Repairing a hydraulic cylinder is extremely cost-effective compared to replacing a used or damaged cylinder with a new one. This cost-effectiveness is mainly evident in large-dimension cylinders and demanding cylinder designs. Such cylinders are often very expensive, and their overhaul typically costs less than 40% of the price of a new cylinder. Additionally, our restoration process ensures that the difference between the refurbished cylinder and a new one is practically imperceptible.
We specialize in restoring all types of hydraulic cylinders with a diameter of up to 1700 mm and a length of up to 18 meters.
The repair process involves three steps:
Diagnosing the Anomaly:
- We disassemble the cylinder, measure all mechanical components, and assess the extent of damage.
- Based on this evaluation, we determine which parts need replacement or repair.
- We accurately calculate the cost of repairing a damaged cylinder.
- If restoration is not economically viable, we recommend manufacturing a new cylinder.
- Upon request, we can provide all necessary technical documentation.
Carrying Out Repairs:
- Depending on the size and diagnostic findings, we:
- restore the cylinder body by grinding and honing the tube,
- replace or regenerate piston rods by grinding and chrome plating (or applying a ceramic coating),
- completely rebuild the piston, including the gasket seats,
- replace seals - if standard seals are unavailable, we manufacture new ones.
- repair cylinder head, and couplings, and change the bearings.
- Depending on the size and diagnostic findings, we:
Quality Control:
- Our testing and quality control procedures adhere to industry standards and regulations.
- Upon request, we can perform additional tests based on the client’s requirements.
Furthermore, we offer customers an inspection and condition assessment of existing hydraulic cylinders. Based on this assessment, we can provide cost-effective recommendations for cylinder renewal or replacement. Additionally, we provide customers with a maintenance plan that allows errors to be detected before an actual failure occurs.
Thanks to our in-house construction department and production capacity, we have the capability to repair and restore any hydraulic cylinder—even those for which spare parts are no longer available.
Some Frequently Asked Questions:
How long does it take to repair a hydraulic cylinder?
The renovation time depends on the complexity of the structures and the condition of the hydraulic cylinder. We understand the criticality of minimizing downtime for our customers’ production processes. Therefore, we collaborate closely to plan shutdowns efficiently. With our professionally trained and experienced team, along with our own production capacity and stock of input materials, we can perform repairs quickly and efficiently. Our key advantage lies in producing our own seals and sealing rings made of elastomers. We maintain various materials in stock for seal fabrication (PU, NBR, EPDM, Silicone, PTFE, etc.).
Can you replace older cylinders for which spare parts are no longer available?
Absolutely! Thanks to our construction department and production capacity, we can repair and restore any hydraulic cylinder. Our unique advantage is our in-house seal production, which allows us flexibility beyond standard seal offerings. Additionally, our designers often update outdated hydraulic cylinders with the latest design solutions according to industry standards.
- What is more cost-effective: rebuilding or replacing the hydraulic cylinder with a new one?
Refurbishing a hydraulic cylinder is extremely cost-effective compared to replacing a used or damaged cylinder with a new one. This cost-effectiveness is particularly evident in the case of large cylinders, as these cylinders can be quite expensive. Typically, the cost of restoring a cylinder does not exceed 40% of the price of a new cylinder. However, there are exceptions where replacing the cylinder with a new one may be more efficient. That’s why we offer our customers an inspection and assessment of the existing hydraulic cylinders. Based on this assessment, we provide recommendations regarding the feasibility of either renewing or replacing the cylinder. Our experts begin by disassembling the cylinder to assess the degree of damage. Then, we determine which parts need replacement or repair. All of this forms the basis for accurately determining the cost of repairing a damaged cylinder.
Can old and dirty hydraulic oil damage a hydraulic cylinder?
Dirty hydraulic oil is one of the primary causes of hydraulic cylinder damage. The presence of dirt in the oil leads to mechanical abrasion of seals and other softer components. This, in turn, results in oil leakage and the potential for hard particles to enter the system, causing damage to the cylinder. To prevent this, we recommend using a filter unit that effectively removes dirt from the oil and protects the hydraulic cylinder components.
