F6803 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Thin Section Bearing
The F6803 flange deep groove ball bearing is a high-precision thin-section miniature bearing designed for ultra-compact, slim-profile mechanical systems requiring stable high-speed rotation and accurate axial positioning. Featuring an integrated one-piece flange structure and ultra-fine polished raceways, this bearing delivers outstanding dimensional stability, low vibration and reliable radial load capacity during long-cycle continuous operation. The built-in flange eliminates extra locking components, streamlines assembly and effectively prevents shaft offset and mechanical shaking in space-limited installations. Available in three standard industrial configurations: F6803 open type, F6803ZZ double metal shield type and F6803-2RS double rubber sealed type, it adapts stably to dry, dusty, humid and mildly harsh working environments. Manufactured in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6803 meets full-range industrial requirements for economical, sanitary, wear-resistant and anti-corrosion precision applications.
F6803 Open / ZZ / 2RS Structural Features
F6803 Open Type: The unsealed open structure ensures unobstructed airflow and efficient heat dissipation, avoiding thermal accumulation and precision degradation during prolonged high-speed operation. It supports easy grease replenishment and tool-free routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision micro machinery, it maintains consistent high running accuracy and long-term operational stability.
F6803ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6803ZZ 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. Featuring stable durability and excellent cost performance, this model is widely used in dry industrial environments and long-running high-speed precision micro equipment.
F6803-2RS 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, enabling long-term maintenance-free operation. This versatile bearing runs reliably in humid, dusty and complex indoor and outdoor industrial scenarios.
F6803 Bearing Material Performance
Carbon Steel: High cost-performance industrial material with uniform hardness and stable anti-fatigue properties. Carbon steel F6803 bearings deliver reliable wear resistance and smooth high-speed rotation, ideal for mass production and cost-sensitive precision automation projects.
304 Stainless Steel: Food-grade stainless steel with superior rust and oxidation resistance. It resists micro corrosion in humid and open environments, suitable for food processing equipment, medical devices and sanitary-grade precision mechanical systems.
316 Stainless Steel: Marine-grade anti-corrosion material with excellent resistance 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 balancing moderate corrosion resistance and high surface hardness. It provides stable wear resistance and precise dimensional stability during frequent 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 systems.
Core Advantages And Industrial Applications
The F6803 thin-section flange bearing features an ultra-slim lightweight structure, integrated flange positioning, ultra-quiet operation and durable high-speed precision.
