FR14 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Miniature Bearing
The FR14 flange deep groove ball bearing is a large-bore heavy-duty miniature flange bearing designed for compact space-limited mechanical systems requiring superior load capacity, rigid structural stability and long-term consistent high-speed operation. Built with a thickened integrated one-piece flange and ultra-precision polished deep groove raceways, this bearing delivers excellent dimensional accuracy, ultra-low vibration and outstanding wear resistance during continuous cyclic heavy-load operation. The integrated flange structure eliminates extra positioning fasteners, simplifies rapid precision assembly, and effectively prevents shaft offset, axial play and mechanical shaking in densely arranged compact equipment layouts. Available in three standard industrial specifications: FR14 open type, FR14ZZ double metal shield type and FR14-2RS double rubber sealed type, it stably adapts to dry, dusty, humid and mildly corrosive indoor and outdoor working environments. Offered in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the FR14 fully meets economical, sanitary, high-wear and anti-corrosion miniature precision industrial application requirements.
FR14 Open / ZZ / 2RS Structural Features
FR14 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, avoiding thermal accumulation and precision degradation during prolonged high-speed and heavy-load operation. It supports convenient grease refilling and tool-free routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision micro machinery, it maintains stable running accuracy and long-cycle operational consistency.
FR14ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the FR14ZZ effectively blocks fine dry dust, floating particles and micro industrial debris. The non-contact protective design retains original high-speed smoothness and dimensional 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 heavy-load miniature precision automation equipment.
FR14-2RS 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 semi-corrosive industrial scenarios.
FR14 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel FR14 bearings deliver reliable wear resistance and stable heavy-load 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 food processing machinery, medical devices and sanitary-grade 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 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.
Core Advantages And Industrial Applications
The FR14 large-bore miniature flange bearing features a thickened reinforced compact structure, upgraded heavy-load capacity, integrated flange positioning, ultra-quiet operation and durable high-speed stability.
