Telescopic Cylinder query
Telescopic Cylinder query
(OP)
Hi Everyone
I'm having a telescopic hydraulic cylinder installed on a machine, the cylinder will be used to push a piece along a roller. It will have a rectangular block attached to the end of the cylinder.....My question is this, when pushing will the cylinder rotate ? will i need top have a stabiliser guide fitted ?If it rotates the block will snag on the rollers
Thanks

If the bore of the cylinder was "honed" as part of its manufaturing process then the honing machine will invariably leave microscopic scratches on the bore just like the long shallow helix down the bore of a rifle. When you pressurise either cylinder volume the piston seals become "energised" and press against the inside of the bore. As the cylinder strokes, the seals tend to key into the scratches and make the piston (and rod) rotate. You might find that the cylinder rod consistently rotates one way when extending and then the other way when retracting: effectively mimicing the movement of the original honing machine.

If you don't want it to rotate...guide it!!!
