Direct G5 Grade Silicon Nitride Ball – 1/4 Inch (6mm/6.35mm) – Precision Ceramic Bearing Component
Ultra-high-purity G5-grade Si3N4 ceramic ensures exceptional hardness (HV10 ≥ 1500) and wear resistance. Precision-polished to ≤0.1μm surface roughness for ultra-smooth rotation in high-speed bearings. Thermal stability maintains performance from -60°C to 800°C, ideal for aerospace and automotive turbochargers. Corrosion-proof material excels in chemical processing, marine, and medical implant applications. Near-perfect sphericity (±0.001mm) minimizes vibration in CNC machinery and high-end bicycle hubs. Non-magnetic and electrically insulating for semiconductor manufacturing and MRI equipment. Available in dual sizing (6.00mm exact / 6.35mm imperial) for global engineering specifications. Direct factory pricing – bulk orders receive additional wholesale discounts with guaranteed quality.
