Rigid Couplings
GB RM Rigid couplings are used to rigidly connect two shafts. Rigid couplings are often used to facilitate
ease-of-maintenance or simply to aid machine assembly. TaperFit bushes provide a secure fit on the driving and driven shafts, ensuring installation and removal is simple.
Selection Procedure
1. Select a size of RM coupling to fit the larger of the driving or driven shafts.
2. For severe applications, select the next size up RM coupling.
NOTE:
HF or FF assemblies can be used on horizontal shafts, only FF assemblies are to be used on vertical shafts.

Ordering instructions

• GB Couplings require GB Bushes which must be ordered as separate items (specifying bush size and the required bores)
