💡 What is the G40 grade on bearing balls and why does it matter?
Grade numbers define the roundness and precision of the ball.

• Lower numbers = higher precision (G40 is good general-purpose)

• Ensures even load distribution in bearing races

• Reduces friction and vibration in moving parts

• Great for replacement parts or DIY builds
