    Selection of low-noise bearing

    (1) low noise requirements of the rolling bearing

    Of standard bearing part of the single row radi al ball bearings and a short cylindrical roller bearings powered machine bearings used in low noise varieties. In which the ball bearings from the inside diameter φ2.5mm to φ60mm several varieties with Zl, Z2 and Z3 three suffix, corresponding to three different low-noise requirements, and roller bearings from a total of eight models of the N309 type N322 type varieties manufactured by low-noise standards.slewing bearing suppliers

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

    (2) noise is relatively small bearing

    When you can not use these two types of low-noise bearing, can be relatively small bearing noise. The specific ba sis of comparison are as follows:

    Noise ratio of 1) ball bearings, roller bearings is low, the relative sliding fewer bearings (friction) noise more than the relative sliding bearing;

    2) the use of entity cage bearing noise than using stamping cage bearings; the use of plastic cage bearings noise is lower than using the above two bearing cage; the number of balls, thick outer noise is also smaller,

    3) high precision bearings, especially the higher precision of rolling element bearings used in the noise than the noise of the low-precision bearings are relatively small,

    4) bearing noise than a large bearing noise is relatively small.china bearing
