Ultra-Durable 6306 ZZ Ball Bearing – Precision Engineered for Smooth Performance
High-quality chrome steel construction ensures exceptional wear resistance and extended service life. Deep groove design minimizes friction, reducing operational noise for quieter machinery. Precision-machined with tight tolerances (30x72x19mm) for seamless rotation in high-speed applications. Dual metal shields (ZZ) provide superior dust protection without compromising lubrication efficiency. Ideal for electric motors, industrial gearboxes, automotive components, and HVAC systems. Heat-treated raceways and polished balls enhance load capacity (dynamic: 22kN, static: 15kN). Cost-effective bulk solution for manufacturers – wholesale pricing without compromising ISO-certified quality. Direct global shipping available for OEMs and distributors.
Key Advantage:
Lowest friction coefficient in its class (0.0015) – outperforms standard 6306-2RS variants in high-RPM scenarios.
