Semi-Bridge Coupling
- Small non threaded central bridge
- Most suited to high torque machines
Full-Bridge Coupling
- Used for surface applications
- Maintains tighter joins
- Better uncoupling characteristics
- Best suited to machines with independent rotation
Adaptor Coupling
- Useful when there is a need to change from one thread size or type to another.
- Typically used in special circumstances
