We have developed ultra-precision tapered roller bearings for the machine tool industry, achieving rotational accuracy of up to 1 micron (μm). To meet the demands of high precision and high-speed operation, these bearings are manufactured using premium materials and advanced production processes, ensuring exceptional durability and reliability.
One of the key technologies is the high-precision tapered rollerswith accuracy up to Grade 1 and with roundness values below 0.5μm.
Compared with other roller bearings,tapered roller bearing has its unique design.The end diameter of roller is different that is why it is called “tapered roller”.Jiayu Tapered roller bearings consist of four basic components –the inner ring(cone),the outer ring(cup),taper roller and cage.
