F6702 Bearing Product Overview & Core Advantages
The F6702 is a metric miniature flanged ball bearing designed for compact applications requiring reliable radial load support. Its single-row construction and open seal type facilitate easy re-lubrication, while the integral flange provides secure axial location and simplifies housing design. Manufactured to ABEC-1 precision tolerance class, this bearing delivers consistent performance in high-speed applications, with a limiting speed of 11,000 rpm. The use of chrome steel rings and stainless steel cage ensures durability and corrosion resistance, making it ideal for precision instruments and small machinery.

F6702 Bearing Structural Features & Performance Benefits
Compact Design & Space Optimization: With a minimal cross-section (4mm width) and integrated flange, the F6702 enables space-saving designs while providing secure mounting. The flange outer diameter of 22mm offers stable mounting surface for precise axial location.
High-Speed Capability: The stainless steel cage and optimized ball complement (14 balls) ensure stable operation at high rotational speeds up to 11,000 rpm. The open design reduces friction and heat generation during high-speed applications.
Precision Performance: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (C0: 0.002mm to 0.013mm), this bearing delivers consistent running accuracy and minimal vibration. The chrome steel construction provides excellent wear resistance and dimensional stability.
Versatile Load Capacity: With a dynamic load rating of 211 lbf and static load rating of 131 lbf, the F6702 handles significant radial loads despite its miniature size. The optimized ball diameter of 1.588mm ensures efficient load distribution.
