With over 40 years’ experience at Derek Lane, our team are well versed to advise on all hydraulic actuator requirements from off-the-shelf actuators to bespoke actuator design and manufacture. We also carry out high quality hydraulic actuator repair, including free actuator assessment.

With safety at the forefront of all hydraulic equipment, both bespoke and off-the-shelf actuators are manufactured with hard chrome steel piston rods. Specialist seals can be supplied according to the application and mounting configurations can be accommodated, including cylinder trunnion, rear clevis, flange mounted and many more dependent upon application. 

All hydraulic actuators that leave our premises in Devon are tested and ready for operation.

We manufacture and source a range of actuators, with specifications ranging from:

  • Tie-rod hydraulic actuators
  • Bolted hydraulic actuators
  • Electro-hydraulic linear actuators
  • Double-acting hydraulic actuators
  • Stainless steel options
  • Seals specified to suit application

High Quality Actuator Repair

Our hydraulic engineers have experience with many varieties of actuator repair requirements, so any repair is possible.

The most common repairs are often simple seal replacements; hydraulic seals are the most susceptible part of an actuator and suffer from wear and tear, leading to leaks and inefficiencies in operation.

We manufacture and repair hydraulic rams to suit the individual requirements of our clients. Here is a selection of the range of products we provide repairs for:

• Single acting
• Double acting
• Subsea and offshore
• Telescopic
• Displacement
• Rod feed
• High pressure
• Trunion mounted
• Spring return

No matter where you are located in the UK, we are here to help. All repairs are carried out by our teams to stringent processes and we guarantee 100% customer satisfaction. You will receive your repaired hydraulic actuator fully tested and ready for installation.



This range of hydraulic cylinders, also referred to as mill cylinders, are typically used in heavy-duty arduous applications. The cylinder dimensions conform to ISO 6022. This range of cylinders is available in bore diameters from 40mm bore to 320mm bore, with a wide range of options which include internal linear transducers and built-on manifold valve packages.

Tie Rod

Conforming to ISO 6020/2, this range of tie rod construction hydraulic cylinders is mainly used in machine tool and process machine applications. These cylinders are directly interchangeable with many other manufacturers of tie rod cylinders. They are available with bore diameters from 25mm bore to 200mm bore and can be supplied with or without end-of-stroke cushioning.


A medium duty range of welded construction hydraulic cylinders, available as both double acting and single acting, with bore diameters from 25mm bore to 250mm bore. Series T6W cylinders are available with a wide range of mounting options and can be customised to customers’ requirements.


Series T6R rotary actuators can be supplied as single or double rack versions, double acting or fail-safe. A wide range of sizes are available, giving many combinations of torque and pressure outputs. The actuators can be supplied with almost any desired angle of rotation, special heavy-duty versions are available and all styles can be supplied with position monitoring, end-of-stroke cushioning and a choice of male and female drive outputs.


Actuators are mechanical devices that convert energy into motion.

An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example, by opening a valve. In simple terms, it is a ‘mover’.

Hydraulic actuators comprise a piston that moves in the inside of a hollow cylinder.

There is no difference between an actuator, a cylinder or a ram.

They were traditionally called actuators, as their primary job was to move objects. As the needs of industry and the scope of power that can be generated increased, they also become known as rams.

The name hydraulic cylinder was derived from the fact that the product itself contains a cylinder (or hollow box) that houses the mechanical operation. Nowadays, hydraulic cylinders have become a more common name for hydraulic actuators.

There are three forms of actuation: hydraulic, pneumatic and electrical.

Very simply, if you are looking for power and need to exert a large force, then you will usually need a hydraulic actuator. Hydraulic actuators are typically 25 times more powerful than pneumatics and are often used in industrial applications. Hydraulics are ideally suited for trucks and heavy equipment applications.

If you need precision and accuracy when moving things, then you will generally need an electric actuator.

If you require speed and accuracy, and power is not a factor, then you will generally need a pneumatic cylinder.
