During use, regular monitoring of external conditions, the basic bearing operation such as temperature, vibration and noise measurement, etc.. These regular checks for early detection of potential problems and will prevent the emergence of beat all machine halt, make production plans to implement, improve plant productivity and efficiency.

In the process of operation, bearings require proper lubrication once again, perfect its performance. Miniature bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing play function very well, first of all, to choose suitable conditions, using the method of lubrication. If only consider lubrication, oil lubrication of lubrication advantage. But the grease around bearing structure can be simplified.

Precision class degrees from 0 levels in order to improve, for general use level 0 is enough, but in Table 1 below condition or situation, requires a level 5 or higher accuracy.

Precision grade above is based on the ISO standard formulation, but its name is different in national standards.

The comparison between the listed a variety of bearing types suitable precision grade and national standard.

Size precision (with the shaft and the shell is arranged on the project)

The allowable deviation of 1, diameter, diameter, width and the width of the assembly

The allowable deviation of 2, roller group round diameter and outer round diameter

3, chamfer dimension admissible limit

4, the width of the permissible variation

The rotating precision (rotating body and beat related projects)

1, the inner ring and the outer ring allows for radial and axial runout

2, the inner ring to allow lateral runout

3, outer diameter surface inclination of the permissible variation

4, the thrust bearing raceway thickness allows variation

The standard form of bearing size range, in the design of mechanical device is best when using standard bearings (this design to the bearing is easy to purchase, here as an aside, some bearing catalog model does, but some non-standard bearing no cash, in China mainland sometimes futures will be very long time, so in the bearing to be considered in the selection of the time cost and the late replacement cost) bearing load, load exerted on the bearing, the nature, size, direction is changeable. Typically, the basic load rating are displayed in the dimension table. Axial and radial loads and so on, is also an important factor for the selection of bearing. When the size of the ball and needle bearing, needle roller bearings typically have a higher load capacity and bear larger vibration and shock loads.
