As EP series bearing greases are included in the bulk material, none On how long the working time of the bearing grease will continue to play from the friction surface seepage Long-term lubrication, while the traditional powder metallurgy oil-bearing in the use of the process benefits The lubricating oil in the micropores acts as a self-lubricating effect when these lubricants are depleted or After the end of volatile bearing wear will rapidly intensify, at this time to declare the effective bearing With the end of life.
1: - 40 ℃ ~ + 80 ℃;
2: general purpose strong suitable for most of the use of low and medium load occasions;
3: suitable for dry operation, maintenance-free, corrosion resistance;
4: damage to the shaft is minimized;
5: very low sliding friction coefficient.

Plastic bearing has longe service vs Metal bearing lubricating oil is life easy to be failed
Engineers are dedicated on the performance improvement on the self- lubricating materials derives the result that EP Series Materials are with excellent self- lubricating features and wear resistance Features. High- strength fibers used in the engineering plastics fantastically improve the material load (Graphl). Special grease immersion in the plastic can decrease the friction coefficient of the material therefore to proiong the bearing sevice life. High-performance engineering plastics body material mainly service as wear- resistant vector. The reinfoced fiber improves the load and impact resistant capacity of the beaing. Special grease decreases the fiction coefficient for a better selflubricating performance.
