As a high-speed running device, the rotating speed of the horizontal decanter centrifuge is usually up to 3000-5000rpm, so that the rolling bearings in the bearing seats at the two ends of the rotating drum must be well and sufficiently lubricated, and the bearings can be ensured to run normally. Lubrication has important effects on the fatigue life, friction, abrasion, temperature, vibration and the like of the rolling bearing, and the bearing cannot work without normal lubrication. Analysis showed that about 40% of bearing damage was associated with poor lubrication. Thus, good lubrication of the bearing is an effective measure to reduce friction and wear inside the bearing. In addition, the lubrication of the bearing has the functions of heat dissipation, rust prevention, sealing, impact alleviation and the like.
