FR196 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Miniature Bearing
The FR196 flange deep groove ball bearing is a high-precision miniature flange bearing designed for ultra-compact, space-limited micro mechanical systems requiring stable load capacity, precise flange positioning and consistent long-term high-speed operation. Featuring an integrated one-piece flange and ultra-fine polished deep groove raceways, this bearing delivers exceptional dimensional stability, ultra-low vibration and quiet rotary performance during continuous cyclic operation. The solid integrated flange eliminates extra positioning fasteners, accelerates precision assembly, and effectively prevents shaft offset, axial play and micro mechanical shaking in densely configured miniature equipment layouts. Available in three standard industrial versions: FR196 open type, FR196ZZ double metal shield type and FR196-2RS double rubber sealed type, it reliably operates in dry, dusty, humid and mildly corrosive indoor and outdoor working conditions. Offered in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the FR196 fully meets economical, sanitary, high-wear and anti-corrosion miniature precision industrial application requirements.
FR196 Open / ZZ / 2RS Structural Features
FR196 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, preventing thermal accumulation and precision degradation during prolonged high-speed micro operation. It supports convenient grease replenishment and tool-free routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed miniature precision machinery, it maintains stable running accuracy and extended service life.
FR196ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the FR196ZZ effectively blocks fine dry dust, floating particles and micro industrial debris. The non-contact protective design retains original high-speed smoothness and micro precision with minimal friction loss. Featuring reliable structural durability and excellent cost performance, this model is widely applied in dry industrial workshops and long-running miniature precision automation equipment.
FR196-2RS 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 for humid, dusty and complex micro mechanical working scenarios.
FR196 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel FR196 bearings deliver reliable wear resistance and smooth high-speed rotation, ideal for mass production and budget-sensitive miniature precision automation projects.
304 Stainless Steel: Food-grade rust-resistant stainless steel with excellent oxidation resistance. It resists micro corrosion in humid and open environments, suitable for miniature food processing accessories, compact medical devices and sanitary-grade micro precision mechanical 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 micro marine instruments and miniature chemical 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. It withstands severe friction wear and weak corrosive conditions, ensuring long-term accurate and stable rotation for high-end micro precision mechanical systems.
