The main shaft bearing is a single row angular contact ball bearing composed of an inner ring, an outer ring, a ball and a solid window cage. Bearings are divided into open and sealed designs.
The tolerance range of the main shaft bearing is very small. They are ideal for bearing arrangements with high guiding accuracy and high speed. They proved to be very suitable for machine spindle bearing arrangements.
The main shaft bearing can withstand unidirectional axial and radial forces. Spindle bearings arranged in O and X shapes can withstand bi-directional axial forces and torques. Spindle bearings arranged in series can only withstand axial forces in one direction.
Limited by the sealing ring and cage material, the bearings are suitable for operating temperatures of -30 °C
To +100 degrees Celsius.
HXB high-speed spindle bearing is a single row angular contact ball bearing with sealing structure added on the basis of the spindle bearing, and the sealing material is mainly NBR rubber.
The contact Angle of high-speed spindle bearings 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.
Hybrid ceramic ball bearings are made of bearing steel and silicon nitride (ceramic) balls precisely matched together.
