12、10 EN 3061:20073 Foreword This document (EN 3061:2007) has been prepared by the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN). After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the

13、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, either by publication of an identical text or by endorsement, at the latest by December 2007, and conflicting nat

14、ional standards shall be withdrawn at the latest by December 2007. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CE

15、N/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

16、Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. EN 3061:20074 1 Scope This standard specifies the characteristics of rigid single row ball bearings in corrosion resisting steel with a solid or lightweight flang

17、ed alignment housing, designed to withstand only slow rotations and slight 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 temperat

18、ure range from 54 C to 150 C. However, being lubricated with the following 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

19、 C to 177 C. Their field of application when lubricated with code letter A grease is limited to 121 C. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the l
