Types and sizes of centering coupling
Patented
Overall line 0f centering couplings is divided into design concepts and has 4 types:
- large-diameter centering coupling (LD CC);
- middle-size centering coupling (MD CC);
- small-diameter centering coupling (SD CC);
- middle-size centering coupling “Snare” (MD CCS).
