1. NSK bearing oil bath lubricant bath lubrication is the most common lubrication method in NSK bearings; suitable for lubrication of low and medium speed bearings. Part of the NSK bearing is immersed in the groove; the lubricating oil is brought up by the rotating bearing parts; The oil surface that flows back to the oil sump should be slightly lower than the center of the lowest tumbling body.
2. The NSK bearing's drip lubrication drip lubrication is suitable for NSK bearing parts that need to supply lubricating oil quantitatively; the amount of dripping is suitable for every 3-8 seconds; too much oil will lead to higher bearing temperature.
3. The NSK bearing's circulating oil lubrication pump delivers the filtered oil to the NSK bearing components; the lubricating oil after the bearing is filtered and cooled for use. Since the circulating oil can take away a certain amount of heat; the bearing is cooled; therefore, the method is used for the speed. Higher bearing components.
4. The spray lubrication of NSK bearings uses a monotonously shortened air to form an oil mist through the sprayer and the lubricating oil. It is used in the NSK bearing; the air flow can effectively cool the bearing and prevent the intrusion of impurities. This method is suitable for the lubrication of high-speed and low-temperature bearing parts. .
5. The NSK bearing's radiation lubrication pump pumps low-pressure oil through the nozzle into the NSK bearing; the oil injected into the bearing flows into the oil groove through the other end of the bearing. When the bearing rotates at high speed; the roll and cage are also rotated at an equal high speed. The surrounding air forms a gas flow; it is difficult to send the lubricating oil to the bearing by a single lubrication method; at this time, the lubricating oil must be sprayed into the bearing by low-pressure radiation; the position of the nozzle should be placed between the inner ring and the center of the cage.

The ceramic ring is a new type of material formed by Zirconia Ceramic material and sintered. The ceramic ring of Zirconia Ceramic Ring forming process is formed by grade pressure or dry pressing, and can be sintered at high temperature into ceramic rod blank. Finished by polishing, chamfering, fine grinding, etc.; the outer diameter of the ceramic ring can be up to 200mm, and the dimensional accuracy can be accurate to 0.001mm.
