Double acting, for positive retraction.

Hard chrome plated high quality steel plungers.

Plunger wiper reduces contamination, extending cylinder life.

The exclusive guide Ring is designed absorbs eccentric loading without galling cylinder parts,reduces wear and extending life.

Built-in safety valve prevents accidental over-pressurization.

Special painted surface to increase corrosion resistance.

Easy fixturing with base mounting holes.

All model include quick couplings (NPT3/8"-18) and dust-proof cap.

Removable hardened saddles protect plunger during lifting and pressing.

According to different work environment, special cylinder could be customized.

Flow control one-way check valve (optional):

To prevent the Hydraulic Cylinder from retracting in an instant and realize jacking at any position,
