Dalian Dayou advanced ceramic co., Ltd has been pursued the study and produce of ceramic balls for ten years. And the technology is being top level at home. The list fellow is the advantage of the precision ceramic balls.
　1、Super precision
　　Ceramic balls that grade of G3 and the value of quiver is less than 26 decibels can be produced according to particular technology which studied out by DAYOU.
　2、Specialization
　　The ceramic balls using in “DAYOU” precision bearings are all produced by ourselves, so we know much more about the ceramic balls which using in the bearings. DAYOU specialize in the manufacture of ceramic balls.
　3、Many types of material and widely range of size
At present, Si3N4 ceramic balls, ZrO2 ceramic balls, Al2O3 ceramic balls can be produced which the diameter from 0.5mm to 80mm. Except that, some other ceramic balls can be produced in order.
　4、Particular manufacture technology for big balls
While the balls bigger than 1〞(25.4mm), DAYOU can ensure 100% odds and a high precision also. For example the ball 1〞(25.4mm) may achieve the grade of G5, and the ball 2〞(50.8mm) may achieve the grade of G10.

        Based the manufacture of precision ceramic balls, the company invented the technology for polish of cemented carbide balls, which the balls have some characteristics below.
　1、High precision
　　DAYOU supply a batch production cemented carbide balls, which can ensure the grade of G10. When the balls bigger than 1〞(25.4mm), DAYOU can ensure 100% odds and a high precision also.
　2、Widely range of size
　　cemented carbide balls which the diameter from 0.5mm to 80mm can be produced.
　3、Many types of material
　　YG6、YN12、TiC ceramic balls and so on that the diameter from 0.5mm to 80mm can be produced in order.
