Rigid coupling

shafts

This bolt coupling is a rigid coupling. It is made of two halves, which are cast iron grade GG25 connected by means of bolts. It is maintenance and lubrication free. Additionally, its construction prevents fretting corrosion and allows for easy mounting and dismounting. The bolt coupling is designed to connect horizontal shafts with similar diameters. The indicated torque values in the specification document refer to couplings without keyways. To transmit higher torques it is possible to machine keyways by following DIN 6885/1. The values of the torque have been calculated with a coefficient of friction equal to 0,15 and with a screw tightening torque according to the indicated value (DIN 912 - 8.8).
