Roller-Chain Shaft Couplings
With a rugged roller-chain design, these couplings provide excellent torque and angular misalignment capacities. Lubrication is required. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.. A complete coupling consists of two hubs and one roller chain (each component sold separately). Complete couplings meet ANSI B29.23M-1995.

Couplings in roll forming mills
Precision couplings were required at each roller station to connect the rollers on the assembly stands to the series-connected gearmotors. The possible dimensions of the couplings were based on the conditions in the rolling stand: they could not be longer than 145 millimeters with an outside diameter of 200 millimeters. At the same time ...
