What is a self-aligning ball bearing?

It is a double-row ball bearing with a spherical outer ring raceway. It has low axial load capacity and is not suitable for high-speed rotation. However, it is used as a relatively inexpensive bearing with self-aligning capability.

How should self-aligning ball bearings and self-aligning roller bearings be used differently?

Self-aligning roller bearings are suitable for heavy loads and low-speed rotation, while self-aligning ball bearings are suitable for light loads and high-speed rotation.

What is the recommended grease for self-aligning ball bearings?

The recommended grease for self-aligning ball bearings varies depending on the operating conditions. Grease selection should follow the same criteria as for deep groove ball bearings, choosing grease that suits the operating conditions.

What is an advantage of Tapered bore type?

Self-aligning ball bearings with tapered bores are typically mounted using an adapter sleeve or withdrawal sleeve. This setup facilitates easy mounting and dismounting on the shaft, which can be particularly beneficial in applications requiring frequent bearing maintenance or replacement.
