•High carbon bearing steel : after heat treatment, it has hardness and toughness, better grinding quality. good flexibility, and longer using life span.
•HRC46
•Surface roughness: within RZ2.5
•Chucking range: ER=0.5mm, ER11/16/20/25/32/40=1mm. But if the internal hole is less than 2.5mm, the chucking range will be 0.5mm.
•The cincentricity is totally examined according to DIN norm. There are three kinds of classes for precision: general class 0.02mm. A class 0.01mm, and up class 0.005mm.
•UP class is recommended to be used with HSP clamping nut. It will have better stability.
