- This coupling is the most widely used rigid coupling
- Simple structure, reliable performance, torque delivery, assembly and disassembly. Shaft hole keyway forms provided by GB/T3852-1997.
- GY-based system using hinge bolt hole on the assembly and disassembly without moving along the axial.
- GYS type bump on the tongue, processing convenience, but disassemble to move along the axis.
- Shaft hole pattern can also be a cone.
