RSM

RSM Series hydraulic cylinder is a single-acting, spring-return ultra-thin (low-profile) hydraulic cylinder built for use in confined spaces where standard hydraulic cylinders do not fit. Its flat, compact body delivers full rated force from a minimal installed height, so it works inside narrow clearances on jacking, alignment and lifting jobs. A hard-chrome-plated steel plunger, grooved load face and powder coat finish make it reliable in harsh site, workshop and outdoor conditions, and every model ships with a quick coupling and dust cap for immediate hook-up to a pump.

Optional Attachment

The MDW square drive hydraulic torque wrench range spans 112 to 72,000 N·m in 11 standard models, with bolt capacity from M14 to M125. A single tool family covers light flange work through heavy structural bolting, so your crew standardizes on one platform with common pumps, hoses and high-strength sockets instead of mixing tools from different suppliers.
