This 10-pack of 3.5mm loose ceramic balls is made from tough, lightweight Si3N4 (Silicon Nitride). Whether you're rebuilding a bearing set, upgrading a bicycle hub, or using them in a precision mechanism, these G5-grade balls deliver high-speed, low-friction performance with excellent wear resistance.

✅ Size: 3.5mm diameter
✅ Quantity: 10 balls
✅ Material: Si3N4 Ceramic (Silicon Nitride)
✅ Grade: G5 precision
✅ Color: Dark gray (typical for Si3N4)
✅ Use: Loose replacement balls for bearings and custom setups

💡 What makes ceramic balls better than steel in high-speed use?
Because ceramic balls like Si3N4 are:

1. 60% lighter - less centrifugal force = less wear

2. Non-corrosive and non-conductive - perfect for wet or electric environments

3. Smoother and harder - which reduces rolling friction and extends life

Stock up on these and roll smoother, longer, and cooler.
