6217c3 bearing

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 6217C3 bearing is a single-row deep groove ball bearing with a medium-size, widely used across various industries due to its ability to handle radial and axial loads. Here is a detailed introduction to the 6217C3 bearing in English:

1. General Description:

• The 6217C3 bearing is designed to accommodate moderate radial loads and some axial loads in both directions. The "C3" designation indicates that this bearing has a clearance greater than the normal (CN) clearance, which is suitable for applications requiring higher speeds or where there are issues with operating temperatures.

2. Technical Specifications:

• Bore Diameter (d): 85 mm

• Outer Diameter (D): 150 mm

• Width (B): 28 mm

• Dynamic Load Rating (Cr): Approximately 85.5 kN

• Static Load Rating (C0r): Approximately 68.5 kN

• Reference Speed: Varies depending on the specific bearing design and lubrication conditions

• Limiting Speed: Also varies depending on design and lubrication, but typically suitable for high-speed applications

3. Design Features:

• The bearing has a deep groove raceway design that provides a large load-carrying capacity and allows for high-speed operation.

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

• The C3 clearance provides a balance between high-speed performance and the ability to handle thermal expansion, which can be beneficial in high-temperature or high-precision applications.

4. Applications:

• The 6217C3 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:

• For open versions, regular lubrication and inspection are necessary to ensure optimal performance and longevity.

• Sealed versions 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 6217C3 bearing comes in various variants, including those with different sealing options, such as the 6217-2RS1 version, which has two rubber seals, providing protection against contaminants and helping to retain lubricants.

8. Quality Assurance:

• Bearings from reputable manufacturers undergo rigorous quality control processes to ensure they meet the highest standards of performance and reliability.

The 6217C3 bearing's combination of high load ratings, high-speed capabilities, and C3 clearance make it a popular choice for a wide range of applications where reliability and performance are critical.
