FS400

Hydraulic Spring Applied Brake

Salient Characteristics

  • Dual Belleville Disc Spring Stacks | 1859 lb. Tangential Force at zero friction pad wear | 13,260 in. lbs. F. braking torque using 16 inch disc diameter at maximum tangential force | 8.19 sq. in. total friction pad area | 4130 lbs. clamping force | Up to 16 inch disc diameter

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.
