Lubrication and Maintenance of NSK Bearings

 NSK bearing oil bath smooth

Oil bath smoothing is a common smoothing method in NSK bearings, suitable for low and medium speed bearings. A part of the NSK bearing is immersed in the oil groove. The smooth oil is carried by the rotating bearing parts, and then flows back to the oil groove. The oil level should be slightly lower than the center of the lowest rolling body.  For example NSK 6001ZZCM bearing , if need ,click here  


NSK bearings drip smooth

Dripping oil is suitable for NSK bearing parts that require quantitative oil supply. The amount of dripping oil is preferably one drop every 3-8 seconds. Excessive amount of oil will cause the bearing temperature to increase.

NSK bearings have smooth circulating oil

The filtered oil is delivered to the NSK bearing parts with an oil pump, and the smooth oil after passing through the bearing is filtered and cooled before being used. Because the circulating oil can take away a certain amount of heat and cool the bearing, this method is actually used for bearing components with higher speeds.

NSK bearing spray smooth

The oil mist is caused by mixing boring contraction air with smooth oil through a sprayer, and the radiation in NSK bearings can effectively cool the bearings and prevent the intrusion of impurities. This method is suitable for the smoothness of high-speed and low-temperature bearing components.

Radial smoothing of NSK bearings

Use the oil pump to shoot the low-pressure oil into the NSK bearing through the nozzle, and the oil injected into the bearing flows into the oil groove through the other end of the bearing. When the bearing rotates at a high speed, the rolling elements and the cage also cause the surrounding air to cause airflow at a relatively high rotation speed. It is difficult to send the smooth oil to the bearing by individual smoothing methods. At this time, the low-pressure radiation must be used to spray the smooth oil. To the bearing, the position of the nozzle should be placed between the inner ring and the center of the cage.
