1 Scope
This European standard specifies the characteristics of spherical plain bearing in corrosion rsisLsng steel, with self-lubricating liner, narrow series, for elevated load, at ambient temperature, with or without swaging groove, intended for use in the fixed or moving parts of the aircraft structure and control mechanisms.
They shall be used in the temperature range —55 °C to +163 °C.

4 Required characteristics 4.1 Configuration, dimensions, tolerances and mass According to Figures 1 and 2 and Table 1. The dimensions are expressed in millimetres and apply after surface treatment. 4.2 Surface roughness According to Figures 1 and 2. The values are expressed in micrometres and apply before surface treat- ment.4.4 Materials Inner ring: Steel according to EN 2030, hardness 55 HRC to 62 HRC Outer ring: Steel according to EN 3161, hardness 28 HRC to 37 HRC before swaging Liner: Self-lubricating low friction wear resistant material consistent with the require- ments of EN 2755 6 Marking According to EN 2424, style A. The marking position is at the manufacturer’s option. Bearings ordered without technology code shall be delivered marked with the code of technology used.BS EN 2584 pdf download.
