Couplings, Shafting & Conveyer Belts

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

MASKA 4-Flex couplings 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.

4-flex insert enables these couplings to provide good parallel and angular misalignment capability, dampen vibration and shock, and handle medium amounts of torque.  A complete coupling consists of two hubs, one insert (spider). Hubs are steel and ductile iron.  Tires are natural rubber. Inserts are made of: Standard Black material (Rubber) Nitrile Temp Range -40 to + 212F. Other insert materials are: Orange –Urethane Temp Range -30* to +160 and BEIGE- (Hytrel) Temp Range -60* to + 250 F excellent for chemical resistance, Bronze (Gold color) Temp Range -40 to + 450 F. We show only the standard black inserts in the 4-flex section please contact us if you would like a quote on the orange or beige or bronze inserts.

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. If lubrication is required contact us we can provide a special quote for a cover.
