Hydraulic Cylinders

Our factory has the capacity to design and produce or repair hydraulic and pneumatic cylinders up to 4 tonnes in weight and over 30 feet in length. Our design, manufacturing and repair capability covers a wide range of types including tie bar, welded – construction, screwed and welded, single acting, displacement and multi stage. We will also produce customers’ own designs to meet their individual specifications, the latter being more common.

If you are experiencing recurring faults or failures – our design team can evaluate your application and where necessary re-engineer your cylinders to remove the problems. Our machine shop has a combination of manual and CNC machines, which allows us the flexibility to produce batch runs of cylinders and components or one off specials competitively.


Hydraulic Cylinders

We carry a wide range of material stock to offer the best turnaround possible on repairs. Our honed barrel stock ranges from 25mm bore to 250mm bore in various wall thicknesses depending on the pressure capability required. Chromed rod in stock ranges from 8mm to 160mm, and most materials are duplicated in imperial sizes also.

Stainless steel honed barrel is also available from stock – together with various sizes of stainless steel and induction hardened rod material for the marine, plant and food industries.

A hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. It has many applications, notably in construction equipment (engineering vehicles), manufacturing machinery, and civil engineering.

Hydraulic cylinders get their power from pressurized hydraulic fluid, which is typically oil. The hydraulic cylinder consists of a cylinder barrel, in which a piston connected to a piston rod moves back and forth. The barrel is closed on one end by the cylinder bottom (also called the cap) and the other end by the cylinder head (also called the gland) where the piston rod comes out of the cylinder. The piston has sliding rings and seals. The piston divides the inside of the cylinder into two chambers, the bottom chamber (cap end) and the piston rod side chamber (rod end / head end).

Flanges, trunnions, clevises, and lugs are common cylinder mounting options. The piston rod also has mounting attachments to connect the cylinder to the object or machine component that it is pushing or pulling.
