EN 3059:20074 1 Scope This standard specifies the characteristics of rigid single row ball bearings in steel, with cadmium-plated flanged alignment housing designed to withstand only slow rotations a

17、nd oscillations under load. They are intended for use in the hubs of torsion lever and in separated supports for airframe/aerospace applications. The airframe rolling bearings defined in this standard may be used in the temperature range from 54 C to 150 C. However, being lubricated with the followi

18、ng greases (see EN 3727): ester type very high pressure grease (code letter A), operating range from 73 C to 121 C or, synthetic hydrocarbons type very high pressure grease general purpose (code letter B) operating range from 54 C to 177 C. Their field of application when lubricated with code letter
