This standard specifies the basic dimensions and tolerances of rotating shaft lip seals (hereinafter referred to as seal rings) with shaft diameters ranging from 6 to 400 mm and corresponding inner hole diameters of sealing chambers (hereinafter referred to as chambers) ranging from 16 to 440 mm. In order to ensure the interchangeability of sealing rings produced by different manufacturers, this standard also specifies the dimensions and tolerances of shafts and mounting holes. This standard is applicable to sealing rings whose working pressure is equal to or less than 0.05MPa, and not applicable to higher working pressures. In order to make the sealing ring provided by the manufacturer meet the design and use requirements, Appendix A of this standard recommends the relevant report format of the sealing ring for signing the agreement between the supplier and the buyer.
