After enquiries and votes c
13、arried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, eithe

EN 4034:20074 1 Scope This standard specifies the char
17、acteristics 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
18、control 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
19、B), 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.
