💡 What does G10 grade mean for loose bearing balls?
It refers to the surface precision and roundness tolerance used in high-quality rolling elements.
- Tighter tolerance means smoother rolling contact
- High chrome content boosts hardness and wear life
- Ideal for restoring bearing performance without replacing the whole assembly

If you’re rebuilding a hub or refurbishing a bearing race, these precision balls are a clean upgrade, grab a pack and keep your parts running smooth again.
