Specifying the right flexible shaft coupling for an application can be a technical challenge for the engineer, particularly as there are also so many designs on the market.  Shaft size, torque capability, angular and parallel shaft misalignment, not to mention material and attachment, all add to the myriad of parameters that narrow down choice.

At Abssac, we pride ourselves on our experience in the specification of shaft couplings whether they are miniature or Industrial. We have a 30 year plus supply chain behind us, to ensure correct product specification.

A universal joint is a mechanical device that allows two shafts not in line with each other limited freedom of movement in any direction whilst transmitting rotary motion.

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.

Pascal discovered the principle. ETP put it to work. ABSSAC is the appointed United Kingdom distributor for the entire product range of ETP hydraulic clamping hubs and bushes.

All ETP products consist of a double-walled hardened steel (in some cases stainless steel) sleeve, filled with a pressure medium. In the product flange there are one or more screws and a piston with seals for the pressure setting. When the pressure screw is tightened an even and moderately high surface pressure is created against the shaft and hub, causing the locking effect. The self-contained product allows this procedure to be repeated many times.

Whether the hubs are to be removed or repositioned, mounting and dismantling is done in less than a few seconds.

Clutches for industrial use are available in three basic designs, giving optimum performance.

The Rota-Cam Clutch utilises the easily installed Roto-Cam®, which completely eliminates external, separately mounted fulcrums, yokes, levers or trunnions and permits a simple, clean compact control system for direct or remote, manual or powered actuation. Roto-Cam provides smooth easy engagement typical of a spring loaded clutch plus a positive, over-centre 'lock-in'. The clutch can be 'inched' or 'Jogged' for complete operator control.
