400 Series single sprocket self contained automatic centrifugal clutches.
Popularity of these four models allows greater production economics without sacrifice of quality....and we pass these savings on to you. The 400 Series clutches have more contact surface than most competitors. Almost 3 3/4 square inches of steel friction material engagement shoe surface assures positive pulling power as long as the RPM is in full contact range. They have continued performance even when they were partly destroyed in torture tests. Bearings have been almost completely worn through by sand and they continued to function.
