Friction Brakes

Air or spring-engaged, shaft-mounted friction brakes come with tapered bores to accept QD bushings or straight, bored and keyed-to-size disc hubs. Bushings are available to reduce the size of the standard, straight-bore models. Air-engaged brakes are used for stopping, holding, controlled deceleration, and tension control. Spring-engaged brakes are excellent stopping and holding devices. Multiple sizes provide torque up to 10,000 inlbs.

Nexen's drum brakes are actuated with a diaphragm-sealed actuator that forces a brake shoe on a drum surface to provide the braking torque. Brake drums are bored and keyed to fit standard shafts. The brake shoes are clamped on the outside of the drum to provide brake torque up to 3750 inlbs. Hinge top models offer a convenient feature to change rolls when the brake is used in tension control applications.

Caliper brakes are used in controlled deceleration, cyclic stopping, holding, emergency stops, and tension control applications. Nexen offers a wide variety of caliper brake designs, including air actuated/spring-released, spring engaged/air-released, and spring engaged/hydraulic-released models. Several disc diameters up to 24-inches are offered to provide torque up to 50,000 inlbs. Multiple calipers can be used on a single disc to increase torque and accommodate various disc thicknesses.
