Research and Development
Apparently, the concentration of stress per relieved end curve improves effectively because of round transition between arc slope and straight generatrix. So the lifespan of this roller & needle roller will extend a lot. In recent years, the company has developed roller & needle roller with logarithm curve generatrix (variant crowned type), whose precision index of each technology equals to international advanced level. The experts indicate that the lifespan of variant crowned roller & needle roller can be increased by several times because of evener stress distribution, normally 2 to 3 times longer.The surface process of high-precision cylindrical roller & needle roller adopts crowned super-precision technology. The roughness of surface will decrease and round deviation will be improved and cross net remained will make surface reserve oil film for coating after super-precision treatment so as to reduce noise and vibration of bearing for longer lifespan and to improve performance.
Bearing assembly factory could select production according to requirement of designer, or consult with our professional engineers and technologists of technique department, then choose suitable rollers & needle rollers as well.
