Reli-a-Flex precision couplings: accuracy under misalignment

The patented design slot feature allows Reli-a-Flex couplings to maintain the centre piece angle and constant pivot length, even under significant misalignment conditions. Alternative one piece couplings often resemble the Reli-a-Flex but may have a slot pattern where the pivot points are able to move in and out, causing the centre piece angle to deviate. Reli-a-Flex couplings however, have been tested at 80 per cent maximum offset for 50,000,000 cycles; producing bi-directional error up to six times less than that of other four beam spiral couplings.

Uniform stress levels, combined with accurate angular rotation and a constant pivot length, makes the Reli-a-Flex one piece flexible shaft coupling suitable for design engineers working in the printing, medical and scientific instrument sectors where it is necessary to maintain predictable and accurate transfer of motion.

Available as a standard catalogue product with outside diameters ranging from 6mm to 40mm and manufactured from aircraft grade aluminium alloy, Reli-a-Flex flexible shaft couplings can also be selected by visiting the online store where a custom coupling can be created to match specific design applications.
