device. It is not suggested to use in continuous slip applications as torque capacity is directly related to friction pad wear. Consult Factory.
