The use of bearings note
Rolling to precision parts, which when in use require a corresponding cautious, not only changed the use of high-performance bearings, if used improperly, they can not achieve the expected performance results, so make use of the bearing should note the following:
, maintain the bearing and its surroundings clean. Smile even if invisible dust into the bearing will increase bearing wear, vibration and noise
, when using the installation carefully, does not allow a strong punch, does not allow a direct hit with a hammer bearing, is not allowed to pass through the rolling pressure.
 Using appropriate and accurate installation tools to make use of special tools, try to avoid using fabric and staple fibers and the like.
 To prevent corrosion of bearings, bearing directly pick by hand, to fully wash hands sweat, and coated with high-quality mineral oil before you start, during the rainy season and summer with particular attention to rust.

Inner diameter and outer diameter of bearing size is made according to standard tolerances, the bearing inner ring and shaft, outer ring and housing bore with the tightness of the journal can only control the seat hole tolerances and tolerance to achieve. Bearing inner ring and shaft system using the base hole, the bearing outer ring and housing bore with the use of machine axis system.
With the right choice, we must know the actual load bearing conditions, temperature and other requirements, but in fact it is very difficult. Therefore, in most cases is based on using the refinements of choice for that.
 The load size
between the ring and shaft or housing depends on winning over the size of the load, the heavier the load the larger amount had to win, the lighter the load using a smaller amount than to win.
