Rolling bearings with low noise requirements

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. Among them, the ball bearings from 2.5 mm to 60 mm have several varieties with Zl, Z2 and Z3 suffixes, they correspond to three different low noise requirements, and there are eight types of roller bearings from N309 to N322 manufactured according to low noise standards.

These bearings can be applied to other low noise requirements of the machine, and cheap, such as in the type and size can meet the requirements, try to use these two types of low noise bearings.

Use bearings with relatively low noise

When the two types of low noise bearing can not be used, the use of relatively low noise bearings. The specific basis for comparison is as follows:

1 The noise of ball bearings is lower than that of roller bearings, the friction noise of bearings with less sliding is lower than that of bearings with more sliding;

2 the noise of bearings with solid cage is lower than that of bearings with punched cage; the noise of bearings with plastic cage is lower than that of bearings with the two kinds of cages;

3 the noise of bearings with more balls, thicker outer ring and lower noise is lower than that of bearings with high precision, especially bearings with more precision of rolling body, its noise is lower than that of bearings with low precision;

4 the Noise of small bearings is lower than that of large bearings.
