EN 4034:20074 1 Scope This standard specifies the chara
17、cteristics of self-aligning double row ball bearings with flanged outer ring in corrosion resisting steel, reduced internal clearance, 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 c
18、ontrol mechanisms. They are intended to be used in the temperature range: 54 C to 150 C. However, being lubricated with the following greases: very high pressure grease, ester type (code A), operational range 73 C to 121 C or very high pressure grease, synthetic hydrocarbons, general purpose (code B
19、), operational range 54 C to 177 C (see EN 3280), their field of application when lubricated with code A grease is limited to 121 C. 2 Normative references The following referenced documents are indispensable for the application of this document.
