F6809 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Thin Section Bearing
The F6809 flange deep groove ball bearing is a high-precision thin-section miniature bearing designed for slim, space-limited mechanical systems requiring stable medium-load capacity and long-term high-speed rotary accuracy. Featuring an integrated one-piece flange structure and finely polished raceways, this bearing delivers outstanding dimensional stability, ultra-low vibration and consistent operational smoothness during continuous cyclic work. The integral outer flange enables fast, tool-free installation and precise axial positioning, effectively preventing shaft offset, axial play and mechanical shaking in compact equipment layouts. Available in three mainstream industrial types: F6809 open type, F6809ZZ double metal shield type and F6809-2RS double rubber sealed type, it reliably adapts to dry, dusty, humid and mildly corrosive working environments. Offered in five industrial-grade materials including carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6809 fully meets economical, sanitary, high-wear and anti-corrosion precision industrial application requirements.
F6809 Open / ZZ / 2RS Structural Features
F6809 Open Type: The unsealed open structure features unobstructed air circulation and excellent heat dissipation, eliminating thermal accumulation and precision attenuation during prolonged high-speed operation. It supports convenient grease refilling and routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision micro machinery, it maintains stable running accuracy and long-cycle operational consistency.
F6809ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6809ZZ effectively blocks fine dry dust, floating particles and tiny industrial debris. The non-contact protective design retains original high-speed smoothness and micro precision with minimal friction loss. With reliable durability and superior cost performance, this model is widely applied in dry industrial environments and long-running high-speed precision micro equipment.
F6809-2RS 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, realizing long-term maintenance-free operation. This versatile sealed bearing runs stably in humid, dusty and complex indoor and outdoor industrial scenarios.
F6809 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel F6809 bearings provide reliable wear resistance and smooth high-speed rotation for standard precision equipment, perfectly suitable for mass production and cost-sensitive automation projects.
316 Stainless Steel: Marine-grade anti-corrosion material with strong tolerance to salt spray, acid and alkali erosion. It maintains stable structural 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 precise dimensional stability during continuous high-speed cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It withstands severe friction wear and weak corrosive conditions, ensuring long-term accurate and stable rotation for high-end micro precision mechanical systems.
