This RC040708 drawn cup roller clutch with a plastic cage transmits torque between the shaft and housing in one direction and allows free overrun in the opposite direction. The drawn cup outer steel shell provides a small cross-section for use in restricted spaces, and serves as a raceway for the rollers. The clutch has molded acetyl resin polymer cage with an integral leaf spring for each roller, allowing continuous operation up to 200 degrees F (90 degrees C). The rollers are made of through-hardened, high-carbon chromium steel for heat tolerance and durability, and the clutch comes packed with lithium soap grease. This drawn cup roller clutch is used in various applications, such as athletic equipment, paper towel dispensers, office machines, and appliances, among others.
