The two-way thrust angular contact ball bearing is composed of two shaft washers, a housing washer with a lubricating oil groove and an oil hole, a spacer ring, two rows of rolling elements and a cage. The clearance and preload of the bearing can be adjusted by grinding the thickness of the spacer. The contact angle of the bearing is 60°, which is used to bear the combined axial and radial load in two directions, mainly the axial load. This type of bearing is widely used in grinding machines, boring machines, lathes, milling machines, drilling machines and other spindles. It is a high-precision bearing specially designed for it. This type of bearing has the advantages of high precision, good rigidity, low temperature rise, high speed, and convenient assembly and disassembly.
