💡 Why are open double row angular contact bearings used for combined axial and radial loads?
Open angular contact bearings are designed to share thrust and radial forces efficiently in demanding setups.

• Contact angles allow controlled axial load handling in both directions

• Double row layout improves stiffness and load balance

• Open design works well with oil systems and custom lubrication plans

Use this bearing when your application needs solid load control, higher speed capability, and smooth performance without sealing drag.
