RSM50 45 kN Capacity, 6 mm Stroke, Low Height Hydraulic Cylinder

Enerpac RSM50 is a compact, low-profile hydraulic cylinder engineered for high-force applications in extremely confined spaces, such as under heavy machinery or in production environments where clearance is minimal. Delivering a 5-ton (45 kN) capacity over a 6 mm stroke, this single-acting, spring-return model operates reliably at up to 10,000 psi, featuring a flat design with integrated mounting holes and a grooved plunger for enhanced efficiency and safety in industrial lifting and pushing tasks.
