| ①,In the standard text, φ119 corresponds to the dc minimum value of 188.15, but the corresponding deviation here should be 1.85 mm, that is, the actual minimum value is 200-1.85=198.15 mm. (In DIN 522, when h is less than 4 and the product grade is Class A, the dimensional tolerance of d2 is h15, and the corresponding deviation is 1.85 mm when dc is 200 mm). ②,Material： 1）steel , hardness class 140HV, hardness HV140-250；hardness class 200HV, hardness HV200-250； 2）stainless steel , hardness class 140HV, hardness HV140-250；hardness class 200HV, hardness HV200-250；material (steel group) A2 and A4, F1, C1 and C4 3）Washers may be made of non-ferrous metals or other materials, SUbject to agreemen 4）For h not exceeding 0,5 mm, the hardness shall be HV 2 and for h exceeding 0,5 mm, HV 10. |
