Customer Questions

How do I lubricate spherical roller bearings? Are oil grooves and oil holes provided?

Yes, oil grooves and oil holes come standard in the outer ring of NSK spherical roller bearings for easy lubrication. These are indicated by “E4” in the designation.

How is using two tapered roller bearings different from using a spherical roller bearing?

Assuming that a face-to-face combination (DF arrangement) with the same roller arrangement is used, the biggest differences are the amount of permissible misalignment and the spherical roller bearing's capacity for self-alignment.

What grease is recommended for spherical roller bearings?

We generally recommend Shell Alvania S2 grease (AS2) for spherical roller bearings.
