.jpg)
Ningbo BCH S6900 series stainless steel bearings and plain bearings compared, not only material have obvious advantages, and in the process, control precision, than ordinary bearing to the more stringent. In the work process of stainless steel bearing stable, low noise, corrosion resistance, wide range of applications.
Characteristics of stainless steel products:
Baichuan bearing rings and rolling body material using AISI SUS440C stainless steel (domestic numbers: 9Cr18Mo, 9Cr18) by vacuum quenching and tempering processing, holder and sealing ring skeleton materials used AISI304 stainless steel (domestic numbers: 1Cr18). Compared with plain bearing steel, the stainless steel bearing has better corrosion resistance, corrosion resistance, suitable lubricant and dust cover, and can be used in the environment of -60 C ~+300.
Main uses: medical equipment, low temperature engineering, optical instrument, high speed machine tool, high speed motor, printing machinery, food processing machinery and other fields.
