F Type Rigid Hubs, Inch (Imperial) Bore & Keyway - Exposed and Shrouded Bolt Designs

For use with FFR (Flex-Rigid) or FRR (Rigid-Rigid) couplings.

The FFR Type coupling consists of one flex hub, one rigid hub, one sleeve, and one accessory kit. Exposed bolts (E) are the standard design for this coupling, though shrouded bolt (S) designs are available upon request through size 5.5. The FFR Type has a max angular misalignment of 1.5 degrees (1.5 degrees per gear mesh).

The FRR Type coupling consists of two rigid hubs and one accessory kit. Exposed bolts (E) are also the standard design for this coupling, though shrouded bolt (S) designs are available upon request through size 5.5. The FRR Type coupling does not accommodate for any angular misalignment.

For larger torques, consider the FHD Type gear coupling in sizes 10 through 30.
