Single Acting Hollow Piston Hydraulic Pull Jack

Single Acting Hollow Plunger Hydraulic Cylinder
Single acting hollow plunger hydraulic cylinder applys toprocessing, maintenanceand tractionwork. The special design of the hollow piston rod makesthe tow bar or cable can pass through the hydraulic cylinder to conduct lifting or jacking operation,commonly used in the work of backward traction and forward extrusion.Equipped with interchangeablesteel reinforced piston base, can also be used for regular lifting operation.Product Features
Single-acting, spring return
Baked enamel finish for increased corrosion resistance;The chrome-plated surface extends the service life of the hollow plunger.
Hollow plunger design allows for both pull and push forces
Collar threads for easy fixturing
Built-in scraper sealreduces contamination, extending cylinder life
3/8 "- 18NPT couplerand dust cap included on all models.Industry Applications
