4 Benefits
Widely used in various fields of industry Metal the cylindrical seal ring installed in the bore particularly strong and precise, the cylindrical sealing low viscosity and gases. Installation quit sealant is recommended in the outer coating. Cavity and machining standard (see: Sealing Mechanism and Surface speed of shaft) Axis: Tolerance: ISO h 11 Concentricity: IT 8 Roughness R a = 0,2 - 0,8 m R z = 1,0 - 5,0 μm R max = <6,3 μm Hardness: 45-60 HRC Finish: None to the state, it is best to use horizontal feed grinding Cavity: Tolerance: ISO H8 Roughness: R z = 6,3 - 16 μm
6 Install Required by DIN3760, careful installation is a prerequisite to ensure good seals
