For use with F (Flex-Flex) or FFR (Flex-Rigid) couplings.
The F Type coupling consists of two flex hubs, two sleeves 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 F Type has a max angular misalignment of 3.0 degrees (1.5 degrees per gear mesh).
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).
For larger torques, consider the FHD Type gear coupling in sizes 10 through 30.
