They are intended for use between fixed and moving parts of the aircraft structure and their control mechanisms.
20、2 Fields of application The airframe roller bearings defined in the present standard shall be used from54to+150 C. However, being lubricated with the following greases: very high pressure grease, ester type (codeA), operational range73to+121 C or very high pressure grease, synthetic hydrocarbons, ge
21、neral purpose (codeB), operational range 54to+177 C (refer toEN2063), their field of application when lubricated with codeA grease shall be limited to+121 C. 3 References ISO 15:1981, Rolling bearings Radial bearings Boundary dimensions General plan.
