F6711 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The F6711 flange miniature bearing is a high-precision integrated flange deep groove ball bearing designed for compact micro mechanical structures and high-speed precision rotary automation systems. Adopting a one-piece flange positioning structure and finely polished raceway surface, this bearing delivers stable dimensional accuracy, ultra-low vibration and consistent high-speed rotation performance. The integrated flange simplifies installation, enables precise axial positioning, and effectively prevents shaft offset and operational shaking during long-term cyclic work. Available in three mainstream industrial types, including F6711 open type, F6711ZZ double metal shield type and F6711-2RS double rubber sealed type, it adapts to dry, dusty, humid and mildly harsh working conditions. Manufactured in five industrial-grade materials: carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6711 fully meets economical, sanitary, high-wear and anti-corrosion precision industrial application requirements.
F6711 Open / ZZ / 2RS Structural Features
F6711 Open Type: The unsealed open structure provides unobstructed air circulation and excellent heat dissipation, avoiding thermal accumulation and precision attenuation during prolonged high-speed operation. It supports easy grease refilling and tool-free daily maintenance without increasing rotational resistance. Suitable for clean, dry indoor environments and fully enclosed precision micro machinery, it maintains ultra-high running accuracy and stable long-cycle performance.
F6711ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6711ZZ effectively isolates 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 used for dry workshop environments and long-running micro high-speed precision equipment.
F6711-2RS Double Rubber Seals: The fully sealed 2RS structure adopts double-sided contact rubber seals to comprehensively block moisture, water splashes, oil mist and corrosive fine dust. It firmly locks internal lubricant 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.
F6711 Bearing Material Performance
Carbon Steel: Cost-effective industrial base material with uniform hardness and stable anti-fatigue performance. Carbon steel F6711 bearings deliver reliable wear resistance and smooth high-speed rotation for standard micro precision equipment, ideal for mass production and cost-sensitive automation projects.
304 Stainless Steel: Food-grade stainless steel with excellent rust and oxidation resistance. It prevents micro corrosion in humid and open environments, perfectly suitable for food processing parts, 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, 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 ensures 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, maintaining long-term accurate and stable rotation for high-end micro precision mechanical systems.
Core Advantages And Industrial Applications
The F6711 flange miniature bearing features an integrated flange positioning structure, compact lightweight design, ultra-quiet operation and durable high-speed precision. Three sealing grades and diversified material options fully cover industrial demands for economy, sanitation, wear resistance and anti-corrosion performance. Widely applied in miniature high-speed motors, drone precision components, optical precision instruments, micro transmission systems, portable micro power tools and compact medical devices, the F6711 acts as a core positioning and rotary component for space-limited micro mechanical systems. It provides high-efficiency, low-noise and low-maintenance precision rotation solutions for modern miniaturized industrial and commercial precision automation equipment.
