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.

Rolling mill bearing Carry out large-scale projects
Proposed two sessions related to economic growth targets , infrastructure around the city began to actively start including road , rail, water , ports, airports and other major urban projects . Carry out large-scale projects , so that the entire domestic construction machinery industry to recover, demand for construction machinery relatively strong , while increasing market demand for bearing a certain extent .
From the data , the current domestic marine ships, automobiles , oil pipelines and so on industry production Rolling mill bearing plans to maintain a certain stability. And bearing a slight increase in construction machinery industry production plans. With the recovery of the construction machinery industry will contribute significantly to the demand for bearings , bearing industry will develop further. Most of the Bearing manufacturing machine bearing steel enterprises to maintain good sales in March , sales growth could help stabilize the entire bearing steel market , promote the rapid development of bearing steel companies.
The current stable development of China's bearing manufacturing industry , market demand for high-end bearing is growing, such as machine tool bearings , aerospace bearings, high-speed precision bearings, wind power bearings, rolling bearings , high-speed rail bearings, turbocharger bearings , and so on .
