EP plastic bearings and traditional oil bearing
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.
EP series of materials has excellent self-lubricating and wear resistance is mainly engineers take full advantage of the self-lubricating material modification technology, high-performance engineering plastics used in high-strength fiber to improve the material load and special grease reduced The friction coefficient of the material (Figure 1), thereby enhancing the comprehensive wear resistance of the material to extend the service life of the bearing. High-performance engineering plastics as the base material mainly as wear-resistant carrier; Reinforced fiber to improve the bearing in the bearing and impact resistance; Special grease reduces the coefficient of friction of the bearing from the role of lubrication.
Solid-lubricating and Maintenancefree Sliding Bearings
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.
