In order to meet the installation requirements of the test equipment, the shaft system must be hollow, and the hollow diameter can reach about 600mm. The double-row thrust angular contact ball bearing adopts a two-way 60° contact angle and a double-row ball structure design, which can withstand radial loads, bidirectional axial loads and overturning moments. It also has the characteristics of high strength and low frictional moment, and is especially suitable for large hollow Shaft support. Conventional double-arranged thrust angular contact ball bearings have separate inner rings and integral outer rings. This design requires adding a main shaft when it is used as a slewing support for the shaft system. Only through high-precision fit and installation between the main shaft and the bearing can it meet the requirements. Its high-precision rotary requirements. However, increasing the main shaft while ensuring a certain hollow diameter will increase the diameter of the bearing, which will increase the manufacturing cost and difficulty of the bearing. At the same time, due to its high precision, the added main shaft also needs to provide a hollow space, and the main shaft also needs to be high. manufacturing cost.
