FR12-14 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Micro Bearing
The FR12-14 flange deep groove ball bearing is a large-bore high-load micro flange bearing designed for space-constrained compact mechanical systems requiring superior radial load capacity, rigid fixed positioning and stable long-duration high-speed operation. Featuring a thickened one-piece integrated flange and ultra-fine mirror-polished deep groove raceways, this bearing delivers excellent structural rigidity, ultra-low vibration and consistent rotary accuracy under continuous cyclic heavy loads. The integral flange structure eliminates additional positioning fasteners, simplifies rapid precision assembly, and effectively prevents shaft offset, axial play and mechanical shaking in densely arranged miniature equipment layouts. Available in three standard industrial versions: FR12-14 open type, FR12-14ZZ double metal shield type and FR12-14-2RS double rubber sealed type, it reliably 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 FR12-14 fully meets economical, sanitary, high-wear and anti-corrosion micro precision industrial application requirements.
FR12-14 Open / ZZ / 2RS Structural Features
FR12-14 Open Type: The unsealed open structure supports unobstructed air circulation and efficient heat dissipation, preventing thermal accumulation and precision degradation during prolonged high-speed heavy-load operation. It allows convenient grease refilling and tool-free routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed compact precision machinery, it maintains stable running accuracy and long-term operational consistency.
FR12-14ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the FR12-14ZZ effectively blocks fine dry dust, floating particles and micro industrial debris. The non-contact protective design preserves original high-speed smoothness and dimensional precision with minimal friction loss. Boasting reliable structural durability and outstanding cost performance, this model is widely applied in dry industrial workshops and long-running heavy-load miniature precision automation equipment.
FR12-14-2RS 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 avoid leakage, oxidation and aging, enabling long-term maintenance-free operation for humid, dusty and complex semi-corrosive micro mechanical working scenarios.
FR12-14 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel FR12-14 bearings deliver reliable wear resistance and stable heavy-load high-speed rotation, ideal for mass production and budget-sensitive compact precision automation projects.
304 Stainless Steel: Food-grade rust-resistant stainless steel with excellent oxidation and corrosion resistance. It withstands mild humid corrosion, suitable for miniature food processing equipment, sanitary accessories and compact medical precision devices.
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 miniature chemical equipment.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It ensures 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 resists severe friction wear and weak corrosive conditions, supporting long-term accurate and stable rotation for high-end micro precision mechanical systems.
Core Advantages And Industrial Applications
The FR12-14 large-bore micro flange bearing features a thickened reinforced compact structure, upgraded heavy-load capacity, integrated flange positioning, ultra-quiet operation and durable high-speed stability.
