Precision bearings Self-Aligning Ball Bearing 13940

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

Introduction to the Self-aligning Ball Bearing 13940

The self-aligning ball bearing, model number 13940, is a specialized type of bearing designed to accommodate misalignment between the inner and outer rings. This feature makes it especially useful in applications where shafts may be subjected to angular misalignment or where the bearing housing might not be perfectly aligned with the shaft. The 13940 self-aligning ball bearing combines the advantages of both a deep groove ball bearing and a spherical bearing, making it a versatile and reliable solution for a wide range of mechanical systems.

Key Features and Design

1. Structure: The 13940 self-aligning ball bearing consists of two rows of balls, which are situated between an inner race and an outer race. The outer race is shaped in a spherical form, allowing for a certain degree of alignment compensation between the two races. This structure enables the bearing to tolerate misalignment, reducing wear and tear that would otherwise occur due to shaft deflection or housing irregularities.

2. Self-aligning Capability: The most significant feature of the self-aligning ball bearing is its ability to adjust to misalignment. This misalignment can be caused by slight deformation of the housing or shaft, and the spherical shape of the outer race allows the bearing to realign itself, ensuring smooth rotation and minimizing stress on the components.

3. Applications: The 13940 self-aligning ball bearing is commonly used in applications where precision and smooth operation are essential, even when there are slight misalignments in the mounting. These include electric motors, pumps, conveyors, agricultural machinery, and various types of industrial equipment. It is particularly valuable in situations where alignment errors are likely due to mechanical stress or manufacturing tolerances.

4. Load Capacity: The bearing is capable of handling both radial and axial loads. However, it is designed to perform optimally under radial loads. The design of the self-aligning ball bearing minimizes friction and enhances the bearing’s ability to carry loads, ensuring longer service life and less frequent maintenance.

5. Material and Durability: Self-aligning ball bearings like the 13940 are typically made from high-grade steel, which offers excellent durability, resistance to wear, and the ability to perform under high loads and at varying speeds. For specific applications, these bearings can also be made from stainless steel or ceramic materials to improve corrosion resistance and performance in harsher environments.

Benefits

• Reduced Risk of Damage: The self-aligning feature helps reduce the risk of premature bearing failure due to misalignment, as it can compensate for angular errors that would otherwise cause increased wear.

• Longer Service Life: The ability to realign itself reduces the operational stress on the bearing, leading to a longer service life.

• Versatility: The 13940 bearing is suitable for a wide range of industrial applications where alignment is not always perfect.
