DIN EN 4033:2008 Aerospace series - Bearings, airframe rolling - Rigid single row ball bearings in corrosion resisting steel - Diameter series 8 and 9, reduced internal radial clearance - Dimensions and loads; German and English version EN 4033:2007
This standard specifies the characteristics of rigid single row ball bearings, in corrosion resisting steel, reduced internal radial clearance, diameter series 8 and 9 , designed to withstand only slow rotations and
oscillations under load.
They are intended for use between fixed and moving parts of the aircraft structure and their control
mechanisms
They are intended to be used in the temperature range: - 54 ℃ to 150 ℃.
However, being lubricated with the following greases:
very high pressure grease, ester type (code A), operational range - 73 ℃ to 121 ℃ or
very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range - 54 ℃
to 177 ℃ (see EN 3280),
their field of application when lubricated with code A grease is limited to 121 ℃.
