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.

Self-aligning ball bearings are bearings capable of bearing large radial and axial loads. The axes of the inner and outer rings intersect at one point, giving them a certain degree of self-aligning capability. The structure mainly includes four parts: inner ring, outer ring, cage, and rolling elements.

1. The inner and outer rings are made of steel and are processed by techniques such as heat treatment and grinding. The inner ring surface generally has a circular groove to better match the rolling elements, reducing friction and wear. The outer ring usually has a spherical groove to accommodate the movement of the rolling elements.

2. The cage is an important component of self-aligning ball bearings. Its role is to fix the position of the rolling elements, allowing them to be evenly distributed between the inner and outer rings while maintaining a certain gap so that the rolling elements do not squeeze or rub against each other during movement. The cage is generally made of copper alloy or engineering plastic.

3. The rolling elements are the core components of self-aligning ball bearings. They roll between the inner and outer rings, bearing axial and radial loads. The rolling elements are usually made of steel and processed by techniques such as heat treatment and grinding to ensure their hardness and accuracy.

We produce self-aligning ball bearing have the following characteristics:

1. Strong self-aligning ability: Self-aligning ball bearings can automatically adjust the position of the inner and outer rings under different loads and speeds, compensating for bearing deviations and providing excellent self-aligning ability.

2. High load-carrying capacity: Self-aligning ball bearings have a special design and manufacturing process that makes them capable of handling high-speed rotation and high loads.

3. High-speed performance: Self-aligning ball bearings have a special geometric structure and surface treatment inside, which can maintain stable operation at high speeds and thus have high-speed performance.

4.Strong adaptability: Due to its self-adaptive ability, Self-aligning ball bearings can be applied to bearing seats of different shapes and precision. This makes it one of the most commonly used types of bearings in the industrial machinery field.

5. Good durability: Self-aligning ball bearings use high-strength steel material and special heat treatment process internally, which can maintain a good service life under long-term high-load and high-speed working conditions.

6. Easy installation: Self-aligning ball bearings have a simple structure and are easy to install, requiring only the inner and outer rings to be separately mounted on the shaft and housing.

7. Wide applicability: Self-aligning ball bearings are suitable for various mechanical equipment, such as metallurgy, mining, heavy machinery, cement machinery, agricultural machinery, construction machinery, and so on.

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

6. 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.

6. 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.
