For use with FFR (Flex-Rigid) or FRR (Rigid-Rigid) couplings
Exposed bolts E are also the standard design for this coupling
Exposed bolts E are the standard design for this coupling
The FFR Type coupling consists of one flex hub, one rigid hub, one sleeve, and one accessory kit
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
The FRR Type coupling does not accommodate for any angular misalignment.
