RSM-Series Low Profile Hydraulic Cylinders provide superior durability, safety, and quality in a compact and convenient format. They’re the perfect choice for general lifting and production applications where space is limited.
A low collapsed height, short stroke, and flat sides enable safety and stability in both vertical and horizontal orientations.

RSM-Series Cylinders are a popular choice. Not only for general lifting, but also for production applications. Two through mounting holes in each cylinder make it easy to clamp onto machinery and other fixtures.
Many low-profile hydraulic cylinders rely on the weight of the load to retract the plunger. RSM cylinders are different and include a powerful return spring, which is faster, convenient, and more productive.
The Enerpac RMS500 is a 50-ton low-height, single-acting, spring-return hydraulic cylinder engineered for powerful lifting and pressing in confined spaces. With a collapsed height of just 2.63 inches and a stroke of 0.63 inches, this compact unit delivers exceptional lifting capacity where clearance is limited—ideal for machinery positioning, bridge bearing maintenance, and structural realignment tasks.
Constructed from high-strength alloy steel, the RMS500 features a nickel-plated, corrosion-resistant finish and hardened piston rod for superior durability in tough industrial environments. The single-acting spring return ensures quick retraction after pressure release, while the integral base mounting holes allow for stable and secure placement during lifting operations. The CR-400 coupler and dust cap come standard for compatibility with Enerpac’s 10,000 psi hydraulic systems.
Low clearance capability: With its 2.63″ collapsed height, the RMS500 is ideal for tight work areas under heavy equipment, support beams, or industrial machinery.
Spring return simplicity: Automatic piston retraction when pressure is released improves operational efficiency and reduces setup time.
Compact power: A 50-ton lifting capacity in a short-stroke design provides excellent strength-to-size performance.
Durability: The RMS500’s heat-treated, nickel-plated components resist corrosion and wear, ensuring long service life in demanding environments.
Universal coupler compatibility: Equipped with an Enerpac CR-400 coupler for quick and reliable hydraulic connections to Enerpac pumps and hoses.
Short stroke: The 0.63” travel is designed for fine adjustment or small, precise lifts rather than large movement.
Single-acting return: Relies on an internal spring for retraction, not hydraulic pressure, which may be slower in certain positions.
Load alignment: As with all low-height cylinders, ensure loads are well-centered to avoid side-loading damage.
System match: Operates at up to 10,000 psi — use only with compatible hoses, fittings, and pumps.
Machinery alignment or leveling in restricted spaces
Bridge and structural bearing maintenance
Heavy equipment positioning where clearance is minimal
Industrial repair and maintenance jacking operations
Always position the cylinder on a solid, level surface for stable load transfer.
Use hoses and fittings rated for 10,000 psi service pressure.
Avoid lateral loads on the piston—keep load aligned with the cylinder centerline.
Inspect regularly for wear, leaks, or damage; even though the cylinder is corrosion-protected, heavy-duty use warrants routine maintenance.
Center hole cylinders typically require a compatible hydraulic pump, hoses, pressure gauge, and appropriate threaded adapters or fixtures.
A hydraulic low profile cylinder is a compact lifting cylinder designed for restricted-clearance applications.
Center hole cylinders feature a hollow bore that allows force to be applied through threaded rods or cables, enabling pulling and tensioning applications that standard cylinders cannot perform.
Yes. They are frequently used in engineered lifting projects.
