Self-aligning ball bearings are high-performance engineered components featuring two raceways in the inner ring and a common sphered raceway in the outer ring. This unique architectural design grants the bearing an inherent self-alignment property, allowing it to accommodate angular misalignment within a range of 1.5° to 3°, making them indispensable for applications where mounting errors or shaft deflections are prevalent.
Designed primarily to carry radial loads, these bearings also possess the capability to handle a certain amount of axial loads. Despite a relatively lower loading capacity compared to roller variants, they are optimized for high-speed rotation. For installations on smooth shafts without shoulders, our 1000k series with tapered bores (1:12) and adapter sleeves provides a precise, secure position fixing and simplified mounting and dismounting processes.

Frequently Asked Questions
The primary advantage is their ability to accommodate angular misalignment between the shaft and the housing, which prevents premature wear and failure caused by shaft deflection or mounting errors.
Yes, while they are primarily designed for radial loads, self-aligning ball bearings can support a moderate amount of axial loads in both directions.
A tapered bore allows the bearing to be mounted on a tapered shaft or used with an adapter sleeve, which is ideal for shafts without shoulders and enables easier mounting/dismounting.
They are widely used in general machinery, agricultural equipment, conveyors, and any rotating equipment where perfect shaft alignment is difficult to maintain.
Depending on the operating speed and environment, they can be lubricated with high-quality industrial grease or circulating oil to ensure minimal friction.
These bearings typically permit an angular misalignment range between 1.5° and 3°, effectively absorbing errors in mounting or shaft deflection.
