Enerpac hydraulic cylinders help cranes and excavators to lift heavy objects by using a pressurised fluid. When fluid enters the cylinder, it exerts a force on the piston, which initiates its movement. Later, the rod transfers this motion for lifting or pushing actions.
In addition, these hydraulic cylinders are useful in manufacturing machinery to exert force for bending, cutting or shaping materials. Moreover, these cylinders find use in automotive systems in terms of braking, steering and suspending loads.
Hydraulic Cylinder Components
Hydraulic cylinders consist of several primary components. They include the base, plunger, stop ring, coupler(s) and saddle. Additional components and features such as collar threads, relief valves, lifting eyes & lock nuts vary based on the return type and category. The diagrams below illustrate a hydraulic cylinder’s primary and common components.
- Firstly, the grooved saddle is used to support and hold the hydraulic cylinder.
- The hydraulic plunger then moves back and forth to produce hydraulic force in a linear motion.
- The Enerpac cylinder base provides a mounting surface for the cylinder.
- Additionally, the coupler is designed to connect the cylinder to other parts for a smooth fluid flow.
- The purpose of the base holes is to facilitate easy attachment to a surface.
- Moreover, the collar thread helps in the fastening process.
- To protect from friction and potential damage, the wear band acts as a shield.
- Furthermore, the seal is crucial in preventing hydraulic fluid from leaking out.
- Also, the spring on these cylinders provides positive or negative force for the movement.
- Similarly, the stop ring prevents excessive extension or retraction.
- When needed, the lifting eye provides a convenient point for attaching a lifting device.
- Lastly, the lock-nut securely fastens and locks components in place, ensuring stability.

How to Bleed Double-Acting Hydraulic Cylinders?
If you have been facing pressure drops; noisy, jerky or sluggish responses; and spongy cylinder operations, then your hydraulic cylinders need purging. The prime cause of cavitation is trapped air in a hydraulic system. This video will help you understand the steps of bleeding down a hydraulic cylinder.
How to Plumb Single-Acting Hydraulic Cylinders?
- To begin with, position the power unit (manual hand pump, air-powered hydraulic pump or hydraulic-electric pump) near the cylinder.
- Then, identify the inlet and outlet ports for fluid entry and exit.
- Next, measure and cut hydraulic hoses to appropriate lengths.
- Then, install fittings on each end of the hydraulic hoses.
- Later, connect one end of the hydraulic hose to the inlet port and the other to the outlet port.
- Then, fill the hydraulic reservoir with Enerpac hydraulic oil.
- Finally, open the bleeder valves to allow any trapped air to escape from the system.
