Selection Skills Of Low Noise Fag Imported Bearings

 

1. Rolling bearings with low noise requirements include:

among the standard bearings produced in China, some single row radial ball bearings and short cylindrical roller bearings have low noise varieties for motor bearings. Wherein, the inner diameter of ball bearing φ 2.5mm to φ 60mm has several varieties with three suffixes of ZL, Z2 and Z3, which correspond to three different low-noise requirements respectively. Among the roller bearings, there are eight models from n309 to n322, which are also manufactured according to the low-noise standard. These fag imported bearings can be fully applicable to other machines with low noise requirements, and the price is cheap. If the type and size can meet the requirements, try to use these two types of low noise bearings.

2. Bearings with relatively low noise:

when the above two types of low noise bearings cannot be used, FAG imported bearings with relatively low noise can be used. The specific comparison basis is as follows:

 

1) The noise of ball bearing is lower than that of roller bearing, and the (friction) noise of fag imported bearing with less sliding is lower than that of bearing with more sliding; More balls, thicker outer ring and less noise;

 

2) The noise of fag imported bearing with solid cage is relatively lower than that of bearing with stamping cage;

 

3) The noise of bearings with plastic cages is lower than that of bearings with the above two cages;

 

4) The noise of high precision bearings, especially fag imported bearings with higher rolling element accuracy, is relatively lower than that of low precision bearings;

 

5) The noise of small bearings is relatively lower than that of large bearings.
