Attention should be paid to the installation and use of sealing ring:
Can not install the wrong direction and damage the lips. If there are scars above 50μm on the lips, it may cause obvious oil leakage.
Prevent forced installation. Do not use a hammer to knock in, but use a special tool to first press the sealing ring into the seat hole, and then use a simple cylinder to protect the lip through the spline. Before installation, apply some lubricating oil to the lips to facilitate installation and prevent burns during initial operation. Pay attention to cleaning.
Prevent overdue use. The service life of rubber seals for dynamic seals is generally 3000~5000h, and new seals should be replaced in time.
The size of the replacement seal should be the same. It is necessary to strictly follow the requirements of the instructions, and select the same size of the sealing ring, otherwise the tightness and other requirements cannot be guaranteed.
Avoid using old seals. When using a new sealing ring, carefully check its surface quality to ensure that there are no defects such as small holes, protrusions, cracks and grooves, and have sufficient elasticity before using it.
