22、e characteristics of rigid single row ball bearings in corrosion resisting steel of diameter series0 and2 1)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, in parti

23、cular the mounting of more than one bearing on the same shaft axis, which may require reduced clearances and runouts (axial and radial). The airframe rolling bearings defined in this standard are used from54 C to+150 C. However, being lubricated with the following greases: very high pressure grease,

24、 ester type (codeA), operational range73 C to+121 C or very high pressure grease, synthetic hydrocarbons, general purpose (codeB), operational range54 C to+177 C (seeEN3280), their field of application when lubricated with codeA grease is limited to+121 C. 2 Normative references This EuropeanStandar
