former need extensive grinding that is inher-ent to the design. But recent manufacturing advances and economies of scale let square rails now compete with round in a broad range of applications. The criteria for choosing one over the other are no different than choosing any other machine component: define system objectives, then consider factors such as load capacity, stiffness, accuracy,How ball bearings are manufactured | Engineering360,Ball bearings are rolling element bearings that use balls to separate the bearing races and provide smooth, low friction motion in rotary applications. Ball bearings are manufactured in hundreds of sizes, from the ultra-small 1.50 mm diameter bearing for use with miniaturized medical devices and micro-motors, to bearings over 15 feet in diameter for use in heavy equipment.precision bearing,special bearing ZYS,718, 719,70, 72 series single row angular contact ball bearing A new generation of precision angular contact ball bearings have been developed by ZYS for the machine tool spindle. Comparing with general precision bearings, angular contact bearings are greatly improved in terms of rotation accuracy, limit speed, carrying capacity and reliability; and the size range is also wider.
