> φ5-φ140.8±0.2
> φ14.1-φ251±0.3
> >φ25.1一φ481.2±0.4
>>φ48.11.6±0.5


Center and Exit hole tolerance

>φ0.8一φ1.5±0.1
>φ1.6一φ3.0±0.2
>φ3.1一φ8.0土 0.3


Length & Concentricity

Basic allowance(mm)Sintering Tol. (mm)Concentricity
+(0.4+0.5%L)±0.5%L<=0.3
For example, if L=100mm, then it's basic allowance is +0.4+0.5%*100=0.9mm Sintering tolerance is ±0.5%*100= 100.9±0.5mm.
