RLT40 43 kN Capacity, 17 mm Stroke, Low Height Multi-stage, Telescopic Hydraulic Cylinder

Enerpac RLT40 is a compact, low-height 2-stage telescopic hydraulic cylinder ideal for precise lifting and positioning in extremely confined spaces, such as machinery alignment or tool fastening. Delivering a maximum capacity of 4.8 tons (43 kN) over a 17 mm stroke, this single-acting, load-return model operates at up to 10,150 psi with nitrocarburized high-alloy steel for superior corrosion and wear resistance, ensuring safe and efficient performance in industrial environments where traditional cylinders cannot fit.
