65Mn Spring Steel Material: Quenched and tempered, possessing high elasticity and wear resistance, suitable for vibration and impact conditions in engineering machinery, preventing deformation or breakage of the retaining ring.

Open Elastic Design: Allows radial contraction during installation, automatically springing back after embedding into the shaft groove, ensuring a tight fit and precise positioning, requiring no additional fasteners, and facilitating easy assembly and disassembly.

Zinc-plated passivated surface treatment: Improves corrosion resistance, suitable for harsh conditions such as humid and dusty environments, extending service life.

Original Manufacturer Compatibility Guarantee: Manufactured by Caterpillar, dimensions perfectly match the shaft groove, avoiding positioning failure or component wear caused by tolerance deviations, ensuring equipment operational stability.

Installation and Maintenance Points (Original Data)

Installation Procedure: Clean the shaft groove and retaining ring. Use retaining ring pliers to open the retaining ring, embed it into the shaft groove, ensuring the retaining ring is fully engaged at the bottom of the groove. After installation, check for axial movement, no deformation of the retaining ring, and no scratches on the compatible journal.

Maintenance Cycle: Check the retaining ring’s elasticity and surface condition every 2000 hours. Replace it immediately if deformation, cracks, or corrosion are found.

Common Troubleshooting: If the retaining ring’s elasticity fails, causing component movement, replace the retaining ring. If the shaft groove is worn, resulting in excessive clearance, repair the shaft groove or replace the shaft journal. If the retaining ring is broken, check if it is installed correctly to avoid uneven loading.
