Cylinders

Hydraulic cylinders are powered by hydraulic fluid which has been correctly pressurized and consist of a cylinder barrel, contained in which a piston operates. The barrel on one end of the cylinder is closed off and the piston rod emerges from the other end of the cylinder. the cylinder is divided inside into two chambers, the head end contains the piston rod and the tail end is capped off.

Our bespoke and standard cylinders have been selected to cater for a range of applications in many different fields of operation. We can cater for a number of custom builds and offer a range of cylinder additions and options and are always available to aid you with advice and tips on the correct cylinder for your application.

Cylinders typically come in a range of sizes and functions including single acting and double acting variants. In single acting cylinders, the working fluid acts on one side of the piston, relying primarily on its load, momentum as well as springs to force the piston back in the other direction.

Double acting cylinders have a port at both ends which can move fluid in either direction for extension and retraction movement. It is the most popular of the two main types of cylinder due to its versatility in its many potential uses. 

Bespoke cylinders can be used for a range of tasks and come in variants such as Servos for joining turbine blades to turbine hubs; Large bore cylinders for sub-sea cabling and Thru-rod, Thru-bore cylinders to operate robotic grab hands in manufacturing plants.

We have the capability to fix and service cylinders in-house and can supply the components for this process from our large off-the-shelf range of stock.


Popular applications for our cylinders include:

  • Fatigue testing equipment
  • Marine applications
  • Materials handling
  • Aircraft engine componentry
  • Pipe manipulation equipment


  • Why choose Hydraproducts as your component supplier?
  • Manufacturers

Hydraproducts has a large stock holding of components we are able to support irregular customer requirements. If you have regular needs then we are happy to hold bonded stock to smooth out production/supply fluctuations.

Supporting our customers with the comfort that our engineers have been using these components to build hydraulic systems in our own workshops for over 15 years. Our Technical Sales engineers can help and advise on product choice as well as identifiy and cross reference a wide variety of other hydraulic equipment manufacturers.

Key manufacturers 

OMT - Based in Italy, OMT has become a world recognized manufacturer of Hydraulic components. A recent acquisition of Luen, Hydraulic cartridge Valve manufacturer, has strengthened the group within mobile and industrial markets. 

OT - With a engineering pedigree in Italian gear pump manufacturing, this company produces some the of the finest Aluminium hydraulic Gear pumps available today. They are customer focused with a very reactive production philosophy.

TEC - Tec motors have become the largest reseller of AC induction motors in the  UK. Hydraproducts has fitted the TEC (TECHTOP) motors to our power packs and power units for over 15 years, so we know the quality is well suited to this market palce.


  • More about Micro Power Packs
  • Typical Applications

The HPU micro power pack has a single acting hydraulic circuit, the check valve and solenoid valve hold the cylinder load up. A high quality hardened steel check valve insert ensures low leakage and excellent load holding. Versions with Normally open/closed solenoid check valves and low noise check valves are available.

All of these micro hydraulic power packs have a precision engineered aluminium manifold that houses the hardened steel valves. A carefully developed micro hydraulic pump gives pressures up to 200bar. Each manifold has an integrated 90 micron filter element, ensuring all micro hydraulic systems are protected and give a long service life.

To drive the hydraulic pumps we offer DC motors from 150 to 800Watt, in 12V and 24VDC. 150 and 250Watt Fractional Horsepower AC motors as well as standard IEC frame AC motors from 0.18kW to 0.37kW.

Pump sizes range from 0.17cc to 1.48cc/rev.

Tanks from 0.1 to 1 Litre, all of which can be in vertical (tank uppermost) or horizontal orientation.

Typical applications include :- 

    Mobility lifts where Wheelchairs are lifted from vehicles
    Micro power packs for through floor lifts.
    Door and gate opening actuators

Hydraproducts offers its worldwide OEMs and distributors reliable products through design and manufacturing expertise. The quality of in-house design, manufacturing and experience in micro hydraulic power units ensures a match to your requirements.
