A seal ring for a spring link is a sealing component used in suspension systems to protect connection points. Its function is to prevent dirt, moisture, and contaminants from entering the joint, helping to maintain proper lubrication and performance.
Key specifications include inner and outer diameter, thickness, material (such as rubber or elastomer), durability, and compatibility with the suspension system. It must withstand mechanical stress and environmental exposure.
Replacement is necessary when the seal is worn, cracked, or damaged. Common symptoms include contamination of the joint, reduced suspension performance, or visible deterioration.
