Industrial Ratchet Freewheels
and Adaptors

CROSS+MORSE

Industrial Ratchet Freewheels provide positive one-way drive with high torque
capacity within a small unit. A ratchet and pawl mechanism is used with
materials and heat treatment selected for a long operating life, with safe,
positive transmission. IRF’s are suited to low speed (up to 150 r.p.m.) overrun
applications where shock loads may be encountered, such as Agricultural
machinery. Standard stock units are available in two configurations; as
standard sprocket for 1/2 inch pitch chains, or with a drilled flange to
fit conveyor rollers, pulleys, or wheels. Standard units have threaded
bore to cycle standards, but a range of Adaptors enable fitting to
keyed shafting. IRF clutches are also stocked in part-assembled
condition for reworking to custom design, including finish parallel
bore and keyseat. Many special Industrial Ratchet Freewheels
have been manufactured to meet customers’ requirements with
torques over 1,000 Nm.
