Reduce Vehicle Downtime with Reliable 6304 Deep Groove Ball Bearings

Transportation vehicles depend on bearings that perform under constant radial loads and varying speeds. A failed bearing can halt operations, delay deliveries, and increase maintenance costs. Many operators struggle with inconsistent quality from unknown suppliers, leading to premature wear and unexpected breakdowns. The 6304 deep groove ball bearing addresses these challenges with precision engineering and durable materials.

Precision Engineered for Transportation Applications

Our 6304 deep groove ball bearing, sized 20x52x12mm, is designed to meet the rigorous demands of transportation vehicles. As a professional bearing manufacturer with over 18 years of experience, we produce this bearing to P0-P4 precision grades and Z2-Z4 noise levels, ensuring smooth operation even in high-vibration environments. The radial bearing structure supports heavy loads while maintaining low friction, making it ideal for wheel hubs, transmission systems, and conveyor mechanisms in commercial and industrial vehicles.

Built to Withstand Transportation Workloads

This 6304r radial bearing excels in applications requiring reliable performance under continuous use. Its single-row design and 0° contact angle optimize radial load capacity, critical for supporting vehicle weight and dynamic forces during acceleration and braking. The bearing steel construction ensures resistance to wear and fatigue, extending service life in harsh conditions such as dust, moisture, and temperature fluctuations common in transportation and logistics operations.

Technical Features That Ensure Performance

The 20x52x12mm deep groove ball bearing integrates key features that enhance its functionality. The bearing steel material provides high hardness and toughness, essential for withstanding the stresses of transportation equipment. Its precision manufacturing ensures tight dimensional tolerances, reducing vibration and noise during operation. Available with ZZ, 2RS, or DDU seals, the bearing offers options for contamination protection, extending maintenance intervals and improving reliability in diverse working environments. The single-row configuration balances load capacity and compact design, fitting seamlessly into standard transportation vehicle assemblies.

Why Quality Matters More Than Price for Transportation Bearings

Choosing a low-quality 6304 bearing for transportation vehicles can lead to significant hidden costs. Inferior materials and imprecise manufacturing result in early failure, causing vehicle downtime, expensive repairs, and potential safety risks. Our bearings meet ISO, ABMA, and DIN international standards, ensuring consistent performance and reliability. With a 12-month warranty and strict quality control processes—including incoming material inspection and full-process production supervision—we deliver bearings that reduce total cost of ownership by minimizing replacements and maintenance.
