Single row angular contact ball bearings: it can only bear the axial load in one direction, and the shaft and the shell can only be axially displaced in one direction. It is used in non-separation design, so the inner and outer ring of the shoulder level is not the same, so that you can put more steel balls, thereby enhancing the bearing load capacity.
Double row angular contact ball bearings: it can withstand radial load and axial load, the shaft can be axially displaced in two areas. If there is an inclination angle between the inner and outer rings of the bearing, the bearing life will be affected and the bearing will be lowered in operation and the noise will increase.
2. Precautions
(1) bearing installation, should be selected in a clean and clean environment.
(2) bearing the septum to be ground, the inner and outer ring and the septum to keep climbing, and the parallelism of the septum should be less than 1um.
(3) before the installation of bearings to be cleaned, and to clean, dry and then lubricated. Use special tools to install, can not be beaten.
(4) bearing a long time storage, should be carried out on a regular rust, to prevent rust.
3. Maintenance
When the bearing is running for a period of time, it should be removed for cleaning, and check whether the damage or damage, and whether the loose and wear, if it should be handled and resolved, can not be repaired. After cleaning and then lubrication, lubrication and then re-assembly up.
