1 Scope This standard specifies the characteristics of spherical plain bearings in corrosion resisting steel, with self-lubricating liner, wide 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. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

Δ dmp = single plane mean bore diameter deviation Δ ds = deviation of a single bore diameter Δ Dmp = single plane mean outside diameter deviation Δ Ds = deviation of a single outside diameter α = angle of tilt of the outer ring with respect to the inner ring, the spherical surface of the outer ring being completely in contact with the inner ring 4 Required characteristics 4.1 Configuration, dimensions, tolerances and mass According to Figure 1, Figure 2 and Table 1. The dimensions are expressed in millimetres and apply after surface treatment. 4.2 Surface roughness According to Figure 1 and Figure 2. The values are expressed in micrometres and apply before surface treatment. 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 requirements 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. 7 Technical specification According to EN 2755 8 Quality management system The manufacturer’s operations shall be an approved production organisation for aerospace products and shall demonstrate that it has implemented and is able to maintain a quality management system (e.g. according to EN 9100 or another in aerospace accepted and established quality management system).BS EN 2585 pdf download.
