Sealing materials play a crucial role in the performance and longevity of INA bearings. The primary function of these materials is to maintain effective sealing, preventing contamination, lubricant leakage, and damage from external elements. The selection of the appropriate sealing material depends largely on the operating conditions of the bearing, including temperature, pressure, the type of working medium, and the nature of motion. Here are the key functional requirements for sealing materials used in INA bearings: 1. **Wear Resistance**: The material should be highly resistant to wear and not cause corrosion to metal components. 2. **Oxidation and Aging Resistance**: It should remain stable over time, resisting degradation due to oxygen exposure and environmental aging. 3. **Temperature Stability**: The material must perform well under both high and low temperatures without softening or hardening. 4. **Chemical Compatibility**: It should be compatible with the working medium (such as oil or grease), avoiding swelling, cracking, or hardening. 5. **Elasticity and Hardness**: The material needs to have the right balance of elasticity and hardness to maintain a tight seal without permanent deformation. 6. **Mechanical Strength**: It should possess sufficient tensile strength and elongation properties to withstand mechanical stress. 7. **Processability and Cost-Effectiveness**: The material should be easy to shape and process, while also being economically viable. By meeting these criteria, sealing materials can significantly enhance the reliability and service life of INA bearings in various industrial applications.
