Installation of the hydraulic U-ring for shafts

The hydraulic U-ring seal for shafts is not a completely oil-sealed condition, as the reciprocating movement of the piston rod always brings out oil. However, this leakage must be as small as possible. On the contrary, if the piston rod reciprocating movement, without bringing out the slightest oil, so that the piston rod in dry friction, but will affect the performance and life of the hydraulic cylinder, shaft with hydraulic U-ring seal is the core of hydraulic equipment!

Installation of hydraulic U-seals for shafts.

1.all to be used on the sealing tool components components and U-shaped seal clean, no dirt.

2.Assemble the seal securely into the piston groove.

3. then put the mandrel on top of the piston rod.

4. Place the seal on the mounting mandrel.

5. gently push the seal into the piston groove with the help of the mandrel, moving steadily and slowly.

6.subsequently remove the mandrel from the piston.

7. Push the sealing tool inwards while aiding the installation, so that the sealing tool completely covers the outside of the U-shaped seal and then remove the tool.
