F6801 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Thin Section Bearing
The F6801 flange deep groove ball bearing is a high-precision thin-section miniature bearing designed for slim, space-constrained micro mechanical systems requiring stable high-speed rotation and accurate axial positioning. Featuring an integrated one-piece outer flange and finely polished raceways, this bearing offers excellent dimensional stability, low vibration and consistent radial load capacity during long-cycle continuous operation. The built-in flange eliminates extra positioning fixtures, simplifies assembly and effectively prevents shaft offset and mechanical shaking in compact installation spaces. Available in three standard industrial types: F6801 open type, F6801ZZ double metal shield type and F6801-2RS double rubber sealed type, it adapts to dry, dusty, humid and mildly harsh working environments. Offered in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6801 meets full-spectrum industrial demands for economical, sanitary, wear-resistant and anti-corrosion precision applications.
F6801 Open / ZZ / 2RS Structural Features
F6801 Open Type: The unsealed open structure delivers unobstructed airflow and superior heat dissipation, avoiding thermal deformation and precision loss during prolonged high-speed running. It allows easy grease refilling and tool-free maintenance without increasing rotational resistance. Ideal for clean, dry indoor and fully enclosed precision equipment, it maintains stable accuracy and long-term operational consistency.
F6801ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6801ZZ effectively blocks fine dust, dry particles and floating workshop debris. The non-contact protective structure retains original high-speed smoothness with minimal friction loss. With reliable durability and high cost performance, this model is widely used for dry industrial environments and long-running micro precision machinery.
F6801-2RS Double Rubber Seals: The fully sealed 2RS structure adopts double-sided contact rubber seals to isolate moisture, water splashes, oil mist and corrosive fine dust. It locks internal lubricant firmly to prevent grease leakage, oxidation and aging, achieving long-term maintenance-free operation. This versatile bearing runs stably in humid, dusty and complex indoor and outdoor working scenarios.
F6801 Bearing Material Performance
Carbon Steel: Cost-effective industrial base material with uniform hardness and stable anti-fatigue performance. Carbon steel F6801 bearings provide reliable wear resistance and smooth rotation, perfect for mass production and budget-sensitive precision automation projects.
304 Stainless Steel: Food-grade rust-resistant stainless steel with excellent oxidation resistance. It prevents micro corrosion in humid and open environments, suitable for food processing parts, medical devices and sanitary-grade precision systems.
316 Stainless Steel: Marine-grade anti-corrosion material resistant to salt spray, acid and alkali erosion. It maintains 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 with balanced hardness and corrosion resistance. It delivers stable wear resistance and dimensional stability during frequent high-speed cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance. It withstands heavy friction and weak corrosion, ensuring long-term accurate rotation for high-end micro precision mechanical systems.
Core Advantages And Industrial Applications
The F6801 thin-section flange bearing features a slim lightweight structure, integrated flange positioning, ultra-quiet operation and outstanding high-speed durability. Multiple sealing grades and diversified material options fully cover industrial requirements for cost efficiency, sanitation, wear resistance and corrosion protection. Widely applied in miniature high-speed motors, drone precision assemblies, robotic micro joints, optical instruments, micro transmission systems and compact medical automation equipment, the F6801 is a core rotary and positioning component for ultra-thin space-limited mechanical structures. It provides stable, low-noise and low-maintenance precision rotation solutions for modern miniaturized industrial and commercial precision automation devices.
