Completely flexible with crowned teeth
These couplings (fig 1) accommodate a total misalignment of up to 3°. Where the misalignment is larger than 1,5°, however, SKF should be consulted. The couplings can withstand start-up peak moments of two times the stated continuous torque.
By reversing one or both of the hubs, the same coupling can be used for different shaft end separations.
These couplings have efficient O-ring seals and should be lubricated with grease.
