Reli-a-Flex®

The Reliance Technology Reli-a-Flex® Couplings range was developed by engineers for engineers. Reli-a-Flex® Couplings are flexible shaft or beam couplings. They are suitable for use in complex environments.

A Reli-a-Flex® Coupling is an aluminium alloy (grade 7075-T6), one piece configuration, which has been designed in-house at Reliance to provide very smooth transmission of motion, high torsional stiffness, low bearing loads, and long life. The slot pattern was developed after many months of analysis and test to provide the best balance between zero backlash, torsional stiffness and low bearing load, whilst attaining an operational life in excess of 50,000,000 cycles at rated load and 80% offset. With two sets of identical slots, the Reli-a-Flex® flexible shaft or beam coupling is constant velocity by design and handles angular, parallel and axial offset. Available in sizes from 6 to 40 mm diameter and allowable speeds up to 70,000 rpm, our Reli-a-Flex® couplings provides a very reliable one-piece coupling design.

At Reliance, we believe that the performance of a machine is only as good as the connections of its shafts. Reliance is fully aware of the importance of the shaft coupling and that they are often a critical part of the drive system. The Reliance Technology Reli-a-Flex® Couplings range has been carefully designed and tested to provide trouble free operation over many millions of cycles.
