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.

low speed bearing grease
How to use low-noise bearing manufacturer grease seals
class = MsoNormal> foreign low-noise sealed bearings with grease broadly divided into three categories: low speed bearing grease, general low-noise motor bearing grease, high temperature long life low noise slewing ring grease.
Currently, the use of precision bearings with increasing sophistication, and promoting the bearing grease used must have the following properties:
(1) has the same bearing operating life, try to extend the maintenance cycle, reduce downtime, improve labor productivity.
(2) In the dn> 5 × 105 to ensure that the motor speed under low temperature, do not dump oil, thereby reducing power consumption to protect the motor.
(3) impurity content is controlled at a certain level below the maximum to reduce device noise pollution to the environment.
(4) in the ultra-low temperature operating conditions to ensure the flexibility of starting and running bearings ensure minimum output power.
2 Universal low-noise motor bearing grease
In the bearing industry, the application of this grease the largest amount of total fat content of 70% with. As these greases selected fiber is soft, easily filtered lithium soap thickener made??, the use of mineral oil as base oil, it is easy to meet lower middle and low bearing vibration requirements. Another advantage is a good pumping, whether mechanical grease, or hand-painted resin, are easy.
