Selection Of Low Noise SKF Bearing

 

Rolling SKF Bearing with low noise requirements

Among the standard SKF bearings produced in China, some single row centripetal ball SKF bearings and short cylindrical roller SKF bearings have low noise varieties for motor SKF bearings. The inner diameter of ball SKF Bearing φ 2.5mm to φ 60mm has several varieties with three suffixes ZL, Z2 and Z3, corresponding to three different low-noise requirements respectively. There are also varieties manufactured according to low-noise standards in eight models from n309 to n322 in roller SKF bearings. These SKF 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 SKF bearings.

Selection Of Low Noise SKF Bearing
 
SKF bearings with relatively low noise are used

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

 

1) The noise of ball SKF Bearing is lower than that of roller SKF Bearing, and the (friction) noise of SKF Bearing with less sliding is lower than that of SKF Bearing with more sliding;

 

2) The noise of SKF Bearing with solid cage is relatively lower than that of SKF Bearing with stamping cage; The noise of SKF Bearing with plastic cage is lower than that of SKF Bearing with the above two cages; Those with a large number of balls, thick outer ring and low noise,

 

3) The noise of SKF Bearing with high precision, especially the SKF Bearing with higher rolling element precision, is relatively lower than that of SKF Bearing with low precision,

 

4) The noise of small SKF Bearing is relatively lower than that of large SKF Bearing
