Rolling bearing is an important mechanical component. Whether the function of a mechanical equipment can be fully played depends on whether the smoothness of the bearing is appropriate. Smoothness is the necessary condition to ensure the normal operation of the bearing. No matter what kind of smoothing method is selected, smoothing can play the following effects in rolling bearings.

The formation of oil film increases the touch area and reduces the touch stress. Eliminate conflict heat, reduce bearing operating surface temperature, avoid burns. Dust – proof, rust – proof and corrosion – proof effect. Reduces friction between metals and slows down their wear. Ensure that rolling bearings can work normally for a long time under high frequency touch stress and extend fatigue life.

Therefore, correct smoothing is very important for the normal operation of rolling bearings. The smooth description of rolling bearings mainly includes: the conclusion of a reasonable smooth method, the correct selection of smoothing agent, the quantitative calculation of the amount of smoothing agent and the determination of the oil change cycle. Rolling bearing smoothness can usually be divided into oil smoothness, grease smoothness and solid smoothness according to the type of smoothing agent used.

Including smooth oil has more than the other way to smooth wide temperature range, more suitable for operation under the condition of high speed and high load bearing, because smooth oil also has replace the convenience, the system of equipment protection and smooth agent conflict deputy can smooth together strengths such as gear, so far, the bearing oil very smooth throughout.

Smooth grease has the advantages of simple sealing equipment, low repair cost and low smooth grease cost, which is widely used in bearings of low speed, medium speed and medium temperature operation. In particular, the emergence of anti-wear additives in recent years has improved the smooth function of fat, so that fat smooth has been more widely used. If the use of oil smoothness and grease smoothness can not reach the smooth conditions required by the bearing, or cannot satisfy the specific operating conditions, you can use solid smoothing agent, or try to improve the smooth function of the bearing itself.
