A compact, powerful solution where metal bearings can’t perform.
🔍 Comparison Table: 4x10mm Full Ceramic vs. 4x10mm Chrome Steel Bearing
| Feature | Full Ceramic (ZrO₂) | Chrome Steel |
|---|---|---|
| Material | Zirconia ceramic | 52100 chrome steel |
| Corrosion Resistance | Excellent | Poor to moderate |
| Weight | Lighter | Heavier |
| Magnetism | Non-magnetic | Magnetic |
| Cleanroom Safe | Yes | No |
| Price | Higher | Lower |
Built to excel in precision environments where standard bearings can't handle moisture, chemicals, or magnetic interference.
Got these hoping to stop worrying about saltwater corrosion and was blown away with how fast and maintenance free they are. They are a bit noisier and slightly more gritty than oiled steel bearings but if you’re using them in salt water it is 100% worth it. I have been using them every day for over a month and have had 0 issues. Hoping they last many more months.
