When assembling the joint bearing series, it is necessary to pay special attention to the location of the outer surface of the split. Consistent with a direct role in order to avoid the cut surfaces, the need to maintain the dividing surface at right angles to the direction of thin wall bearings compliance.
Lubricating
When the applied load and the speed of the swing movement generated by the very hour, to the oil-type spherical plain miniature ball bearings can operate without lubrication conditions. Nevertheless, under normal circumstances have to be jacked up to add grease. Operation during the initial installation, it is recommended lubrication intervals should be moderately reduced.
Circumstances non-oil type joints lubricated bearings can no longer use the following. However, if before the operation adding lithium soap grease, use the Needle Roller Bearing term joint bearing stresses may be more prolonged. If injected into the space around the bearing grease, bearing joints will be more effective protective dust and foreign matter intrusion.
