Self Aligning Ball Bearings

What Are Self-Aligning Bearings Used For?

Self-aligning bearings are used in applications where shaft misalignment is a concern, providing reliable operation even when the shaft and housing are not perfectly aligned. Commonly found in industries such as automotive, agriculture, and industrial machinery, these bearings excel in environments with fluctuating loads and potential misalignment.

They are ideal for electric motors, conveyor systems, and other equipment where precise alignment is difficult to maintain, ensuring smooth operation and reducing the risk of premature bearing failure. Their ability to tolerate angular deviations makes them indispensable in various dynamic and heavy-duty applications.

How Do Self-Aligning Bearings Work?

Self-aligning bearings operate by using two rows of balls that sit in a spherical raceway within the outer ring. This unique design allows the bearing to adjust to angular misalignments between the shaft and housing. As the shaft moves, the inner ring and balls shift slightly to maintain contact and reduce stress, ensuring smooth operation even if the shaft is not perfectly aligned.

This self-adjustment capability is crucial in applications where precision alignment is difficult or where external forces may cause shaft deflections. By accommodating these misalignments, self-aligning bearings reduce the likelihood of premature wear and tear, leading to longer bearing life and more consistent performance. Additionally, they help minimise vibration and noise, further enhancing the efficiency and reliability of the machinery in which they are used.

Types of Self-Aligning Bearings

Self-aligning bearings come in several types, each designed to address specific needs and applications:

Self-Aligning Ball Bearings: These bearings have two rows of balls with a common spherical raceway in the outer ring. They are ideal for applications requiring high tolerance to misalignment and low friction.

Self-Aligning Roller Bearings: These bearings are similar in design to ball bearings but have cylindrical bore or tapered rollers instead of balls. They can handle higher loads and are suitable for more demanding applications.

Double Row Self-Aligning Bearings: These bearings have two rows of balls, providing greater load-carrying capacity and enhanced stability while maintaining self-aligning properties.

Sealed Self-Aligning Bearings: These bearings come with integrated seals to protect against contaminants and retain lubrication, making them ideal for environments where cleanliness and maintenance are concerned.

Open Self-Aligning Bearings: Open bearings do not have seals, allowing for easier inspection and lubrication, which is beneficial in applications where regular maintenance is performed.

Each type offers specific benefits depending on the operational environment, load requirements, and desired maintenance levels. Looking for any of our other stock? We also provide a range of other bearing options, including taper roller bearings, angular ball bearings, and more.
