Self Aligning Ball Bearings

About

Self Aligning Ball Bearings at Bearing King At Bearing King, we offer a comprehensive collection of self aligning ball bearings suitable for a wide range of industrial and mechanical applications. These specialised bearings are uniquely designed to accommodate misalignment between the shaft and housing, making them ideal for use in situations where mounting errors or shaft deflections may occur. What Are Self Aligning Ball Bearings? Self aligning ball bearings consist of an inner ring with two raceways and an outer ring with a single spherical raceway. This design enables the bearing to tolerate angular misalignment of the shaft relative to the housing without impacting performance or longevity. The self-aligning feature makes them particularly useful in applications where shaft bending or misalignment is unavoidable. There are two primary bore designs available: Cylindrical bore : Commonly used in standard applications for ease of installation. Tapered bore : Available within certain size ranges, ideal for applications requiring a secure fit on a tapered shaft or adapter sleeve. Sealed Self Aligning Ball Bearings For added protection and longevity, self aligning ball bearings are also available in a sealed version , featuring contact seals on both sides. These seals are constructed from acrylonitrile-butadiene rubber (NBR), reinforced with sheet steel for enhanced durability. This material is oil- and wear-resistant, ensuring a reliable seal in challenging environments. The operating temperature range for these sealed bearings is –40°C to +100°C, with tolerance for brief periods up to +120°C. The seal lips lightly contact a smooth chamfer on the inner ring, providing an effective seal with minimal friction. These sealed self aligning bearings are lubricated for life and require no additional maintenance—perfect for users looking for a reliable, low-maintenance solution. Note: Sealed bearings should not be heated above 80°C prior to mounting and are not intended to
