Germany MK4/20/37 coupling MK4/20/37 model MK4/20/37 price

MK4/20/37 coupling connects two flanged half-couplings to the respective shafts using standard parallel keys, and then bolts the two half-couplings together into a single unit to transmit motion and torque. This type of coupling has two main structural forms: (1) achieves shaft alignment through bolts in reamed holes and transmits torque by subjecting the bolt shanks to compression and shear; (2) achieves alignment through the fit between a shoulder on one half-coupling and a groove on the other. The bolts connecting the two half-couplings can be standard bolts of grade A and grade B, with torque transmitted through the frictional moment at the joint interface of the two half-couplings.
