1, deep groove ball bearing: Deep groove ball bearing has the advantages of simple structure, low cost and large radial bearing capacity, but it is not suitable for bearing axial load.
2. Angular contact ball bearing: Angular contact ball bearing is complex in structure, but it can bear radial and axial loads and is suitable for high-speed shafts.
3. Tapered roller shaft: Tapered roller bearings are suitable for low-speed heavy-duty bearings and can also bear radial and axial loads. These bearing types are widely used in small and medium-sized CNC machine tools, and the specific choice depends on the design requirements and working conditions of the machine tool.
