They are intended for use between fixed and moving parts of the aircraft structure and their control mechanisms. The airframe rolling bearings define
22、d in this standard are used from - 54 OC to + 150 OC. However, being lubricated with the following greases : - very high pressure grease, ester type (code A), operational range - 73 OC to + 121 OC or - very high pressure grease, synthetic hydrocarbons, general purpose (code BI, operational range - 5
