Rated for 48.1 tons of force at 10,000 psi (700 bar), this low-profile cylinder is built for lifting and fixturing applications where vertical clearance is restricted. A 0.63 in (16 mm) stroke and 3.5 in (88.9 mm) bore diameter are packaged into a flat, compact body with straight sides that remain stable in both vertical and horizontal orientations.
The Enerpac RSM-500 includes a single-acting spring return mechanism, eliminating the need to rely on load weight for plunger retraction. Two through-mounting holes allow the cylinder to be clamped directly to machinery or tooling fixtures. The hard chrome-plated steel plunger features a grooved end that does not require a saddle, and a baked enamel finish provides corrosion resistance for industrial environments. A CR400 coupler and dust cap are included. At 15 lbs (6.8 kg), the unit is manageable for repeated repositioning on the shop floor.

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.
