Reuland RC7-1125-250 Coupling Half - 1-1/8 in. Bore x 1/4 in. Key
Product Details
The Reuland RC7 coupling half, bored 1-1/8″ with a 1/4″ keyway: one hub of an RC jaw-type flexible shaft coupling. Aluminum hub; the Hytrel grommet between the two halves carries the torque, absorbs shock and takes up minor misalignment.

A complete coupling = 2 halves + 1 grommet. Both halves must be RC7; their bores can differ to join two different shafts. Choose the black L9 grommet for service factors up to 1.5, the blue H5 above 1.5.
Reuland or Trilex? Reuland transferred the RC coupling drawings and manufacturing rights to Trilex Fluid Power, which now makes the line to the same design. You may receive original Reuland stock or a Trilex-made part; fit and performance are the same.
Made to order: please allow 3–5 weeks for production. Other bores, metric bores and quantity orders: contact us.
