F6808 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Thin Section Bearing
The F6808 flange deep groove ball bearing is a high-performance thin-section miniature bearing optimized for slim, space-constrained mechanical systems requiring reliable medium radial load capacity and consistent high-speed operational stability. Featuring a one-piece integrated flange structure and ultra-fine polished raceways, this bearing delivers superior dimensional accuracy, ultra-low vibration and excellent running smoothness during long-cycle continuous operation. The built-in flange simplifies installation, provides precise axial positioning, and effectively prevents shaft offset, axial play and mechanical shaking in compact assembly layouts. Available in three standard industrial configurations including F6808 open type, F6808ZZ double metal shield type and F6808-2RS double rubber sealed type, it reliably adapts to dry, dusty, humid and mildly corrosive working conditions. Manufactured with carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6808 meets full-spectrum industrial requirements for economical, sanitary, wear-resistant and anti-corrosion precision applications.
F6808 Open / ZZ / 2RS Structural Features
F6808 Open Type: The unsealed open structure ensures unobstructed air circulation and efficient heat dissipation, eliminating thermal accumulation and precision degradation during prolonged high-speed rotation. It supports easy grease refilling and tool-free routine maintenance with zero extra rotational resistance. Ideal for clean, dry indoor environments and fully enclosed precision micro machinery, it maintains stable running accuracy and long-term operational consistency.
F6808ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6808ZZ effectively blocks fine dry dust, floating particles and tiny industrial debris. The non-contact protective design preserves original high-speed smoothness and micro precision with minimal friction loss. Featuring stable durability and high cost performance, this model is widely used in dry industrial workshops and long-running high-speed precision micro equipment.
F6808-2RS 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 bearing runs stably and quietly in humid, dusty and complex indoor and outdoor industrial scenarios.
F6808 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel F6808 bearings provide reliable wear resistance and smooth high-speed rotation, perfectly suitable for mass production and cost-sensitive precision automation projects.
304 Stainless Steel: Food-grade stainless steel with excellent rust and oxidation resistance. It resists micro corrosion in humid and open environments, ideal 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 maintains stable structural 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 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. It withstands severe friction wear and weak corrosive conditions, ensuring long-term accurate and stable rotation for high-end micro precision mechanical systems.
