Type DC elements can be used as either pressure actuated clutches or brakes. They are available in single and multiple disc designs.

Pressurizing the cylinder causes the piston to clamp the friction disc assemblies between clamping plates. External springs ensure positive disengagement.

Type DC elements are available in five basic disc sizes with static torque ratings to 2,061,000 lb.in (233.000 N.m). Element sizes are indicated by the number of friction discs and by the disc diameter in inches. For instance, size 225DC has two friction discs 25 inches in diameter.
