Couplings => Steel Couplings => Chain Couplings

Chain Couplings

A very basic coupling design that is capable of withstanding a lot of misalignment while still transmitting a large amount of torque. While this is a very old style of coupling they are still in used in many applications today.

Chain Coupling

 

Roller chain couplings have a torque capacity in excess of the torque normally transmitted by shafting which falls within the coupling bore range. Select the smallest coupling which will accommodate both shafts. For reversing operation, shock or pulsating loads, or other severe operating conditions, select the next larger coupling.
A cover should be used to assure maximum service life, particularly if the coupling operates at high speeds or under moist or abrasive conditions. For proper lubrication, fill the space between the cover and the coupling with soft to medium consistency bearing grease.
