Table 4-1 Domestic and foreign standard systems of self-lubricating joint bearings and bushings

 

After years of research and development of self-lubricating joint bearings and self-lubricating bushings, our company has the ability to produce bearing products that meet the standards in Table 4-1.

In recent years, in order to continuously meet the needs of users, our company has gradually increased the study of foreign advanced bearing factories. For the bearing products of foreign samples (such as SARMAA, SKF, etc.), our company has the same production level and has repeatedly solved the urgent needs of users.
