Designed for confined spaces where standard cylinders cannot be used, the 11.2 ton Capacity, .44 in Stroke, Low Height Hydraulic Cylinder from Enerpac's RSM Series delivers dependable lifting force in a flat, compact form factor. With a maximum operating pressure of 10,000 psi (700 bar) and a 0.44 in (11 mm) stroke, this cylinder is well suited for general lifting and production fixturing applications where vertical clearance is limited.
A single-acting, spring-return design ensures fast, reliable plunger retraction without depending on load weight. The grooved plunger end eliminates the need for a saddle, and two through-mounting holes allow the cylinder to be secured directly to machinery or fixtures. Hard chrome plated steel construction contributes to durability under repeated use, while a baked enamel finish provides corrosion resistance. The unit ships with a CR400 coupler and dust cap included. At 3.1 lbs (1.4 kg), it is easy to position and reposition on the job.

tight spot job here. How short is that RSM100 when it’s collapsed, and how much lift do you really get out of it?

Space is the whole point with this one. It’s a low height, pancake-style cylinder with a short 0.44 inch stroke, so you only get about 0.44 inch of lift.

spring return on this thing actually work good, or does it need the load weight to pull the plunger back down?
Answer by: Customer Support on Dec 6, 2025, 11:44 AM
Built right into the cylinder is a return spring that retracts the plunger on its own. You don't need the load sitting on top of it to bring it back down, which is a real advantage over a lot of other low-profile cylinders that depend entirely on gravity and the weight of whatever you're pushing against. Faster cycle times, more consistent operation.
