Hydraulic cylinder is the hydraulic energy into mechanical energy is widely used in a variety of mechanical systems, oil seal is a part of it. Large hydraulic cylinder, it relies on oil to operate, after a long time, the oil will deteriorate, then we have to replace the oil seal, it replaces the oil seal methods are:

1. First remove the brake spring at both ends of the hydraulic cylinder or the brake screw.

2, Panasonic hydraulic cylinder on both sides of the guide sleeve or a guide sleeve.

3. Then take out the seal ring of the hydraulic cylinder guide sleeve and replace it with a new seal, and the piston rod oil seal inside the hydraulic cylinder is replaced at the same time.

4. If the hydraulic cylinder seal ring is deformed or aging, it is difficult to remove it. You can remove it by soaking the seal ring with boiling water for 10 minutes.

The oil seal of the hydraulic cylinder is the customary name of the general seal, which is simply the sealing of the lubricating oil. It is used to seal grease mechanical components, and it isolates the parts that need lubrication in the transmission parts from the output parts, so that the lubricating oil will not leak.
