Self-aligning Ball Bearing 13944 Durable for Industrial Applications

Self-aligning ball bearing
Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.

    Accommodate static and dynamic misalignment
    Excellent high-speed performance
    Excellent light load performance
    Low friction

Knowledge and introduction of bearings

The 13944 Automatic Self-Aligning Ball Bearing is designed to provide reliable performance in applications requiring load handling capabilities, precise alignment, and high durability. Here’s a detailed overview of its technical parameters and features:

Key Specifications:

1. Type: Automatic Self-Aligning Ball Bearing

• This bearing is designed to automatically correct misalignment, making it ideal for applications where shaft alignment may vary due to installation errors or operational conditions.

2. Dimensions:

• Bore Size: Typically 20 mm to 240 mm, with custom sizes available upon request.

• Outer Diameter: Varies depending on the specific bearing size.

• Width: The width of the bearing also varies according to the size, ensuring compatibility with different shaft configurations.

3. Material:

• The bearing is typically made of high-quality bearing steel (such as GCr15 or AISI 52100), providing excellent wear resistance, high load capacity, and resistance to corrosion.

• It can also be manufactured with stainless steel or other special materials depending on the specific application requirements, such as for harsh environments.

4. Load Capacity:

• The bearing is designed to carry both radial and axial loads, with its self-aligning feature allowing it to handle moderate to heavy loads without the risk of shaft misalignment causing premature failure.

• The structure consists of two rows of balls, which help distribute the load evenly and increase the bearing's operational efficiency.

5. Design:

• The self-aligning design features a spherical outer race, allowing the bearing to adjust to misalignments or shaft deflections. This design feature makes the bearing suitable for applications where alignment cannot always be perfectly maintained, such as in motors, generators, and agricultural machinery.

6. Lubrication:

• Typically lubricated with grease or oil, ensuring smooth operation and reduced friction. The lubrication helps to extend the bearing’s service life and improve its overall performance in demanding applications.

7. Applications:

• Commonly used in electric motors, pumps, conveyors, compressors, automotive components, and other machinery where misalignment, vibration, or thermal expansion may occur.

• Its ability to handle misalignment without causing excessive wear or noise makes it a popular choice for various industrial, automotive, and agricultural machinery.

8. Operating Temperature Range:

• Depending on the lubricant and materials used, the operating temperature range typically extends from -30°C to +120°C, with special variants designed for higher or lower temperatures if needed.

In summary, the 13944 Automatic Self-Aligning Ball Bearing is an essential component in systems where misalignment tolerance, durability, and high load handling are critical factors. Its robust design ensures long-term reliability even in challenging operational environments.
