Hard Chrome

A hard chrome cylinder bore and piston rod maximises corrosion-resistance and cylinder life.

Bronze Overlay

The piston bearing area is bronze overlaid to reduce scoring and increase service life.

Steel Base Plate

All cylinders incorporate a bolt-on, removable steel base plate for extra protection.

Threaded Fit Smooth Saddle

A threaded fit smooth saddle prevents piston rod damage. Optional TSH
threaded saddles also available.

Return Spring

The return spring is sized to ensure efficient piston rod return and maximum spring life.

Gland Nut

Low friction coating on the gland nut withstands full dead end loading.
