F6708 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The F6708 flange miniature bearing is a high-precision one-piece flanged deep groove ball bearing designed for compact micro mechanical structures and high-speed precision rotary automation equipment. Built with an integrated flange positioning structure and finely polished smooth raceways, this bearing delivers stable dimensional accuracy, ultra-low vibration and consistent high-speed operation stability. The integrated flange optimizes assembly procedures, achieves accurate axial positioning, and effectively prevents shaft offset and operational shaking during long-cycle continuous work. Available in three classic industrial specifications including F6708 open type, F6708ZZ double metal shield type and F6708-2RS double rubber sealed type, it flexibly adapts to dry, dusty, humid and mildly harsh working environments. Manufactured with five industrial-grade materials: carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6708 fully meets economical, sanitary, high-wear and anti-corrosion industrial application demands.
F6708 Open / ZZ / 2RS Structural Features
F6708 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively avoiding thermal accumulation and precision degradation during prolonged high-speed rotation. It supports convenient grease replenishment and tool-free daily maintenance without generating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision micro machinery, it maintains ultra-high running accuracy and stable long-cycle performance.
F6708ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6708ZZ 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 excellent cost performance, this model is widely applied in dry industrial environments and long-running micro high-speed precision equipment.
F6708-2RS Double Rubber Seals: The fully sealed F6708-2RS 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.
F6708 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel F6708 bearings provide reliable wear resistance and smooth high-speed rotation for standard micro precision equipment, perfectly suitable for mass production and cost-sensitive automation projects.
304 Stainless Steel: Food-grade stainless steel with superior rust and oxidation resistance. It resists micro corrosion in humid and open environments, ideal 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, 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 delivers 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 F6708 flange miniature bearing features an integrated flange positioning structure, compact lightweight design, ultra-quiet operation and durable high-speed precision.
