Couplings

Roller-chain shaft coupling allows excellent torque and angular misalignment capacities. All coupling have a key with standard ANSI keyway dimensions for more secure hold on keyed shafts. To create a complete coupling please order two sprocket hubs and one roller chain.

Jaw couplings are manufactured with a finished bore and are machined from bar steel with standard key seats and hollow head set screw.

MD Flex Flyer can take on parallel, angular, and axial misalignment, plus dampen vibration and shock.  There's no metal-to-metal contact, so there's no need for lubrication.  Connect couplings to your shaft via standard ANSI keyways (except where noted) and four set screws.  For a complete flexible coupling, you need to order two hubs and one rubber element. See keystock in shafting section to order keystock.
