Customer Questions

How do self-aligning ball bearings differ from spherical (self-aligning) roller bearings?

Self-aligning ball bearings suit light loads with high-speed rotation, while spherical roller bearings suit heavy loads with low-speed rotation.

What greases are recommended for self-aligning ball bearings?

The recommended grease for self-aligning ball bearings depends on usage conditions.

You can use the selection criteria for finding suitable grease for deep groove ball bearings with self-aligning ball bearings as well.

Can I use self-aligning ball bearings with thrust loads?

Because they have small contact angles, self-aligning ball bearings have extremely limited capacity for thrust loads.

Please consider using thrust bearings with aligning seats if thrust loads are expected.
