Abstract
This document specifies the characteristics of spherical plain bearings, metal to metal, in corrosion resisting steel, cadmium plated and chromated, wide series, inch series for aerospace applications. Spherical plain bearings, metal to metal, in corrosion resisting steel, cadmium plated and chromated, wide series, are intended for use in fixed or moving parts of the aircraft structure and their control mechanisms. Spherical plain bearings, metal to metal, in corrosion resisting steel, cadmium plated and chromated, wide series, are intended for use in the temperature range −54 °C to 150 °C, and intended to be lubricated by means of the following greases: - Code A: grease conforming to MIL-PRF-23827, operating temperature range −73 °C to 121 °C; - Code B: grease conforming to MIL-PRF-81322, operating temperature range −54 °C to 177 °C. For the purposes of this document, the range of application for bearings lubricated with grease conforming to code A is limited to 121 °C. For the purposes of this document, the range of applications for bearings lubricated with grease conforming to code B is limited to 177 °C. NOTE In both cases it is important to provide the spherical surface of the outer or inner ring with a dry-film lubricant conforming to MIL-PRF-46010 or equivalent (anti-seizing protection).
