(1) low noise requirements of the rolling bearing
In our production of standard bearings, some single row radial ball bearings and short cylindrical roller bearings for the motor bearing the use of low-noise varieties. Which ball bearings from the diameter φ2.5mm to φ60mm there are several varieties with Zl, Z2 and Z3 three suffix, corresponding to three different low-noise requirements, and roller bearings from N309 to N322-type eight models are also available Manufactured according to low noise standards.
These bearings can be applied to other low noise requirements of the machine, and the price is cheap, as in the type and size to meet the requirements, try to use these two types of low noise bearings.
(2) the use of relatively small noise bearings
When the above two types of low-noise bearings can not be used, relatively quiet bearings can be used. The specific comparison is as follows:
1) The noise of the ball bearing is lower than that of the roller bearing, and the relative (slip) noise of the bearing is less than that of the bearing with relatively more sliding;
2) the use of solid cage bearing noise relative to the use of stamping cage bearings lower; the use of plastic cage bearing noise than the use of the above two cage bearings are low; ball number, the outer ring thick, noise Also smaller,
3) high precision bearings, in particular the use of rolling bearings with higher accuracy, the noise than the low-precision bearing noise is relatively small,
4) small bearing noise than the large bearing noise is relatively small.
