tight spot job here. how short is this cylinder and how much travel do you actually get
Answer by: Customer Support on Apr 10, 2026, 7:58 PM
For space-limited lifts, this RSM500 is a low height cylinder with a short stroke. It has 0.63 in of stroke, so you get just over a half inch of lift per cycle.

Got a tight spot on a press fixture where nothing else fits, does this thing have mounting holes so I can bolt it down proper?
Answer by: Customer Support on Nov 29, 2025, 5:18 PM
Two through mounting holes are built right into the cylinder body, so bolting it to a fixture or clamping it onto machinery is pretty straightforward. The flat sides help it sit stable whether you're running it vertical or horizontal, which makes fixturing a whole lot easier in tight setups.
