Precision Silicon Nitride Ceramic Balls for Dental Handpieces
High-performance 1.588mm (1/16") diameter balls with ultra-smooth 11.906mm (15/32") finish for unmatched durability and friction reduction. Medical-grade silicon nitride (Si3N4) material ensures biocompatibility, corrosion resistance, and extreme thermal stability (up to 1,400°C). Ideal for high-speed dental handpieces, bearings, and precision instruments requiring zero lubrication and minimal wear. Laser-polished surface (Ra <0.02μm) guarantees silent operation and extended lifespan in sterilization-heavy environments. Global wholesale pricing with bulk discounts—direct factory supply eliminates middleman markups.
