Deep Groove Ball Bearing 6304 Zz 2RS 20x52x15mm P0-P4 Precision for Industrial Machinery

Minimize Downtime with Reliable Deep Groove Ball Bearing 6304 for Industrial Machinery

Industrial machinery operators know the frustration of unexpected downtime caused by bearing failures. A seized 6304 bearing in a production line can halt operations for hours, eroding profits and delaying orders. Many face challenges with inconsistent quality from low-cost suppliers, where bearings fail prematurely due to poor materials or imprecise manufacturing. Sourcing standard bearings with flexible MOQs and fast delivery often feels like an impossible balance between cost and reliability.

Precision-Engineered 6304 Bearing for Consistent Performance

Our Deep Groove Ball Bearing 6304 is designed to address these pain points head-on. With dimensions 20×52×15mm and precision ratings from P0 to P4, it meets the strict requirements of industrial machinery, ensuring smooth operation and extended service life. As an integrated manufacturer with full R&D and QC labs, we control every production step—from raw material selection to final inspection. Whether you need a single unit for emergency replacement or bulk orders for production lines, our 1pc MOQ and 5–15 day bulk delivery ensure you get the bearings you need when you need them.

Optimal Performance in Diverse Industrial Conditions

This 6304 bearing excels in radial load applications, making it ideal for high-speed rotating components in machine tools, conveyors, and electric motors. The single-row design with a 0° contact angle ensures efficient load distribution, while vibration grades Z1V1 to Z3V3 accommodate varying noise requirements—critical for precision equipment like printing presses. Available with Zz (metal shielded) or 2RS (rubber sealed) options, it provides reliable protection against contaminants, extending service life in dusty or humid industrial environments.

Características técnicas que impulsan la eficiencia de la maquinaria

The performance of your equipment depends on key bearing specifications. Our 6304 bearing’s precision rating directly impacts operational accuracy: P4 grade minimizes runout for CNC machine spindles, while P0 offers cost-effective reliability for general industrial use. Vibration levels (Z1V1 to Z3V3) reduce noise and energy consumption—essential for meeting workplace standards and optimizing machine efficiency. The choice between Zz and 2RS seals balances maintenance needs: Zz shields allow for relubrication, while 2RS seals provide superior protection in wet or dirty conditions. Made from high-grade bearing steel, this component delivers consistent hardness and wear resistance, even under continuous operation.
