Structural and Performance Characteristics:

Elastic Positioning: Made of 65Mn spring steel with excellent elasticity, the open design allows for quick installation into the shaft end groove, providing stable axial positioning force and preventing component movement during equipment operation (Cat®…).

Wear and Corrosion Resistance: Surface oxidation and blackening treatment enhances wear and corrosion resistance, suitable for harsh working conditions in construction machinery, and resistant to rust and deformation over long-term use (Cat®…).

Lightweight: Lightweight, does not add extra burden to the equipment, requires little installation space, and fits compact shaft end areas.

Installation and Maintenance Points (Original Data)

Installation: Clean the shaft end and groove to remove oil and rust. Ensure the groove dimensions match the diameter and width of the retaining ring wire cross-section.

Use dedicated retaining ring pliers to pry open the retaining ring opening, align it with the groove, and slowly release it, ensuring the retaining ring is fully engaged without looseness or misalignment.

After installation, check the fit between the retaining ring and the shaft end to ensure there is no axial clearance and prevent it from falling off during operation.

Maintenance: Check the condition of the retaining ring every 500 hours. If cracks, deformation, or loss of elasticity are found, replace it immediately.

Avoid striking the retaining ring with hard objects to prevent material damage that could affect its elasticity and positioning performance.
