How to choose the method of bearing low noise

Wafangdian spherical roller bearing Bearing - comfortable and durable Talking with you on June 29, the author how to choose the method of bearing low noise: 1. Rolling bearings with low noise requirements in the national standards of production of bearings, part of the single row centripetal ball bearings and spherical roller bearings are for the use of motor bearing varieties of low noise. From inside diameter of ball bearing & phi; 2. 5 mm & phi; 60 mm have several varieties with Zl, Z2 and Z3 three suffixes, corresponding to three different types of low noise, and roller bearing from N309 type to N322 type, a total of eight models have made according to standard low noise. These bearings can apply to other machines with low noise requirements, and the price is cheap, as on the type and size can be request, try to use the two types of low-noise bearings. 2. How to choose the bearing low noise method 2: when you can't use these two types of low noise bearings, bearing can use noise is relatively small. Specific comparison basis is as follows: 1) The noise of the ball bearing is lower than that of the roller bearing, relatively less sliding bearing ( Friction) More noise than the relative sliding bearing is low; 2) Using solid cage bearing noise is relatively lower than using punching cage bearing; Using the plastic cage bearing noise than using the above two cage bearing are low; The count more, the outer ring thickness, noise is small, 3) High precision bearings, especially the higher precision of the rolling element bearing, its noise than the low precision of bearing noise is relatively small, 4) Small bearing noise than the big bearing noise is relatively small. Bearing comfortable and durable, )
