Industrial CSK30-M-C5 One-Way Sprag Clutch Bearing

The Stieber CSK30-M-C5 is a shaft-mounted one-way sprag clutch bearing that transmits torque in a single direction while allowing free rotation in the opposite direction. It combines a sprag clutch with a ball bearing in a hardened steel assembly and is grease-lubricated for reliable power transmission. With a 30 mm bore (CSK series), it supports overrunning, indexing, and backstopping in industrial drives such as conveyors, packaging machinery, indexing equipment, printing presses, textile machines, and other power transmission systems. Common replacements include Stieber CSK30-PP, INA HF3020, and Ring-spann FXM Series backstop clutches.
