(1) has a low noise requirements FAG Bearings
In our production of standard bearings, some single row radial ball bearings and cylindrical roller bearings have powered machine bearings using low-noise variety. Wherein the ball bearing from φ60mm diameter φ2.5mm to a number of varieties with Zl, Z2 and Z3 three kinds suffix, corresponding to three different low noise requirements, and roller bearing type N309 to N322 from eight types of models have manufactured by low-noise standard varieties.
These FAG bearings can be applied to other low-noise requirements machine, and the price is cheap, as in the type and size can meet the requirements, maximize the use of these two types of low-noise bearings.
(2) use of a relatively small bearing noise
When not using the two types of low-noise FAG bearings, the noise can be relatively small bearings. Specific basis of comparison is as follows:
1) The ball bearing roller bearing noise ratio is low, relative sliding fewer FAG bearing (friction) more noise than the sliding bearing is low;
2) using physical cage FAG bearing noise is comparatively punch bearing cage with low; with plastic cage bearing noise than the above two bearing cage are low; ball a few more, the thickness of the outer ring, noise is small,
3) high precision FAG bearings, especially in the higher precision rolling element bearings, precision bearings noise than the low noise is relatively small,
4) Small FAG bearing noise than large bearing noise is relatively small.
