Ratchet Clutches


Lowell ratchet clutches are designed from standard bodies, gears, pawls, and springs. Forces are applied in an optimum between the solid steei gear and hefty pawl so that loads are in compression rather than in standard shear. Gears are a low carbon steel. Rugged tooth design has large contact area with pawl.


Roller Clutches

For applications demanding precise motion control

The simple construction of the Roller Clutch results in an easy-to-produce one-way clutch device that saves money for the user or OEM. Overrunning clutches are also known as free-wheeling or one-way clutches. In these roller-ramp clutches, engagement occurs with a wedging of the rollers between the inner cam and the outer housing. Torque capacity is nomially limited only by the contact stresses between the parts. Standard keyways are per ASA B17. 1.
