💡 Why use angular contact bearings in pairs?
Single-row angular contact bearings handle axial loads in one direction, so they’re often mounted in matched pairs - back-to-back (DB), face-to-face (DF), or tandem (DT) - to support axial loads from both directions and improve stability under radial forces.

Built for speed, load precision, and long-lasting performance in demanding rotational systems.
