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 available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing , which can be caused, for example, by shaft deflection.

A special bore tolerance allows easy mounting and dismounting.
A self-aligning ball bearing is a type of rolling-element bearing designed to manage radial loads and small axial loads in both directions. They are known for their ability to self-align, which means they can compensate for misalignment caused by mounting errors, shaft deflection, or other factors. This feature makes them suitable for applications where alignment is a challenge.
Self-aligning ball bearings typically have two rows of balls, a common sphered raceway in the outer ring, and two deep uninterrupted raceway grooves in the inner ring. The bearings are available with an extended inner ring, which is used in applications employing commercial ground shafting. This design enables easy mounting and dismounting due to a special bore tolerance.
To find the appropriate self-aligning ball bearing for your application, you can refer to bearing charts provided by manufacturers. These charts usually include information such as bearing dimensions, load ratings, speed limits, and other relevant specifications. By comparing your application requirements with the specifications provided in the chart, you can select the most suitable self-aligning ball bearing.
When searching for a self-aligning ball bearing chart, you can look for resources from well-known bearing manufacturers such as viiplus. Weoften provide product catalogs, technical data sheets, and selection guides to help you find the right bearing for your needs.

Self-aligning ball bearings for the textile industry
Self-aligning ball bearings are an excellent choice for the textile industry due to their ability to accommodate misalignment, handle moderate radial loads, and tolerate small axial loads. Textile machinery often operates at high speeds and may experience shaft misalignment due to various factors such as mounting errors or shaft deflection. Self-aligning ball bearings can address these challenges and contribute to the smooth operation of textile equipment.
Some key features of self-aligning ball bearings that make them suitable for textile industry applications include:
-
Self-aligning capability: These bearings can accommodate angular misalignments up to approximately 3 degrees, which helps to minimize stress on the bearing and reduce wear.
-
Low friction: Self-aligning ball bearings have a low friction coefficient, which enables textile machinery to operate at high speeds with reduced energy consumption and heat generation.
-
Easy installation and maintenance: The bearings can be easily mounted and dismounted, which simplifies maintenance and reduces downtime.
-
Sealing options: Self-aligning ball bearings can be equipped with various sealing options to protect against contamination, such as dust and fibers commonly found in textile environments. Proper sealing helps to extend the service life of the bearing.
To find self-aligning ball bearings suitable for textile industry applications, you can consult bearing catalogs, technical data sheets, and selection guides provided by us.
When selecting a self-aligning ball bearing for textile industry applications, consider factors such as the bearing’s load-carrying capacity, operating temperature range, and sealing requirements to ensure it meets your application’s specific needs.
