German Sealmaster coupling Sealmaster model Sealmaster price

Sealmaster couplings connect two flanged half-couplings to their respective shafts using standard parallel keys, and then bolt the two half-couplings together into a single unit to transmit motion and torque. This type of coupling has two main structural forms: (1) alignment of the two shafts is achieved by bolts in reamed holes, with torque transmitted through compression and shear on the bolt shanks; (2) alignment is achieved by 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 by the two half-couplings
