BBC-29 Mechanically Actuated Ball Bearing Clutch

BBC-29 Mechanically Actuated Ball Bearing Clutch

The model BBC-29 clutch combines the ease of direct electromagnetic actuation with the quick response and high torque offered by wrap spring technology. This improved clutch design features a ball bearing drive and a new magnetic circuit to enhance its performance and efficiency and greatly increase its life. Bearing life effectively determines clutch life. Clutch performance has been significantly improved by replacing the sleeve bearing, commonly used in this type of clutch, with a shielded, pre lubricated ball bearing. Life expectancy may now exceed 50 million cycles.
