💡 Why are double row angular contact ball bearings used instead of single row designs?
Double row angular contact bearings are used when compact assemblies need to support loads from multiple directions.

• Two rows allow the bearing to handle axial loads in both directions

• Back to back internal geometry improves rigidity and moment load capacity

• Single bearing design saves space compared to matched bearing pairs

This Nachi bearing is a handy choice when you want compact load handling, stable axial support, and dependable performance in industrial and mechanical applications.
