German CSK 25 coupling, CSK 25 model, CSK 25 price

CSK 25 couplings connect two flanged half-couplings to their respective shafts using standard parallel keys, and then bolt the two half-couplings together 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 via compression and shear on the bolt shanks; (2) achieves alignment by mating a spigot on one half-coupling with a recess on the other. The bolts connecting the two half-couplings can be grade A and grade B standard bolts, with torque transmitted through the frictional moment at the mating surfaces of the two half-couplings.
