Linear Actuator Types Explained for UK Buyers
16 August 2026
Discover the main linear actuator types for UK use: 12V, electric, hydraulic, pneumatic, and more. Choose the right one for your project.
What Is a Linear Actuator?
A linear actuator is a device that creates motion in a straight line, converting energy into push or pull force. In the UK, they are used across everything from home automation and agricultural machinery to industrial automation and medical equipment. Understanding the different linear actuator types is essential before you buy, as each offers distinct advantages in speed, force, precision, and duty cycle. The main categories are electric, hydraulic, and pneumatic, each with unique power sources and performance characteristics. In this guide, we focus on what matters to UK users: reliability in our damp climate, availability of spare parts, and compatibility with standard UK power supplies and control systems.
Electric Linear Actuators (12V and 24V)
Electric linear actuators are the most popular choice for UK consumers and businesses. They run on low-voltage DC motors (usually 12V or 24V) and are clean, quiet, and easy to control. In the UK, 12V actuators are widely used in TV lifts, adjustable desks, and solar trackers, while 24V versions suit more demanding applications like agricultural hoppers and industrial machinery. When buying an electric actuator in the UK, always check the IP rating – IP65 or higher is recommended for outdoor use, especially given our frequent rain. Also consider the stroke length, dynamic load, and whether you need limit switches or a feedback signal for accurate positioning.
Hydraulic Linear Actuators
Hydraulic linear actuators use pressurised fluid to generate very high forces – often several tonnes. They are the go-to choice for heavy-duty UK applications such as construction equipment, vehicle lifts, and industrial presses. Hydraulic systems offer excellent power-to-weight ratios and can hold a position without power, which is a major safety benefit. However, they require a pump, reservoir, and hoses, making installation more complex and potentially messy. In the UK, hydraulic actuators are common in agriculture and marine environments, but they are less popular for DIY projects due to maintenance costs. If you need compact brute force and have the budget, hydraulics are unmatched.
Pneumatic Linear Actuators
Pneumatic linear actuators use compressed air to produce rapid, repeatable motion. They are a staple in UK manufacturing plants, packaging lines, and automation cells, where speed and simplicity matter more than holding force. Pneumatics are inherently safe in explosive atmospheres and are driven by a compressor, which many UK workshops already have. They are lighter and cheaper than hydraulic equivalents, but their force is limited by air pressure (usually 6–10 bar). For lightweight, high-speed applications like sorting and clamping, pneumatic actuators are the most cost-effective solution. Just remember to install a water separator, as UK air lines can condense moisture in winter.
Which Linear Actuator Should You Choose?
When choosing between linear actuator types, start by defining your load, speed, stroke length, and duty cycle. For most UK home and agricultural projects, a 12V electric actuator is the easiest to install and control, especially with remote controls or Arduino compatibility. For heavy lifting, choose a hydraulic unit – but budget for a professional installation if you're not confident with fluid systems. Pneumatic actuators suit fast, light automation in a factory or workshop. Also consider the UK climate: outdoor actuators need IP65 or better, and submersible applications are rare but possible. By matching the technology to your real-world conditions, you'll get years of reliable service.
FAQ
The most common linear actuator type is the electric actuator, specifically 12V or 24V DC models. They are widely sold online in the UK, used in everything from TV lifts and adjustable beds to industrial gates and robotics. Electric actuators are preferred because they are plug-and-play, require no extra pump or compressor, and are easy to control with simple switches or controllers.
