BS EN 6097-2019 pdf free download.Aerospace series – Bearing, spherical plain, metal to metal, extra wide inner ring in corrosion resisting steel – Dimensions and loads – Inch series.
This European standard specifies the characteristics of inch based spherical plain bearings, metal to metal, in corrosion resisting steel, extra wide inner ring inch series.
They are intended for use in fixed or moving parts of the aircraft structure and their control mechanisms.
The slide hole treatment either at the outer ring or inner ring.
