OCSC series SUS clamping type oldham shaft coupling. We are manufactuer offer shaft bore:3,4,5,6, 6.35 ,8,9, 9.525 ,10,11,12, 12.7 ,14,15,16,17,18,19,20,22,24,25,28,30,32,35 mm
1:Adjustable ring made of aluminum bronze. High torque.
2:Sliding design,large error adjustment,more effective compensation of radial and angular deviations.
3:Sliding design more effective compensation of radial and angular misalignment.
4:Clamp type(Clamping).
