Enerpac | 48.1 ton Capacity, .63 in Stroke, Low Height Hydraulic Cylinder | RSM500

Description & Features

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.

Question by: Bobby H on Apr 9, 2026, 8:59 AM
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.
