Installation and Maintenance Points:
**Before installation, clean the shaft groove and retaining ring, ensuring they are free of oil, rust, and impurities. Inspect the retaining ring for deformation, cracks, or loss of elasticity.

Use dedicated snap ring pliers (external snap ring pliers) to pry open the retaining ring and insert it into the corresponding groove on the shaft, ensuring the retaining ring is fully embedded without any protrusion or tilting.

After installation, check the fit between the retaining ring and the shaft groove. Gently move it by hand; there should be no looseness. Ensure reliable axial positioning of the bearing and other components, with no room for movement.

Maintenance: Inspect every 1000 working hours. If the retaining ring shows deformation, rust, or decreased elasticity, replace it immediately to prevent axial movement of components and subsequent malfunctions. Use specialized tools during replacement; never pry forcefully, as this may damage the retaining ring or shaft groove.
