F6704 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The F6704 flange miniature bearing is a high-precision one-piece flanged deep groove ball bearing developed for compact micro mechanical systems and high-speed precision rotation equipment. Featuring an integrated flange positioning structure and optimized internal rolling raceway, this bearing delivers stable dimensional accuracy, ultra-low vibration and consistent high-speed operating performance. The built-in flange design simplifies mounting, achieves precise axial positioning and effectively prevents axial deviation during long-cycle continuous operation. Available in three mainstream industrial versions, including F6704 open type, F6704ZZ double metal shield type and F6704-2RS double rubber sealed type, it adapts to dry, dusty, humid and mildly harsh working environments. Offered in five industrial-grade materials including carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6704 fully meets economic, sanitary, high-wear and anti-corrosion industrial application demands.
F6704 Open / ZZ / 2RS Structural Features
F6704 Open Type: The unsealed open structure ensures unobstructed air circulation and excellent heat dissipation, effectively avoiding thermal accumulation and precision loss during prolonged high-speed rotation. It supports convenient grease replenishment and tool-free daily maintenance without increasing rotational resistance. Suited for clean, dry indoor workshops and fully enclosed precision micro machinery, it maintains ultra-high running accuracy and stable long-term cyclic performance.
F6704ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6704ZZ reliably blocks dry fine dust, floating particles and tiny industrial debris. The non-contact protective structure reserves original smooth rotation and high-speed precision with negligible friction loss. With outstanding durability and cost performance, it is widely used for dry industrial environments and long-running micro high-speed equipment.
F6704-2RS Double Rubber Seals: The fully sealed F6704-2RS adopts double-sided contact rubber seals to isolate moisture, splash water, oil mist and corrosive fine dust. It securely locks internal lubricant to prevent leakage, oxidation and aging, realizing long-term maintenance-free operation. This versatile sealed model runs stably in humid, dusty and complex workshop and outdoor working conditions.
F6704 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. It provides reliable wear resistance and smooth high-speed rotation for standard micro precision equipment, ideal for mass production and cost-sensitive industrial automation projects.
304 Stainless Steel: Food-grade stainless steel with superior rust and oxidation resistance. It effectively resists micro corrosion in humid and open environments, perfectly 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 humidity and light chemical environments, applicable for marine micro instruments and light chemical miniature mechanical 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 frequent 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.
