EN 3055:1994 Aerospace series - Bearings, airframe rolling - Single row self-aligning roller bearings in corrosion resisting steel; dimensions and loads
This standard specifies the characteristics of single row self-aligning roller bearings in corrosion resisting steel designed to withstand only slow rotations, oscillations and/or swivelling under load.They are intended for use in bell crank lever ends or atThe end of rigid flight control rods for transmissionpurposes, before or after servo operation.The airframe rolling bearings defined inThis standard are used from-54 ℃ to + 150 ℃.However, being lubricated withThe following greases :-very high pressure grease, ester type (code A), operational range-73 ℃ to + 121 ℃ or- very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range-54 ℃ to + 177 ℃ (see EN 3280),their field of application when lubricated with code A grease is limited to + 121 ℃.
