Angular Contact Ball Bearings

Angular contact ball bearings are a type of high-precision rolling bearing composed of an inner ring, an outer ring, a cage, and steel balls. The inner and outer rings of angular contact ball bearings are both arc-shaped, and their geometric centers do not coincide, giving the bearing the characteristic of contact angle. The steel balls are placed between the inner and outer rings and are arranged equidistantly through the cage. When subjected to loads, the steel balls can roll freely, allowing the bearing to withstand loads and moments in multiple directions. Additionally, the free rolling of the steel balls results in relatively low friction and noise.

The seals of angular contact ball bearings can prevent dust and water, maintain lubricating oil inside the bearing, and prevent external impurities from entering. This can prolong the service life of the bearing and improve its performance.

We produce angular contact ball bearing mainly through the following steps:

1. Raw material preparation: The manufacture of angular contact ball bearings requires the selection of high-quality bearing steel materials, typically GCr15. These raw materials need to undergo strict chemical composition analysis and mechanical property testing to ensure that the quality and performance of the materials meet the requirements.

2. Heat treatment: Through forging, quenching, tempering, and other heat treatment processes, the bearing steel material is given excellent mechanical properties and wear resistance. This is one of the critical steps in bearing production.

3. Cold drawing and tube making: Using the cold drawing and tube making process, the heat-treated bearing steel material is made into steel pipes with diameters and wall thicknesses that meet the requirements. This step requires precise control of the accuracy and surface quality of the tubes.

4. Bar turning: The bearing steel material made into steel pipes is cut into appropriate lengths of cylinders, then rough ground and precision ground, and finally turned into cylinders with diameters slightly larger than the required inner and outer rings. This step requires precise control of dimensions such as roundness and straightness.

5. Ball processing: The bearing steel material is made into balls with diameters that meet the requirements, generally using processes such as cold extrusion of steel balls, steel ball grinding, and steel ball hot pressing. This step requires precise control of sphericity and surface quality.

6. Precision machining: Using precision machining equipment such as CNC machine tools and grinders, the inner and outer rings and balls are precisely machined to ensure the geometric accuracy and surface quality of the angular contact ball bearings. This step includes precision grinding of the inner and outer rings, ball and inner/outer raceway matching, and control of the clearance fit.

7. Assembly: The inner and outer rings and balls are assembled together, and the retaining cage and sealing device are installed to form a complete angular contact ball bearing. This step requires strict control of assembly quality and clearance to ensure bearing performance.

8. Inspection: Multiple inspections are performed on the produced angular contact ball bearings, including visual inspection, dimension measurement, and hardness testing, to ensure product quality. Only products that meet the inspection requirements can proceed to the next step of sales and use.

9. Packaging and shipping: The angular contact ball bearings that have undergone quality inspection need to be packaged to protect them from damage. Common packaging materials include cartons, wooden boxes, and pallets. Finally, the products can be shipped to customers by sea, air, or land transportation.
