Cylindrical roller bearings skf use common sense

 1 Caution is rolling precision parts, so when in use require a corresponding cautious, even if the use of high-performance bearings, if used improperly, they can not achieve the expected performance results, so use should pay attention to the following matters bearing :
1.1 maintain the bearing and its surroundings clean. Even smile invisible dust into the bearing, will increase the bearing wear, vibration and noise.
1.2 when using the installation carefully, do not allow a strong punch, does not allow a direct hit with a hammer bearing, not pass through the rolling pressure.
1.3 Use appropriate and accurate installation tools, make use of special tools, try to avoid using fabric and staple fibers and the like.
1.4 to prevent corrosion of bearings, bearing direct hand pick, to fully wash hands sweat, and coated with high-quality mineral oil before, during the rainy season and summer with particular attention to rust.

2.1 The choice of rolling Backing bearings with inner diameter and outer diameter tolerances are manufactured in accordance with the standard, the bearing inner ring and the shaft, the outer ring and housing bore with the tightness of the journal can only be controlled housing bore tolerances and tolerances to be achieved. Bearing inner ring and the shaft hole basis with the use of the bearing outer ring and housing bore with the introduction of machine axis system. Rolling with commonly shown in Figure 2-1. With the correct choice, you must know the actual load bearing conditions, temperature and other requirements, and in fact it is very difficult. Therefore, in most cases is selected according refinements fit.
