Shakti pulley manufactures pin bush flexible couplings [b-1 to b-11] from 95 mm to 530 mm diameter. These pin bush couplings are ideal for torque from 8.0 to 242 kgm. The pin bush flexible couplings are cushioned drive type, transmitting torque through rubber bushes, which possess excellent capacity to absorb shock. These types of pin bush flexible couplings allow drive in either direction, and require neither lubrication nor adjustment after fitting.
