6210 50mmX90mmX20mm

6210 bearing is a common deep groove ball bearing, with an inner diameter of 50 millimeters, an outer diameter of 90 millimeters, and a width of 20 millimeters. It is mainly composed of inner and outer rings, steel balls, a cage, and a seal ring. The inner ring is a ring-shaped part that is installed on the shaft and fits with the shaft; the outer ring is a ring-shaped part that is installed on the bearing seat and fits with the seat. The steel balls roll between the inner and outer rings, supporting and rotating the shaft through rolling friction. The cage is used to maintain the relative positions of the steel balls, ensuring the stability of the bearing and reducing noise. The seal ring is used to prevent dust and water from entering the bearing, protecting the bearing from contamination.
6210 bearing is commonly used in high-speed and high-load applications. Its design allows it to withstand radial and axial loads while having relatively low friction losses and high rotational speeds. In addition, it also has high durability and a long lifespan.

We Produce Deep Groove Ball Bearings video

We produce 6210 bearing have the following characteristics:

1、High Load Capacity: Our 6210 bearing has a static load capacity of 23.2KN and a dynamic load capacity of 35KN, which means it can withstand significant loads and is suitable for applications that require high load capacity.

2、High Speed: Our 6210 bearings can operate at high speeds, and the steel balls inside the bearing provide sufficient support when rotating at high speeds, making them less susceptible to damage, typically up to around 14,000 revolutions per minute.

3、High Precision: Our 6210 bearings are measured and processed with precision for their inner diameter, outer diameter, and width, ensuring proper fit between all internal components and smoother, safer bearing rotation.

4、Long Life: Our 6210 bearings are made of high-quality materials and precision manufacturing processes, with high wear resistance and corrosion resistance. The steel balls inside the bearings reduce internal friction and wear, ensuring long-term stable performance.

5、Good sealing performance: Our 6210 bearings have excellent sealing performance and can be sealed with metal covers, rubber seals, or nylon seals to prevent external dust and impurities from entering the bearing and to prevent grease leakage.

6、Low Noise: The 6210 bearing has a spherical design for the contact area between the ball and the cage, which reduces friction noise when the ball moves axially and radially, resulting in low noise.

7、Wide Applicability: The 6210 bearing has a well-designed structure, strong load-bearing capacity, good speed performance, and low frictional losses. It is suitable for various applications, including motors, mechanical transmissions, automation equipment, agricultural machinery, and machine tools.

We produce 6210 bearing mainly through the following steps:

1. Raw material preparation: High-quality bearing steel such as GCr15 is selected and undergoes chemical analysis and quality testing before entering the production process.

2. Heat treatment: The raw material undergoes heat treatment, including tempering, quenching, and other processes, to change the mechanical properties and structure of the material. These steps help to improve the hardness, strength, and corrosion resistance of the steel.

3. Cold extrusion: The raw material that has undergone heat treatment is cold extruded to make it into a circular bearing outer and inner ring. This process can improve the density and uniformity of the raw material.

4. Grinding and machining: The bearing outer and inner rings are ground and machined to improve dimensional accuracy and surface quality. This step is crucial because the geometric shape and surface quality of the bearing have a significant impact on its performance.

5. Cutting the cage: The cage raw material is cut to shape the cage. The cage's function is to fix the bearing balls and maintain a certain distance when running.

6. Bearing ball manufacturing: Bearing steel is cold or hot forged into spherical bearing steel balls. The size and quality of the bearing balls are also crucial to the bearing's performance.

7. Cleaning and polishing: The manufactured bearing balls are cleaned and polished to improve surface finish and reduce frictional losses. This step can reduce bearing friction and wear, thus extending the bearing's service life.

8. Assembly: The bearing balls, outer and inner rings are assembled together and fixed with a bearing cage. The assembly process requires ensuring the dimensional and quality accuracy of each component to ensure the bearing's performance.

9. Lubrication: Lubricating grease or oil is injected into the bearing's interior to reduce bearing wear and friction. Lubrication can reduce friction between the bearing balls and cage, thus reducing bearing wear.

10. Inspection: Quality inspection of 6210 bearing includes inspection of appearance, dimensional measurement, rolling resistance testing, noise testing, and other aspects. Precision measuring instruments and equipment are used during the inspection to ensure product quality and performance.

11. Packaging and shipping: The 6210 bearing 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.
