PB-C Drum Coupling
PB-C Drum Coupling

The PB-C drum couplings are composed of two cast iron hubs onto which pins fitted with rubber bushes are mounted:
The rubber bushes are vulcanized onto wear-resisting brass liners which are mounted on the pins with a clearance. This allows them to rotate freely and move slightly lengthwise. The stress exerted onto the bearings is thus significantly reduced.
