💡 What’s the benefit of using an angular contact ball bearing with a 40° contact angle?
They’re great for combined load handling and rigid axial alignment:
-
Support both radial and high axial loads in one direction
-
Great for high-speed shafts and rotating assemblies
-
Allow preload adjustment for enhanced rigidity
-
Used in pairs or sets for precise load direction control
Built to spin fast and support both thrust and radial forces, this bearing’s made for serious machinery. Add it to your lineup and keep your system dialed in!
