What are the different types of hydraulic cylinders?

There are three main types of hydraulic cylinders. The single-acting cylinder is supplied with oil in only one direction, with return by spring or gravity. The double-acting cylinder receives pressure in both chambers, allowing movement control in both directions. The telescopic cylinder offers a long stroke in a compact space, ideal for buckets and lifting equipment.

What could cause a hydraulic cylinder to fail holding pressure?

A hydraulic cylinder that fails to hold pressure is most often caused by worn seals that allow oil to leak internally and prevent pressure retention. A scratched or corroded rod accelerates this degradation. Faulty check valves or a defective hydraulic distributor can also cause pressure drops. Finally, oil contamination by abrasive particles worsens internal surface wear.

What is the cost of repairing a hydraulic cylinder?

The repair cost for a hydraulic cylinder varies with its size, technical complexity, and extent of damage. While simple seal replacement is affordable, machining a rod or barrel increases the cost significantly. For agricultural or construction machinery, a complete overhaul of a worn part is often expensive. Choosing a reconditioned used cylinder is usually a more economical and faster alternative than a complex repair, while ensuring optimal performance.

Is a reconditioned used hydraulic cylinder reliable?

Yes, provided it has undergone rigorous reconditioning . At TMC Bejenne, each cylinder is fully disassembled, inspected, and bench-tested hydraulically before being resold. Seals and packings are systematically replaced, and sliding surfaces verified. A reconditioned cylinder under these conditions offers performance comparable to an original part, with reliability suited to agricultural and construction equipment requirements.

How to choose a hydraulic cylinder for agricultural equipment?

To choose the right agricultural hydraulic cylinder , first identify the operating pressure required by your hydraulic circuit, usually expressed in bars. Stroke and piston diameter must exactly match your equipment's original dimensions. Mounting type, pin sizes, and compatibility with your tractor or machine are also critical points to verify before purchase.
