The primary function of sealing materials used in INA bearings is to ensure effective and long-lasting sealing performance. The selection of the right material depends heavily on the operating conditions of the system, such as temperature, pressure, type of working medium, and the type of motion involved. Here are the key functional requirements that these materials should meet:
1. **Wear Resistance**: The material should be highly resistant to wear and should not corrode metal components over time.
2. **Oxidation and Aging Resistance**: It must resist oxidation and aging, ensuring long-term durability and stability under various environmental conditions.
3. **Temperature Stability**: The material should perform well under both high and low temperatures, maintaining its properties without softening at high temperatures or becoming brittle at low temperatures.
4. **Chemical Compatibility**: The material should remain stable when exposed to the working medium, avoiding swelling, degradation, or hardening.
5. **Elasticity and Hardness**: It should have appropriate elasticity and hardness to maintain a tight seal without permanent deformation.
6. **Mechanical Strength**: The material should possess sufficient mechanical properties, such as tensile strength and elongation, to withstand operational stresses.
7. **Processability and Cost-Effectiveness**: It should be easy to shape and process, while also being cost-effective for mass production.
In addition to these technical requirements, the material should also be compatible with the overall design of the bearing system and should support efficient assembly and maintenance processes. Proper material selection ensures not only the reliability of the seal but also contributes to the overall performance and lifespan of the bearing.
