1. Rolling bearings with low noise requirements are: in the standard bearings produced in China; some single-row radial ball bearings and short cylindrical roller bearings have low noise types for power supply bearings. The ball bearings are from the inner diameter φ2. 5mm to There are several types of φ60mm with three suffixes of Zl, Z2 and Z3; there are three different low noise requirements; the eight types of roller bearings from N309 to N322 also have low noise specifications. These bearings are perfectly suited for use in other machines with low noise requirements; and they are inexpensive; they meet the requirements in terms of type and size; try to use these two types of low noise bearings.
2. Use bearings with relatively low noise: When the above two types of low-noise bearings cannot be used; bearings with relatively small noise can be selected. The detailed comparison is as follows:
1) The noise of the ball bearing is lower than that of the roller bearing; the (collision) noise of the bearing with less sliding is lower than that of the relatively sliding bearing, and the number of balls is large; the outer ring is thick; the noise is also higher.
2) The noise of the solid cage bearing is relatively lower than that of the bearing using the stamping cage.
3) The noise of the plastic cage bearing is lower than that of the bearings of the above two cages.
4) Bearings with high precision; especially the bearings with higher precision of the rolling body; the noise is relatively better than the noise of low-precision bearings.
5) The noise of small bearings is relatively small compared to the noise of large bearings.

Sintered Alnico made by powder metallurgy method of production, for production of complex shape, light, thin, small products,
 widely used in instrumentation, communications, magnetic switches and various sensors.

Unlike cated Alnico Magnets, sintered Alnico magnets(sintered Alnicos) offer lower magnetic properties but better mechanical characteristics. Mixes of metal powders are pressed to shape and size. The sintering process is well suited to large volume production, and results in parts that are structurally stronger than cast Alnico magnets. Relatively close tolerances can be achieved without grinding.

Application of  Sintered Alnico  magnets:
•Electronic ignition systems
•Volt-amp meters
•Industrial motors
•Vending machines
•Watt bour meters
•Medical instruments
•Magnetic reed switches
