3 Terms, definitions and symbols For the purposes of this document, the terms and definitions given in TR 4475 apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: — ISO Online browsing platform: available at http://www.iso.org/obp — IEC Electropedia: available at http://www.electropedia.org/ Symbols of limit deviations are in accordance with definitions of ISO 1132-1. α maximum angle of tilt of the outer ring with respect to the inner ring, with the spherical surface of the outer ring being completely in contact with the inner ring C a permissible static axial load C s permissible static radial load ∆ dmp single plane mean bore diameter deviation ∆ Dmp single plane mean outside diameter deviation ∆ ds deviation of a single bore diameter ∆ Ds deviation of a single outside diameter
4 Requirements 4.1 Configuration, dimensions, tolerances and mass Configuration, dimensions, tolerances and mass shall be according to Figure 1 to Figure 5 and Table 1. Table 1 and Table 3: Dimensions and tolerances are expressed in millimeters (inches). Figure 1 and Figure 2: Dimensions and tolerances for Ra max. are expressed in μm (μin). Values apply after to surface treatment. 4.2 Surface roughness Surface roughness shall be according to Figure 1 and Figure 2. Values in micrometer (micro inches), apply prior to surface treatment. Surface roughness is measured before surface treatment.
4.3 Material Inner ring: see EN 2030; hardness 55 ≤ HRC ≤ 62. Outer ring: see EN 3161; hardness 28 ≤ HRC ≤ 38; before swaging.
4.4 Surface treatment Surface treatment shall be as defined in chapter 5 (designation) with following codes: — code T: Surface treatment according to ISO 8075 for inner ring before swaging; outer ring: no treatment; — code P: Surface treatment according to ISO 8075 for inner ring before swaging; cadmium plating of outer ring according to EN 2133, 5 μm to 8 μm (200 μin to 300 μin).
4.5 Swaging groove Swaging groove shall be described in chapter 5 (designation) with following codes: Without swaging groove code S: Surface treatment according to ISO 8075 for inner ring before swaging. Cadmium plating of outer ring: 5 μm to 8 μm (200 μin to 300 μin) according to EN 2133 (cylindrical surface area and chamfers and both end surfaces at manufacture’s option), followed by chromating. With swaging groove code R: Surface treatment according to ISO 8075 for inner ring before swaging. Cadmium plating of outer ring: 5 μm to 8 μm (200 μin to 300 μin) according to EN 2133 (cylindrical surface area, broken angles and radii, respectively, as well as both end surfaces up to the swaging grooves), followed by chromating.BS EN 6097 pdf download.
