BMSH-306, 30 ton Capacity, 155 mm Stroke, Single Acting Hollow Cylinder
RC-TRIO is the next generation of the legendary Enerpac RC-Series single acting hydraulic cylinders. These hydraulic jacks include many advanced features to ensure superior durability, versatility, and productivity.
Overview
THE BMSH-SERIES IS A SPRING RETURN HOLLOW PISTON ROD CYLINDER. The hollow piston allows for a rod or cable to be inserted through the entire body length. They can be used in tensioning, load testing and bush extracting and maintenance applications. All RHS-Series cylinders feature a hard chrome cylinder bore and piston rod for maximum corrosion resistance and a bronze overlay piston bearing area to reduce scoring and increase service life. All cylinders incorporate a bolt on removable steel base plate for extra protection.
