💡 What is an angular contact ball bearing used for?

Angular contact bearings are handy for precision, high-load rotary applications where both radial and axial forces occur.

• Transfers axial and radial loads in one direction
• Common in spindles, tool changers, and gear drives
• 40° contact angle provides strong axial support
• Ideal for CNC machines, robotics, and packaging equipment
