High-Precision R144 Ball Bearing for Dental Handpieces
Ultra-smooth operation with 3.175×6.35×2.38mm compact design, engineered for high-speed dental tools. Made from premium chrome steel for exceptional durability and corrosion resistance. Precision-ground raceways reduce friction, ensuring quiet performance under continuous use.
Ideal for dental drills, engravers, and rotary tools requiring reliability at 30,000+ RPM. Hardened steel balls and shielded design prevent debris ingress, extending lifespan. OE-compatible replacement for SR144 models with tighter tolerances than generic bearings.
Direct-from-factory pricing with bulk discounts for clinics and distributors. Stocked in OEM packaging with full dimensional certification. Ships globally with same-day dispatch on wholesale orders.
