Cardan Curved Jaw Couplings



Ondrives. Standard style Jaw couplings accommodate minimal radial or angular misalignment between shafts. Cardan Jaw Couplings double the angular capability of standard Jaw couplings and adjust a large amount of radial misalignment. Our Cardan shaft couplings absorb vibration eliminating metal-to-metal contact and the need for lubrication while transmitting torque and rotary motion between two shafts. Our jaw couplings provide zero-backlash performance at speeds up to 34,100 RPM and feature high-quality materials for extended service life. Cardan curved jaw couplings are available in an inch and metric bore sizes, with torque levels up to 1,060 lbs.-in.

Zero Backlash Cardan Shaft Couplings for Motion Transfer Applications:

Ever-Power is a leading designer and manufacturer of high-performance couplings. Our reliable, heavy-duty Cardan jaw couplings are manufactured with top-quality materials and unparalleled engineering for superior performance and long working life. These jaw couplings provide exceptional shock and vibration dampening and are ideal for various motion transfer applications.

Cardan Curved Jaw Couplings with Double the Misalignment Capability:

Cardan jaw couplings are used to couple shafts in various applications, including conveyors, generators, pumps, gearboxes, compressors, and blowers. Our specialty Cardan shaft couplings feature a unique Cardan joint that allows for greater angular and radial misalignment than other coupling models. Our Cardan curved jaw couplings offer double the misalignment capability and exponentially increase the radial alignment capability. Jaw couplings are easy to install and have a fail-safe design for operation even if the elastomer spider fails. This coupling style is ideal for operating environments requiring moisture, oil, or chemical resistance.
