F6703 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The F6703 flange miniature bearing is a high-precision integrated flanged deep groove ball bearing designed for compact, space-limited micro mechanical systems. Combining a one-piece flange positioning structure and high-precision rolling elements, this bearing delivers low vibration, ultra-smooth high-speed rotation and excellent dimensional stability. It simplifies installation, ensures accurate axial positioning and effectively prevents shaft displacement during continuous operation. Available in three mainstream industrial versions including open type, F6703ZZ double metal shield type and F6703-2RS double rubber sealed type, it adapts to dry, dusty and humid working conditions. Supported by five industrial-grade materials, carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6703 meets economical, sanitary, high-wear and anti-corrosion industrial application requirements.
F6703 Open / ZZ / 2RS Structural Features
F6703 Open Type: The unsealed open structure provides unobstructed airflow and superior heat dissipation, avoiding thermal accumulation during long-duration high-speed operation. It allows convenient grease refilling and straightforward routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor environments and fully enclosed precision micro machinery, it maintains ultra-high running accuracy and stable long-cycle performance.
F6703ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6703ZZ effectively blocks dry fine dust and floating micro debris. The non-contact protective design preserves original high-speed smoothness with negligible friction loss. Featuring stable durability and excellent cost performance, it is the optimal choice for dry industrial environments and long-term continuous micro high-speed operation.
F6703-2RS Double Rubber Seals: The fully sealed F6703-2RS adopts double-sided contact rubber seals to isolate moisture, water splashes, oil mist and corrosive dust. It tightly locks internal lubricant to prevent leakage and aging, realizing long-term maintenance-free operation. This versatile sealed model runs stably in humid, dusty and mildly harsh outdoor and workshop environments.
F6703 Bearing Material Performance
Carbon Steel: High cost-performance industrial material with uniform hardness and stable anti-fatigue properties. It provides reliable wear resistance and smooth high-speed rotation for standard micro precision equipment, perfectly suitable for mass production and cost-sensitive industrial projects.
304 Stainless Steel: Food-grade stainless steel with outstanding rust and oxidation resistance. It resists micro corrosion in humid and open environments, ideal for food processing accessories, medical devices and sanitary-grade precision machinery.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong tolerance to salt spray, acid and alkali erosion. It maintains stable precision in coastal high-humidity and light chemical environments, applicable for marine micro instruments and chemical miniature equipment.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It delivers stable wear resistance and dimensional stability during frequent high-speed cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with premium abrasion resistance. It withstands severe wear and weak corrosive conditions, ensuring long-term accurate and stable rotation for high-end micro precision systems.
Core Advantages And Industrial Applications
The F6703 flange miniature bearing features an integrated flange positioning design, compact lightweight structure, ultra-low noise and durable high-speed precision.
