INA bearing seal performance are important factors in ensuring effective sealing material, choice of sealing materials, and main seal element is based on the work environment, such as temperature, pressure, the use of the media and sports. Basic requirements for sealing material are as follows:
1.IKO bearing wear, no corrosion of metals;
2. oxygen-resistance and good aging resistance, durability;
3.NSK bearing high-temperature and low-temperature-resistant, does not decompose at high temperatures, soft, does not harden at low temperatures;
4.SKF bearing compatible with the media, does not produce swelling, decomposition, and hardening;
5. appropriate flexibility and hardness, small compression set;
6.FAG bearing a certain mechanical properties, such as tensile strength, elongation rate;
7. easy processing and low prices;
