Hybrid ceramic ball bearings

Hybrid ceramic ball bearings are made of bearing steel and silicon nitride (ceramic) balls precisely matched together.
The contact Angle of the hybrid ceramic ball spindle bearing is C= 15° (suffix C) or AC = 25°
Limited by the sealing ring and cage material, the bearings are suitable for operating temperatures of -30℃ To +100℃
In addition, compared with ordinary spindle bearings, hybrid ceramic ball bearings have 50% higher speed, less friction and heat, corrosion resistance, and longer working life.
The main hybrid bearings are 7000 series, 7200 series and 71900 series. The pairing mode is universal U, DB, DT, DF,  TBT, TFT, TTL, QBC, QFC, QT, QBT, QFT,PBC.
