MODEL 6003-ZZ IN DIAMETER (BORE) 17 mm TYPE Metal Shield on Both Sides OUT. DIAMETER 35 mm MATERIAL 100% Chrome Steel (AISI 52100) RPM 21,000 WIDTH (THICKNESS) 10 mm CLEARANCE C3 (Pre-Lubricated) DYNAMIC LOAD 1,550 lbs STATIC LOAD 770 lbs Read More 6003-ZZ Ball Bearing The 6003-ZZ Ball Bearing is a deep groove ball bearing engineered for applications requiring fast rotational response, low mechanical friction, and efficient performance in compact high-speed equipment. Its double metal shield (ZZ) configuration supports lower rolling resistance compared to rubber-sealed models, making this bearing widely used in electric motors, industrial ventilation systems, and automated equipment operating continuously at elevated RPM. Manufactured from chrome steel and supplied factory pre-lubricated, the 6003-ZZ combines smooth rotation, reduced vibration, and dependable operational stability in light and medium industrial applications. Common Applications for the 6003-ZZ The 6003-ZZ is frequently used in systems prioritizing operating speed and mechanical efficiency, including: Compact electric motors Industrial fans HVAC equipment Power tools Automated machinery Small rotating pumps Material handling equipment Continuous ventilation systems The 6000 series is widely used in compact industrial applications due to its combination of low friction, versatility, and continuous-duty performance. Features That Make the 6003-ZZ Stand Out Metal shields for reduced rolling resistance Metal shields help minimize operational friction and support medium and high-speed applications. Excellent high-speed performance The 6003-ZZ is designed for elevated RPM applications with stable operation and reduced heat generation. Smooth and quiet operation Deep groove geometry contributes to reduced vibration and more consistent rotation in motors and electromechanical equipment. Strong energy efficiency Lower rolling resistance helps improve mechanical efficiency in continuous rotating equipment. Chrome steel construction Manufactured from hardened chrome steel to provide dependable mechanical strength and long operational durability in industrial applications. When Is the 6003-ZZ the Best Choice? This model is commonly selected when applications require: high rotational speed reduced operational friction continuous-duty performance compact equipment low vibration levels 6003-ZZ vs 6003-2RS Although both are deep groove ball bearings, the models are optimized for different priorities. 6003-ZZ metal shields lower rolling resistance improved high-RPM response better suited for dry environments 6003-2RS rubber seals improved grease retention additional protection against fine particles focused on reduced maintenance Installation Recommendations To improve bearing service life: Use proper installation tools Avoid installation impact Verify shaft alignment Control operating temperature Monitor unusual operating noise PGN Bearings Product Line PGN Bearings supplies components for mechanical power transmission, industrial automation, and rotating systems. The catalog includes deep groove ball bearings, mounted bearings, pillow blocks, roller chains, flanged bearings, and solutions engineered for continuous industrial applications.
