COUPLING TYPES
Semi-Bridge Couplings
- Small non-threaded bridge in the center.
- Steel cannot thread past bridge area.
- Smaller diameter steel end portions fit together in the center bridge area of the coupling.
- Semi-bridged couplings are most suited to
high-torque machines. - Most rope and HM threaded couplings are
semi-bridged. - Best energy transfer.
Full-Bridge Couplings
- Eliminates the potential for the coupling to creep along the threaded joints.
- Typically used in surface applications.
- Better uncoupling characteristics and tends to
maintain tighter joints. - Less chance of jamming.
Adapter Coupling
- Use when changing from one thread type or
size to another and are typically required only in special circumstances.
