ÖNORM EN 2011

This standard specifies the characteristics, of rigid single row ball bearings of 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. The airframe roller bearings defined in the present standard shall be used from - 54 to + 150 °C. However, being lubricated with the following greases: - very high pressure grease, ester type (code A) operational range - 73 to + 121 °C or - very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range - 54 to + 177 °C (refer to EN 2063), their field of application when lubricated with code A grease shall be limited to + 121 °C.
