6702 Bearing Product Overview & Core Advantages
The 6702 metric ball bearing is a precision-engineered single row deep groove ball bearing designed for reliable performance in compact spaces. Characterized by its open design and ABEC-1 precision class, this bearing delivers excellent radial load capacity and smooth operation. Its minimal cross-section (4 mm width) and lightweight construction (3.6 g) make it ideal for applications where space and weight are critical constraints while maintaining robust performance.

| Open | No seals or shields - allows for custom lubrication |
6702 Bearing Structural Features & Performance Benefits
Compact Design & High Precision: The single row deep groove construction with ABEC-1 tolerance class ensures smooth operation and precise rotational accuracy. The C0 radial internal clearance (0.003mm to 0.018mm) provides optimal performance for most standard applications.
Superior Material Construction: Manufactured with chrome steel rings and balls combined with a stainless steel cage, this bearing offers excellent durability and corrosion resistance. The material combination ensures reliable operation across a wide temperature range (-30°C to 110°C).
Load Capacity & Speed Performance: With a radial dynamic load rating of 211 lbf and static load rating of 131 lbf, this bearing handles significant radial loads despite its compact size. The limiting speed of 13,000 rpm makes it suitable for high-speed applications when properly lubricated.
