The choice of low noise FAG bearings - bearing knowledge

( 1) Move FAG bearings with low noise requirements the scale FAG bearings produced in China, the department of short single FAG centripetal ball bearings and cylindrical roller FAG bearing FAG bearing for motor of low noise varieties. The ball FAG bearings from inner diameter phi 2. 5 mm to phi 60 mm have several varieties with Zl, Z2 and Z3 three suffixes, corresponding to three different types of low noise, and FAG bearing in the roller type N309 to N322 eight models according to the variety of low noise scale manufacturing. These FAG bearings can used in other machine with low noise requirements, and the price is cheap, as on the type and size can be request, try to use the two types of low noise FAG bearings. ( 2) Using relatively small FAG bearing noise when not using the above two types of low noise FAG bearings, FAG bearing can use noise is relatively small. A detailed comparison on the basis of the following: 1) Ball FAG bearing noise is lower than that of the roller bearing, the relative sliding fewer FAG bearing ( Friction) The noise is lower than relative sliding more FAG bearings; 2) Using entity maintains a FAG bearing noise is relatively lower than using stamping maintains a FAG bearing; Using the plastic cage FAG bearing noise than using the above two FAG bearing cage is low; The count more, the outer ring thickness, noise is small, 3) High precision FAG bearing, especially the move precision higher FAG bearing body, its noise than low precision FAG bearing noise is relatively small, 4) Little FAG bearing noise than the big FAG bearing noise is relatively small. For example, the centripetal ball bearing noise is smaller than short cylindrical roller bearing, short cylindrical roller bearing noise and smaller than the noise of the tapered roller bearing.
