PRECISION BALL
MetalBall is a french manufacturer of high precision ceramic balls (silicon nitride ball -Si3N4 ball) for ball bearing and ball screw. Our manufacturing process can obtain a higher surface quality than the current standard. In addition to our visual inspection, we can perform a fluorescent penetrant inspection (certified NADCAP) to guarantee the absence of “C-crack”.
We are also able to supply aluminium oxide (Al2O3) and zirconium oxide (ZrO2) balls.
| Material | Ceramic grade | Density (Kg/dm3) | Hardness |
| Ceramic balls | Silicon Nitride Si3N4 balls – Class I ASTM F2094 | 3,26 | 1400-1600 HV |
| Alumina Oxide – Al2O3 balls | 3,90 | 1250 -1700 HV | |
| Zirconium Oxide -ZrO2 balls | 6,00 | 1200 HV | |
| Silicon Carbide -SiC balls | 3,15 | 2200-2800 HV |
For industrial applications we can supply the balls via our Supply Chain. In all cases, each batch is validated by our certified quality system based on aeronautical requirements.
