bearing 6211 skf

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

The SKF 6211 bearing is a single-row deep groove ball bearing known for its versatility, low friction, and ability to handle both radial and axial loads in both directions. Here is a detailed introduction to the SKF 6211 bearing in English:

1. General Description:

• The SKF 6211 bearing is designed to accommodate high speeds and is optimized for low noise and low vibration. It is easy to mount and requires less maintenance than many other bearing types.

2. Technical Specifications:

• Bore Diameter (d): 55 mm

• Outer Diameter (D): 100 mm

• Width (B): 21 mm

• Dynamic Load Rating (Cr): 46.2 kN

• Static Load Rating (C0r): 29 kN

• Reference Speed: 14,000 RPM

• Limiting Speed: 9,000 RPM

• Mass: Approximately 0.61 kg

3. Design Features:

• The bearing has a simple, robust design with a single row of deep grooves that accommodate a large number of balls, providing high load-carrying capacity and allowing for high-speed operation.

• It is made from high-quality bearing steel, ensuring durability and reliability.

• The bearing features a cylindrical bore and is available with a steel sheet cage.

4. Applications:

• The SKF 6211 bearing is commonly used in electric motors, pumps, fans, gearboxes, and other machinery where high performance and reliability are required.

• It is suitable for applications in the automotive, agricultural, and industrial sectors where bearings are subjected to dirt, dust, and other contaminants.

5. Maintenance:

• The SKF 6211 bearing requires regular lubrication and inspection for open versions to ensure optimal performance and longevity.

• Sealed versions, such as the 6211-2RS, would require less frequent maintenance due to the sealed design, which helps to reduce the risk of contamination and extends the service life of the bearing.

6. Installation:

• Proper installation is crucial for the bearing's performance and lifespan. It is recommended to use the correct tools and follow best practices to avoid damage during installation.

• The bearing should be cleaned, and the mating surfaces should be free of contaminants before installation.

7. Variants:

• The SKF 6211 bearing comes in various variants, including those with different sealing options, such as the 6211-2RS version, which has two rubber seals, providing protection against contaminants and helping to retain lubricants.

8. Quality Assurance:

• SKF bearings, including the 6211, are known for their high quality and are manufactured to stringent quality standards, ensuring reliability and performance.

The SKF 6211 bearing's combination of high load ratings, high-speed capabilities, and availability in various configurations make it a popular choice for a wide range of applications where reliability and performance are critical.
