F6709 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The F6709 flange miniature bearing is a high-precision integral flanged deep groove ball bearing designed for compact micro machinery and high-speed precision rotary automation systems. Featuring a one-piece flange positioning structure and ultra-fine polished raceways, this bearing delivers outstanding dimensional stability, ultra-low noise and vibration, and consistent high-speed rotation performance. The integrated flange structure simplifies installation, ensures accurate axial positioning, and effectively prevents shaft displacement during long-duration cyclic operation. Available in three standard industrial versions, including F6709 open type, F6709ZZ double metal shield type and F6709-2RS double rubber sealed type, it suits dry, dusty, humid and moderately harsh working conditions. Offered in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6709 meets diverse industrial demands for economical, sanitary, wear-resistant and anti-corrosion precision applications.
F6709 Open / ZZ / 2RS Structural Features
F6709 Open Type: The open non-sealed structure maximizes air circulation and heat dissipation, effectively avoiding thermal fatigue and precision loss during continuous high-speed operation. It allows easy grease refilling and simple routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor environments and fully enclosed precision micro equipment, it maintains stable accuracy and long-cycle operational consistency.
F6709ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6709ZZ effectively blocks fine dust, dry particles and floating industrial debris. The non-contact design retains original smooth rotation and high-speed precision with minimal friction loss. With excellent durability and cost performance, this model is widely used for dry workshop environments and long-running micro high-speed mechanical systems.
F6709-2RS Double Rubber Seals: The fully sealed 2RS structure adopts double-sided contact rubber seals to isolate moisture, splash water, oil mist and corrosive dust. It locks internal lubricant firmly to prevent leakage and aging, enabling long-term maintenance-free operation. This highly adaptable bearing performs reliably in humid, dusty and complex indoor and outdoor working scenarios.
F6709 Bearing Material Performance
Carbon Steel: Cost-effective industrial-grade material with uniform hardness and stable anti-fatigue performance. Carbon steel F6709 bearings deliver reliable wear resistance and smooth high-speed rotation for standard precision micro machinery, ideal for mass production and budget-friendly automation projects.
304 Stainless Steel: Food-grade stainless steel with excellent rust and oxidation resistance. It prevents surface corrosion in humid and open environments, making it suitable for medical devices, food processing machinery and sanitary-grade precision equipment.
316 Stainless Steel: Marine-grade anti-corrosion stainless steel with strong resistance to salt spray, acid and alkali erosion. It maintains stable precision in coastal humidity and light chemical environments for marine instruments and chemical miniature machinery.
420 Stainless Steel: High-toughness martensitic stainless steel with balanced corrosion resistance and high surface hardness. It provides stable wear resistance and dimensional stability during long-term high-frequency cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance and structural stability. It withstands heavy friction and weak corrosive conditions, sustaining precise and stable rotation for high-end micro precision systems.
