Signs That an Industrial Hydraulic Cylinder Needs Repair

Posted on: 27 October 2023

Industrial hydraulic cylinders are crucial components in a wide range of heavy-duty applications. They are used in heavy machinery, manufacturing equipment, and construction vehicles, among others. These cylinders are responsible for converting fluid power into linear motion and play a crucial role in keeping industrial operations running smoothly. However, like any other mechanical component, hydraulic cylinders can eventually break down and require repair. This blog post will explore some signs that an industrial hydraulic cylinder needs repair.


A hydraulic cylinder relies on the hydraulic fluid to operate, and any leaks can significantly affect its efficiency. While hydraulic fluid leaks may be caused by several factors, including a damaged cylinder seal, it is a warning sign that the cylinder needs repair. Leaks may manifest as drips or as visible puddles of hydraulic fluid. If not addressed promptly, leaks can cause severe damage to the cylinder, leading to costlier repairs.

Reduced Performance

The performance of a hydraulic cylinder can be reduced by a range of factors, including foreign matter in the hydraulic fluid or damaged or worn internal components. Signs of reduced performance include slow operation, decreased power, and unexplained jerks. If you notice any of these, it is a good idea to have your cylinder checked by a qualified technician.

Unusual Noises

Unusual sounds from a hydraulic cylinder, such as hissing or clanking, are often an indication of internal damage. The sounds may be caused by worn or damaged components, cavitation, or air in the system. Any unusual sounds from the cylinder should prompt you to seek professional assistance.


Hydraulic cylinders generate heat during operation, and the system relies on a cooling circuit to maintain safe temperatures. However, if the cylinder starts to overheat, it is a sign of problems. Overheating can be caused by several factors, including a clogged or damaged filter, blocked cooling lines, or internal damage. Failure to address overheating can lead to system failure or damage to other components.

Visual Damage

Damage to the external surface of a hydraulic cylinder is a sign of internal problems. Cracks, dents, or visible leaks may indicate a damaged or worn-out seal, foreign matter in the system, or other internal issues. Visual damage should not be ignored, and professional repairs should be considered to prevent further damage.

Industrial hydraulic cylinders are critical components in heavy-duty applications, and proper maintenance is essential to keep them running efficiently. Signs of problems, including leaks, reduced performance, unusual noises, overheating, and visual damage, should be taken seriously and addressed promptly by a qualified technician. By keeping a close eye on your hydraulic cylinders and addressing problems as soon as they arise, you can keep your equipment productive and extend its lifespan.
