    Following hot on the heels of the release of the  new MAX RAM range, MOTUS Hydraulics have come up with a commercially viable method of preventing a hydraulic cylinder from rotating. This brilliant innovation was the brainchild of MOTUS in-house R & D Team leader, Professor Richard A McGuffaw. The professor has been heading the rotational project at Motus under lock and key for the past 3 years, as part of the Quadrallipse Project. Previously this would have required special machining and assembly processing making the production costs prohibitive for mass production.

    What MOTUS have achieved utilising specialist machinery is to deform the tube AFTER machining, and the WRC head design makes this possible. As one would realise, it is not an easy feat, and it takes a great deal of patience to screw an oval head into an oval body. As you can see in the photo, the design is very clean and holds the rotation angle to less than 0.23 degrees. Very simple it utilises standard seals, standard shaft, special piston, head and base. In the words of Professor R.A.M- “using the patented Quadrallipse Tool holder on our CNC machines, allows quadralliptical machining, while retaining a conventional round shaft in order to keep costs down, and utilising standard seals.”

    The new Quadrallipse range of RAMS is on sale today only, in a range of sizes from 1.5 – 4 inch bore. Contact sales@motushydraulics.co.nz for more information.
