F6800 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Thin Section Bearing
The F6800 flange deep groove ball bearing is a standard thin-section high-precision flanged bearing engineered for compact, lightweight and high-speed micro mechanical systems. Featuring a slim cross-section and integrated outer flange positioning design, this bearing delivers stable radial load capacity, low vibration and excellent running smoothness under continuous cyclic operation. The one-piece flange structure simplifies mounting, enables accurate axial positioning without extra locking accessories, and effectively prevents shaft offset and operational shaking in limited installation space. Available in three mainstream industrial versions including F6800 open type, F6800ZZ double metal shield type and F6800-2RS double rubber sealed type, it adapts perfectly to dry, dusty, humid and mildly harsh workshop environments. Manufactured in five industrial-grade materials: carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6800 fully covers economical, sanitary, high-wear and anti-corrosion precision industrial application demands.
F6800 Open / ZZ / 2RS Structural Features
F6800 Open Type: The unsealed open structure allows maximum air circulation and efficient heat dissipation, eliminating thermal accumulation and precision degradation during prolonged high-speed rotation. It supports convenient grease refilling and tool-free routine maintenance with zero extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision micro machinery, it maintains consistent high running accuracy and long-cycle operational stability.
F6800ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6800ZZ 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 reliable durability and superior cost performance, this model is widely applied in dry industrial environments and long-running high-speed precision equipment.
F6800-2RS 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.
F6800 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel F6800 bearings deliver reliable wear resistance and smooth high-speed rotation for standard precision equipment, ideal for mass production and cost-sensitive automation projects.
304 Stainless Steel: Food-grade stainless steel with outstanding rust and oxidation resistance. It resists micro corrosion in humid and open environments, suitable for food processing accessories, medical devices and sanitary-grade precision machinery systems.
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 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 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.
Core Advantages And Industrial Applications
The F6800 flange thin-section bearing features a slim lightweight structure, integrated flange positioning, ultra-quiet operation and durable high-speed precision.
