Customer Questions

What are radial loads and axial loads?

Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.

How do deep groove ball bearings (DGBBs) differ from single-row angular contact ball bearings?

While DGBBs can handle axial loads in both directions, single-row angular contact ball bearings can only receive axial load in one direction.

What are the differences between open, sealed, and shielded deep groove ball bearings?

Seals and shields offer additional protection for bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings, then finally open bearings.
NSK uses supplementary designations D, DU, DW, and V (DD, DDU, DDW, VV) for sealed bearings and Z (ZZ) for shielded bearings. No supplementary designations are listed for open bearings.
