Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.

has to prevent metal corrosion lubricant effect
Describes the importance of imports bearing lubrication and effect
Lubrication of the bearings, in particular, the fatigue life of the rolling bearing manufacturer and friction, wear, temperature, vibration, etc. have a major impact. Without proper lubrication, the bearings will not work. Analysis to understand: Bearing causes of damage showed that about 40% of the bearing damage are related with poor lubrication. Therefore, well lubricated bearings is to reduce bearing friction and wear of effective measures.
Bearing lubrication effects can be briefly described as follows:
1 using oil lubrication, especially the use of circulating oil lubrication, oil mist lubrication and injection lubrication, the lubricant inside the bearing can take away most of frictional heat, serve as an effective heat sink.
2 in the rolling Bearing test machine contact with each other or the two form a film between the sliding surfaces of the second surface spaced from the contact surface to reduce friction and wear.
3 has to prevent metal corrosion lubricant effect.
4 lubricated with grease, you can prevent external dust and other foreign matter from entering the bearing, and sealing effect.
5 to extend the fatigue life of bearings.
