NTN bearing is one of the imported bearings. How to properly lubricate NTN bearings during normal operation is also an important part of NTN bearing maintenance and maintenance.
1. The oil bath of NTN bearing is smooth
Smooth oil bath is the most common smoothing method in NTN bearings, suitable for the smoothness of low and medium speed NTN bearings. The NTN bearing is partially immersed in the groove, the smooth oil is brought up by the rotating NTN bearing part, and then flows back to the oil groove oil surface should be slightly lower than the center of the lowest rolling element.
2. Smooth drop of NTN bearing
Smooth drip is suitable for NTN bearing parts that need to be supplied with smooth oil. The amount of oil drops is preferably every 3-8 seconds. Excessive oil quantity will cause NTN bearing temperature to increase.
3. NTN bearing's circulating oil is smooth
The oil is pumped to the NTN bearing component by an oil pump, filtered and cooled by the smooth oil after the NTN bearing. Because the circulating oil can take away a certain amount of heat and cool the NTN bearing, this method is used for NTN bearing components with higher speed.
4. Smooth spray of NTN bearings
The boring shrinking air is mixed with the smooth oil by the sprayer to cause oil mist. In the NTN bearing, the airflow can effectively cool the NTN bearing and avoid the intrusion of impurities. This method is suitable for the smoothness of high speed, low temperature NTN bearing components.
5. Smooth radiation of NTN bearings
The low pressure oil is injected into the NTN bearing through the nozzle by the oil pump, and the oil injected into the NTN bearing flows into the oil groove through the other end of the NTN bearing. When the NTN bearing rotates at a high speed, the rolling elements and the cage also cause airflow around the surrounding air at a relatively high rotational speed. It is difficult to send the smooth oil to the NTN bearing in a single smooth manner, which must be smoothed by low-pressure radiation. The oil is sprayed into the NTN bearing and the position of the nozzle should be placed between the inner ring and the center of the cage.
