What are hydraulic cylinders?
A hydraulic cylinder consists of a cylinder barrel containing a piston and a piston rod that move back and forth. The barrel is sealed with a cylinder cap at the bottom. The piston rod protrudes from the housing at the other end, which is sealed with a cylinder head.
Hydraulic cylinders exert a linear force on a product or machine by means of hydraulic fluid (oil). The fluid enters the barrel at one end by means of a hydraulic pump causing the piston rod to extend. The liquid is then discharged on the other side. If the pressure shifts to the rod end of the piston, this will result in a pulling movement.
The types of custom hydraulic cylinders that we produce
We base ourselves on our standard cylinders to produce custom hydraulic cylinders, which we adapt for your application:
1. Single-acting hydraulic cylinders
Single-acting cylinders only push. This hydraulic cylinder does not have a fluid port at the rod end.
2. Double-acting hydraulic cylinders
A double-acting cylinder pushes and pulls thanks to the fluid port at the rod end. This makes retraction or extension possible.
3. Telescopic cylinders
In the case of hydraulic cylinders, the mounts, the thickness of the base, the cap and the piston are a certain length, so that the installation length is greater than the stroke length. That is why telescopic cylinders are used for shorter installation lengths. The piston rod serves as the housing for these cylinders. It contains (anything between 2 and 10) sections, each of which is a different diameter that extends one by one.
