Non-Round Rod
Cylinders

Designed for systems where no rod rotation during stroke can be tolerated. Resistance to torsional loading is awesome (up to 5000 lb/in with the 1" ( rod and up to 15,000 lb/in on the 2"!). Well-suited for machine tool applications wherein a part needs to be held exactly in place despite forces acting on it to cause rotation.
