Torque range – 30,000 to 90,000 lb-in (Clutch), 10,000 to 20,000 lb-in (Brake)
Typical applications – Turret Punch Presses

CCB – CLUTCH/BRAKE COMBINATION

Wichita Clutch/Brake Combination (CCB) units provide fast, smooth cycling for stamping presses and metal forming equipment by combining a high performance clutch and spring set brake in a compact assembly. A single air tube actuates both the single plate clutch and the single plate brake.

Braking force: 809 to 50,600 lb (3.6 to 225 kN)

Typical applications: Cranes, conveyors, mining, steel mill machinery, nuclear power, oil field machinery

DBA BRAKES

Model DBA brakes are spring applied, pressure released, disc style brakes. They develop equal torque in either direction of rotation. Their torque and thermal capacities allow them to be used in the most demanding applications.

Brake construction and operation is shown in the figure. Pressurizing the brake compresses the brake springs and withdraws the clamping plates from the brake discs. Standard brakes are furnished with either one or two discs, which are free to move axially.

DBB BRAKES

Eaton’s DBB disc brakes are spring applied and air or hydraulically released. The rotating components’ low inertia makes the DBB ideal for cyclic applications.

Typical applications – Presses, Shears, Bulk Material Handling and General Industrial Equipment

LKB BRAKES

Industrial Clutch LKB brakes are a spring-set, air or hydraulic released brake. This design offers a wide range of torque capacities and release pressures, with total attention given to maximizing ventilation for dissipating large thermal loads. The benefits include longer lining life, stable friction coefficients and lower maintenance costs.

LOW INERTIA CLUTCHES AND BRAKES

Wichita Low Inertia clutches and brakes are air applied, spring released disc style units that develop torque proportional to the air pressure applied. The units are designed to be free from effects of centrifugal force and self-energization. Low inertia start/stop parts reduce acceleration times, which allows more cycles per minute, as well as reducing heat generation.

LUTEX LKB CLUTCH/BRAKE

The Desch Lutex LKB combination clutch/brake (C-B-C) has a low moment of inertia and a compact design. The brake is spring applied, and when sufficient air pressure is applied, the brake disengages, engaging the clutch. The LKB series covers most standard clutch/brake mounting arrangements.

Clutch torque: 184 to 84,820 lb-ft (250 to 115,000 Nm)
