Bidirectional Thrust Angular Contact Ball Bearings

★　Product Characteristics

Bidirectional Thrust Angular Contact Ball Bearing comprises two blowout patches, a seat ring with lubricant slot and lubricant hole, a space ring, two rows of roller bodies and holders. Clearance and preload of the bearing can be adjusted by grinding the thickness of the space ring. The contact angle is 60°, and the bearing is used to be subject to axial and radial combination load in which the axial load is the main load. This type of bearing is widely applied on main shaft of grinder, boring mill, turning mill, milling machine and drill machine etc. It is specialized high precision bearing for these equipments. This type of bearing has advantages of high precision, good rigidity, low temperature rise, high speed and convenient loading and unloading.
