Hydraulic Cylinder Piston
Hydraulic cylinder piston, in 34 sizes across a Ø32–250 mm bore range. Used in manufacturing and rebuilds.
The part that turns pressure into force. Force is proportional to piston area: the full area works on extension, the area minus the rod section on retraction.
Sizes are written as bore × rod diameter: 100x50 means a Ø50 mm rod in a Ø100 mm bore.

If you do not know the size, bring the part in and we will measure it. Prices are given on quotation.
Seal and gasket set
Every size on the list has a matching seal/gasket set. In a rebuild, if the part itself is sound, usually only the set is replaced — give us the size and we will pull the right one.
