ENERPAC Actuators, hydraulic cylinders 

ENERPAC hydraulic cylinders 

Actuators in the offer hydraulic cylinders commonly referred to as actuators. Actuators designed for hydraulically driven machines and devices - intended for lifting, pressing, and others. We carry cylinders from the series RC ( single-acting ), RCH cylinders ( single-acting with return spring and hollow plunger).  Most cylinder models from the RCH series are equipped with a CR-400 coupler. Some models feature an AR-630 coupler, as well as a 1/4” NPTF connection or FZ-1630 reduction. Most cylinders have smooth saddles. Selected cylinder models are available in a set, which includes the cylinder, pressure gauge, couplers, hose, and pump. If you need a specific actuator, send an inquiry to the email address in the contact tab.

Enerpac single-acting hydraulic cylinders 

Single-acting hydraulic cylinders are among the most commonly used components in power hydraulics systems. They are distinguished by a simple yet exceptionally effective design that allows for high force with relatively small device dimensions. Hydron offers professional Enerpac cylinders that combine durability, high operating pressure, and safety of use — everything you need in workshop, service, or industrial work. What characterizes a single-acting cylinder? A single-acting hydraulic cylinder (also called a single-acting actuator) is a device that performs a working movement in one direction – through the action of hydraulic pressure on the plunger. Plunger return occurs automatically — most often via a return spring, gravity, or external pressure after unloading. Thanks to this design, single-acting actuators are simpler, more compact, and less demanding to maintain than their double-acting counterparts. This is an ideal solution for applications where movement in one direction is sufficient — e.g., lifting, pressing, or straightening elements.

Example applications of single-acting cylinders

Enerpac single-acting actuators are used in many branches of industry and technical workshops where reliability and precision count. They are used, among others, in: lifting heavy loads, machinery, and steel structures, assembly and service work, e.g., in production and repair plants, pressing and positioning elements in technological processes, pushing out bushings, pins, or bearings in machine services, repairs of steel structures, straightening frames and vehicle elements, force and measurement tests where precise movement in one direction is required. Thanks to their simplicity of operation and high working pressure (up to 700 bar), Enerpac cylinders are commonly used in sets with manual, pneumatic, or electric pumps, creating mobile hydraulic systems.

Construction and properties of Enerpac actuators

Enerpac single-acting cylinders were designed for long-term and trouble-free operation. Their bodies are made of high-quality durable steel, and plunger surfaces are protected against corrosion and wear. Internal seals with high resistance to pressure and temperature guarantee tightness even under intensive use. Most Enerpac models are equipped with: safety valves, protecting the system against excessive pressure increase, a return spring, enabling fast and automatic plunger return, CR-400 quick-couplers, which facilitate connection to Enerpac pumps, a plunger with a chrome surface, ensuring smooth and precise movement. Thanks to this, Enerpac actuators stand out for their reliability, safety, and exceptional service life.

Popular Enerpac single-acting cylinder series

In the Hydron offer, you will find various series of single-acting cylinders, tailored to user needs: RC Series – classic single-acting actuators, universal in application, available in many sizes and strokes, RCH Series – cylinders with a hollow plunger, allowing elements such as bolts or rods to pass through the center of the plunger, RAR Series and RAC – lightweight, low-profile designs that work perfectly in tight spaces or during machine assembly. Each of these models is factory tested and complies with strict Enerpac safety standards.

Short hydraulic actuator

A short hydraulic actuator is a special type of hydraulic actuator with a small total length and a short plunger stroke. It was designed to work where assembly space is highly limited, yet high working force is required. These types of actuators use hydraulic oil pressure to generate significant pressure with minimal plunger extension. Thanks to their compact, tight design, they are often referred to as low-profile or compact actuators. A short hydraulic actuator is used, among others, in presses, assembly tools, for straightening, lifting elements, spreading steel structures, as well as in mobile services and the maintenance industry. It is perfectly suited for situations where a classic long-stroke actuator cannot be applied due to lack of space. In practice, such actuators offer high durability, tightness, and the ability to work under high pressure, making them a reliable solution in demanding industrial conditions. Hydron's offer includes various variants of short hydraulic actuators, tailored to specific applications and operating parameters. If you need assistance in selecting the right actuator for your application, Hydron specialists provide technical support at every stage of selection and purchase.

Small hydraulic actuators mini hydraulic actuators

Small hydraulic actuators, often referred to as mini hydraulic actuators, are compact devices that perform linear movement using hydraulic oil pressure. Thanks to their small dimensions and precise design, they are an ideal solution for applications where space is limited, yet high operating force is needed. Mini hydraulic actuators have been used for years in modern industry, service workshops, and mobile maintenance units, where compactness combined with high power is a key advantage. Small hydraulic actuators find wide application in tasks requiring precise displacement and high forces with minimal stroke. For example, they are perfect for lifting and moving heavy components in tight spaces, in workshop presses for pressing and straightening, and as tools supporting the assembly and disassembly of machine components. Their advantage is also the ability to work under high load conditions and variable temperatures, making them reliable even in harsh industrial environments.

Selection of hydraulic actuators

The selection of hydraulic actuators is one of the most important stages in the design and modernization of power hydraulic systems. A correctly selected hydraulic actuator determines work safety, the durability of the entire system, and the actual force that can be obtained in a given application. In practice, this means not only choosing the right model but also matching its parameters to the machine's operating conditions, load, and mounting method. Hydron's offer includes professional Enerpac hydraulic actuators, which have been used for years in industry, technical services, energy, and the construction sector. The Enerpac brand is known for its reliability, high operating parameters, and precise workmanship, which significantly facilitates the correct selection of hydraulic actuators even for very demanding applications.
