F6901 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Thin Section Bearing
The F6901 flange deep groove ball bearing is an ultra-thin high-precision miniature bearing designed for ultra-slim, space-constrained micro mechanical systems requiring lightweight structure and stable high-speed rotary performance. Featuring an integrated one-piece flange and finely polished deep groove raceways, this thin-section bearing delivers accurate dimensional stability, ultra-low vibration and smooth rotation during long-cycle continuous operation. The integrated flange eliminates extra positioning fixtures, simplifies rapid assembly, and effectively prevents shaft offset and axial play in compact precision equipment layouts. Available in three mainstream industrial specifications: F6901 open type, F6901ZZ double metal shield type and F6901-2RS double rubber sealed type, it reliably adapts to dry, dusty, humid and mildly corrosive working environments. Manufactured with carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6901 fully meets economical, sanitary, high-wear and anti-corrosion precision industrial application requirements.
F6901 Open / ZZ / 2RS Structural Features
F6901 Open Type: The unsealed open structure achieves unobstructed air circulation and efficient heat dissipation, avoiding thermal accumulation and precision degradation during prolonged high-speed operation. It supports convenient grease refilling and tool-free routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed micro precision machinery, it maintains stable running accuracy and long-term operational consistency.
F6901ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6901ZZ 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 reliable durability and outstanding cost performance, this model is widely applied in dry industrial environments and long-running high-speed precision micro equipment.
F6901-2RS 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, realizing long-term maintenance-free operation. This versatile sealed bearing runs stably in humid, dusty and complex indoor and outdoor industrial scenarios.
F6901 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel F6901 bearings provide reliable wear resistance and smooth high-speed rotation, perfectly suitable 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, 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 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.
