FAG miniature bearing installation indirectly affect the service life of the reason

FAG bearing installation is correct, affects the precision, life and performance. Therefore, the design and assembly department for the installation of the miniature bearing to fully research. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) Check the size of the associated components and finish machining condition; ( 2) Installation; ( 3) Supply of lubricant. ( 4) Cleaning FAG bearings and miniature bearing connection parts; ( 5) After installed FAG bearing inspection; Hope before the installation, just open the FAG bearing packing. Lubricating oil, ordinary also don't have to be clean, but, instrument or high-speed import with FAG bearing, etc. , to wash with clean oil, remove rust inhibitor on the miniature bearing. General grease lubrication, cleaning, not directly fill grease. Also, has the FAG bearing grease sealed, not directly use cleaning. Remove the rust inhibitor FAG bearing, easy to rust, so can't place. When installed on the shell, clearance fit more commonly, outer ring have surplus quantity, usually use the pressure into the press and or have shrink fit method of cooling after installation. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of FAG bearings. So, need a good rust prevention measures. FAG bearing installation method, owing to the different condition of miniature bearing structure, fit and, in general, as more as the axis of rotation, so the inner circle need interference fit. Taper hole, installed directly on the taper shaft, or use the socket installation. Cylindrical hole bearing, multi-purpose press pressure into, or multi-purpose hot charging method.
