Self-aligning ball bearings

Self-aligning ball bearings are a type of rolling bearing with self-aligning functionality, consisting of an inner and outer ring, rolling elements (steel balls), and a cage (ball retainer). Unlike other types of rolling bearings, self-aligning ball bearings have a certain degree of self-aligning ability. When there is deviation or misalignment between the shaft and the bearing seat, they can withstand the deviation load by adjusting the balls and cage, ensuring the normal operation of the bearing. Self-aligning ball bearings have the characteristics of large load capacity, smooth rotation, and good wear resistance, and are widely used in the fields of metallurgical equipment, mining machinery, heavy machinery, water pumps, shipbuilding, petrochemical equipment, and others. Additionally, self-aligning ball bearings have advantages such as wear resistance, corrosion resistance, and smooth rotation, which can improve the reliability and service life of mechanical equipment.

We produce self-aligning ball bearing mainly through the following steps:

1. Material preparation: The material used for Self-aligning ball bearings is usually high-quality steel, such as GCr15. During the production process, the material undergoes chemical composition analysis, metallographic examination, hardness testing, and other procedures to ensure that the quality of the material meets the requirements.

2. Cutting processing: The selected raw material is cut to the specified length and preliminarily shaped for subsequent processing.

3. Heat treatment: To improve the hardness, strength, and toughness of the steel, it is subjected to heat treatment. Quenching and tempering processes are commonly used to achieve the desired performance indicators.

4. Cold processing: The material after heat treatment requires cold processing, which mainly includes processing the steel balls, stamping the cage, and turning the inner and outer rings. Common cold processing techniques include turning, grinding, gear grinding, and gear rolling.

5. Precision processing: The various components that have undergone cold processing are precision machined, including grinding the inner and outer rings and the cage, and polishing the balls to ensure the precision and quality of the bearing.

6. Assembly: The precision-machined inner and outer rings, cage, and balls are assembled using special machines and adjusted and lubricated. During assembly, each part's size and relative position must be strictly controlled to ensure the performance and service life of the Self-aligning ball bearings

7. Inspection: After assembly, the Self-aligning ball bearings need to be inspected. Common inspection techniques include visual inspection, dimension measurement, torque testing, noise testing, and more. Only spherical roller bearings that have passed rigorous inspection can be sold.

8. Packaging and shipping: The self-aligning ball bearings that has 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.
