The TINY-CLUTCH D series represents a range of miniature rollers and cam type, one way clutches built according to specific equipment requirements, eliminating any loose parts. These units are often used to override the input of a driven member, load backstopping and conversion of oscillating motion into rotary motion. Based on the proven cam and roller principle, these models offer long and problem free operation (no chance of jamming in the free direction), with almost no backlash and high free-wheeling speeds. The rollers feature spring activation, firmly fixed and centered in a drilled pocket. The housing is also equipped with a knurled knob, permitting pulley, gear or sprocket installation, while the cam is attached to the shaft via screw, pin or key. All components are made out of hardened steel.
