6403 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 6403 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 6403 bearing in English:

1. General Description:

• The 6403 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 due to its robust design。

2. Technical Specifications:

• Bore Diameter (d): 17 mm

• Outer Diameter (D): 62 mm

• Width (B): 17 mm

• Basic Dynamic Load Rating: 22.9 kN

• Basic Static Load Rating: 10.8 kN

• Reference Speed: 28,000 RPM

• Limiting Speed: 18,000 RPM

• Weight: Approximately 0.27 kg。

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 6403 bearing is available with an open design, which means it does not have seals or shields to retain lubricant or exclude contaminants。

4. Applications:

• The 6403 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. Benefits:

• High Load-Carrying Capacity: The 6403 bearing can support heavier radial loads compared to other types of ball bearings.

• Versatility: It is capable of handling both radial and axial loads simultaneously.

• Low Friction: Designed to operate with minimal friction, making them ideal for high-speed applications.

• Simplified Maintenance: Requires less maintenance compared to other types of bearings, making it ideal for set-and-forget operations。

6. Quality Assurance:

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

The 6403 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
