F6802 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Thin Section Bearing
The F6802 flange deep groove ball bearing is a high-precision thin-section miniature bearing tailored for ultra-slim, space-restricted micro mechanical systems that require stable high-speed rotation and precise axial positioning. Built with an integrated one-piece outer flange and finely polished raceways, this bearing delivers excellent dimensional stability, ultra-low vibration and reliable radial load capacity during long-cycle continuous operation. The integral flange design eliminates additional positioning fixtures, greatly simplifies assembly procedures, and effectively prevents shaft offset and mechanical shaking in compact installation spaces. Available in three standard industrial specifications including F6802 open type, F6802ZZ double metal shield type and F6802-2RS double rubber sealed type, it stably adapts to dry, dusty, humid and mildly harsh industrial working environments. Manufactured with five industrial-grade materials: carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the F6802 fully meets economical, sanitary, high-wear and anti-corrosion precision application requirements for diverse industrial scenarios.
F6802 Open / ZZ / 2RS Structural Features
F6802 Open Type: The unsealed open structure features unobstructed air circulation and efficient heat dissipation, effectively avoiding thermal deformation and precision attenuation during prolonged high-speed operation. It supports convenient grease refilling and tool-free routine maintenance without generating extra rotational resistance. Ideal for clean, dry indoor environments and fully enclosed precision micro machinery, it maintains stable running accuracy and long-term operational consistency.
F6802ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the F6802ZZ efficiently blocks fine dry dust, floating particles and tiny industrial debris. The non-contact protective structure retains original high-speed smoothness and micro precision with minimal friction loss. Boasting reliable durability and outstanding cost performance, this model is widely applied in dry workshop environments and long-running micro high-speed precision equipment.
F6802-2RS 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 firmly 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.
F6802 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel F6802 bearings provide reliable wear resistance and smooth high-speed rotation for standard 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.
