6304 N Bearing Product Overview & Core Advantages
The 6304 N is a single row deep groove ball bearing designed for superior radial load capacity and high-speed operation. As a metric precision bearing with P6 tolerance class, it delivers exceptional running accuracy and rotational stability. Its key advantage lies in the snap ring groove on the outer ring, which simplifies axial positioning and reduces housing design complexity and costs. This open-type construction, combined with high-grade chrome steel components, ensures reliable performance in demanding applications.

6304 N Bearing Structural Features & Performance Benefits
Optimized Deep Groove Design: The continuous raceway geometry enables smooth operation under high radial loads (3777 lbf dynamic rating) while accommodating moderate axial loads in both directions.
Precision Engineering: Manufactured to P6 tolerance class with CN radial clearance, ensuring minimal vibration and precise shaft guidance for high-speed applications up to 19,000 rpm.
Snap Ring Groove Advantage: The outer ring groove accepts snap rings for simplified axial location, reducing housing machining requirements and assembly time while maintaining precise bearing positioning.
Premium Material Construction: Chrome steel rings and balls combined with stainless steel cage provide excellent durability, corrosion resistance, and consistent performance across the operating temperature range (-30° to 120°C).
