Modulated Hydraulic Pressure Source Controls Brake Torque
The 520 Series hydraulic apply calliper disc brake for on- and off-highway service braking applications uses a modulated hydraulic pressure source, such as a master cylinder, to control brake torque. The brake can be mounted in a vertical or horizontal position, and linings can be replaced without removing the brake.
The brake includes two ductile iron calliper halves that are pressurized by a single inlet port cross-over tube feature, which allows hydraulic pressure to actuate the 2.25-inch diameter piston in each half. The unit provides for continuous duty pressure of 1,000 psi and intermittent duty pressure of 1,500 psi. Approximately 17 pounds, the brake needs a minimum disc diameter of 15 inches.
The calliper disc brake features a spring-operated lining retractor mechanism that maintains a constant lining-to-rotor disc clearance distance whenever the brake is not applied to reduce unnecessary lining wear. The lining contact area totals 12.4 square inches, with a usable lining thickness of 0.32 inches on each side. Linings can be replaced without disassembling or removing the brake for reduced maintenance time and costs.
Mounting in either a horizontal or vertical position, the brake is flexible and installs simply. The unit can be attached directly to a threaded hanger or clamp.
