1, with low noise rolling bearing are: Production in China standard bearing, single row radial ball bearings and cylindrical roller bearing with low noise varieties for machine bearings. The ball bearing inside diameter Phi Phi from 2.5mm to 60mm have several varieties with Zl, Z2 and Z3 three kinds of suffixes, corresponding to the three kinds of low noise of different requirements, and roller bearings from type N309 to type N322 eight models have made according to the standard varieties of low noise. The FAG bearing imports can apply to the other requirements of the low-noise machines, and the price is cheap, such as on the type and size to meet the requirements, as far as possible the use of these two types of low noise bearing.
2, using the bearing noise is relatively small: when low noise bearings can use these two types, can be used FAG bearing imports relatively small noise. Comparison on the basis of the specific as follows:
1) the noise of the ball bearings than roller bearing relatively low, FAG import bearings sliding less noise than the (friction) bearing slide relatively more low; the ball more thick, outer ring, the noise is small;
2) noise using solid cage FAG bearing imports relatively than the use of punch retainer bearing low;
3) noise using plastic cage bearing bracket bearing are lower than the use of the above two kinds of maintain;
4) bearing precision is high, especially for FAG import bearing rolling body of higher accuracy, the noise than the low noise precision bearing relatively small;
5) low noise bearing noise is relatively smaller than bearing.
