This standard specifies the characteristics of rigid single row ball bearings in corrosion resisting steel with a solid or lightweight flanged alignment housing, designed to withstand only slow rotations and slight oscillations under load.
They are intended for use in the hubs of torsion lever and in separated supports for airframe/aerospace applications.
The airframe rolling bearings defined in this standard may be used in the temperature range from – 54 °C to 150 °C.
However, being lubri
