Type CH elements are for heavy-duty clutch and brake applications and can be air- or hydraulically actuated. The friction disc packs are for wet or dry operation, and actuation is accomplished through internal shaft and clutch passages. When used as a wet clutch, coolant oil is forced through the friction disc pack from an internal shaft package. Type CH elements are available in six sizes, with torque ratings to 1,038,000 lb-inches. Sintered bronze friction material, operating in oil, provides a low static-to-dynamic torque ratio.
