Hydraulic cylinders normally have an oil seal, intake, outlet and a piston rod. When hydraulic fluid is released into the expansion chamber, the seals ensure that the fluid does not escape to the sides of the piston. To accommodate the intense pressure, the piston will be pushed forward or backwards. If the seal is damaged, the fluid will escape to the sides and lead to power losses. Hydraulic cylinder seal replacement will, therefore, be needed to ensure there is no more power loss.
The replacement should be done by a professional to ensure it is done properly. Ideally, you should hire someone who has been in the industry for several years and maintained a great reputation. Therefore, you should consider reading reviews as well as testimonials before making a decision. This will help to ensure you make the right decision.
