Salient Characteristics

  • Single Belleville Disc Spring Stack | 465 lb. Tangential Force at zero friction pad wear | 3315 in. lbs. F. braking torque using 16 inch disc diameter at maximum tangential force | 4.0 sq. in. total friction pad area | 1033 lbs. clamping force | Unlimited 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.
