Silicon nitride ceramic all NSK bearings, bearings of knowledge

Silicon nitride ceramic all NSK bearing ring and roller adopts silicon nitride ( 文中介绍) Ceramic materials, keep using ptfe ( PTFE） As standard, also can use RPA66 - general 25, PEEK, PI, and phenolic fabric bakelite tube, etc. SiN4 system all NSK compared import bearing ZrO2 ceramic materials can be applied to a higher speed and load capacity, and is suitable for the higher ambient temperature. At the same time can provide rigid precision ceramic bearing spindle used for high speed and high precision high, the highest manufacturing accuracy of P4 to level UP.
