Universal Joints

A Universal joint is a mechanical device used to connect two shafts whose axes are not aligned angularly. Available in alloy steel, stainless steel or special materials, the single joint configuration can accept up to 25 degrees of angular misalignment where as the double joint designs can accept up to 50 degrees of shaft misalignment.

Model designs can include needle bearings, hardened bushes or plain pin, depending on torque and speed requirements. Bore sizes from 4mm to 50mm as standard. Other bore sizes including keyways are available on request.

Universal joints are particularly efficient at transmitting torque through greater shaft offset angles than a standard shaft coupling design can. ABSSAC supplies miniature and industrial sizes, using standard cast model numbers up to specifically designed machined units.

Recently, one of ABSSAC’s Universal Joint products has just passed extensive testing connecting an electric motor to a compressor for use in large cold store. As part of a national refurbishment, 303 Stainless steel was utilised to accept both the arduous environmental requirements, but also a possible static torque of up 9150Nm (81000lbin).  Each U-Joint was 100mm (4”) in diameter and 270mm  ( 10.6”) long and capable of accepting up to 35 degrees of angular shaft offset.  ABSSAC was chosen as the preferred supplier on cost, delivery and performance.  As standard we offer the following types of universal joint that can accomodate bore sizes from 4mm to 50mm bore sizes. Other bore sizes including keyways are available on request.
