F6909 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Thin Section Bearing
The F6909 flange deep groove ball bearing is a high-performance thin-section precision bearing developed for ultra-compact, space-limited mechanical systems requiring larger bore dimensions, improved radial load capacity and consistent long-term high-speed rotary stability. Featuring a thickened integrated flange and premium finely polished deep groove raceways, this bearing delivers excellent structural rigidity, ultra-low vibration and reliable cyclic durability under continuous medium-heavy load operation. The one-piece flange design removes the need for extra positioning fixtures, accelerates assembly processes, and effectively prevents shaft offset, axial play and mechanical shaking in densely arranged precision equipment layouts. Available in three universal industrial versions: F6909 open type, F6909ZZ double metal shield type and F6909-2RS double rubber sealed type, it stably performs in dry, dusty, humid and mildly corrosive indoor and outdoor working conditions. Offered in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6909 fully meets economical, sanitary, high-wear and anti-corrosion precision industrial application standards.
F6909 Open / ZZ / 2RS Structural Features
F6909 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, eliminating thermal accumulation and precision degradation during prolonged high-speed operation. It supports convenient grease replenishment and tool-free routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision machinery, it maintains stable running accuracy and long-term operational consistency.
F6909ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6909ZZ effectively blocks fine dry dust, floating particles and micro industrial debris. The non-contact protective design preserves original high-speed smoothness and dimensional precision with minimal friction loss. Featuring outstanding durability and cost performance, this model is widely applied in dry industrial workshops and long-running medium-load precision automation equipment.
F6909-2RS Double Rubber Seals: The fully sealed 2RS structure adopts double-sided contact rubber seals to comprehensively isolate moisture, water splashes, oil mist and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage, oxidation and aging, enabling long-term maintenance-free operation for humid, dusty and complex semi-corrosive industrial scenarios.
F6909 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel F6909 bearings deliver reliable wear resistance and steady heavy-load rotation, ideal for mass production and budget-sensitive precision automation projects.
304 Stainless Steel: Food-grade rust-resistant stainless steel with excellent oxidation resistance. It resists mild humid corrosion, suitable for food processing equipment, medical devices and sanitary-grade precision mechanical systems.
316 Stainless Steel: Marine-grade anti-corrosion material with strong resistance to salt spray, acid and alkali erosion. It retains stable precision in coastal high-humidity and light chemical environments for marine instruments and miniature chemical equipment.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It provides stable wear resistance and dimensional stability during continuous high-speed cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance. It withstands severe friction wear and weak corrosive conditions, ensuring long-term accurate rotation for high-end precision mechanical systems.
