FR10-12 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Micro Bearing
The FR10-12 flange deep groove ball bearing is a high-load micro flange bearing tailored for compact space-restricted mechanical systems requiring larger inner diameter, rigid positioning and stable long-term high-speed operation. Built with a thickened integrated one-piece flange and high-precision mirror-polished raceways, this bearing delivers superior structural rigidity, minimal vibration and consistent rotary accuracy under continuous cyclic loads. The integrated flange design eliminates extra locking fixtures, speeds up assembly procedures, and effectively prevents shaft offset, axial play and mechanical shaking in densely configured miniature equipment layouts. Available in three mainstream industrial versions: FR10-12 open type, FR10-12ZZ double metal shield type and FR10-12-2RS double rubber sealed type, it performs steadily in dry, dusty, humid and mildly corrosive indoor and outdoor working conditions. Manufactured in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the FR10-12 fully satisfies economical, sanitary, high-wear and anti-corrosion micro precision industrial application requirements.
FR10-12 Open / ZZ / 2RS Structural Features
FR10-12 Open Type: The unsealed open structure enables unobstructed air circulation and rapid 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 environments and fully enclosed precision micro machinery, it maintains stable running accuracy and long-cycle operational consistency.
FR10-12ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the FR10-12ZZ effectively blocks fine dust, floating particles and micro industrial debris. The non-contact protective structure retains original high-speed smoothness and dimensional precision with low friction loss. Featuring outstanding durability and cost performance, this model is widely adopted in dry industrial workshops and long-running miniature precision automation equipment.
FR10-12-2RS 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 particles. It firmly locks internal lubricating grease to prevent leakage, oxidation and aging, achieving long-term maintenance-free operation for humid, dusty and complex micro mechanical working scenarios.
FR10-12 Bearing Material Performance
Carbon Steel: High cost-effective industrial base material with uniform hardness and stable anti-fatigue performance. Carbon steel FR10-12 bearings offer reliable wear resistance and smooth high-speed rotation, suitable for mass production and budget-sensitive miniature automation projects.
304 Stainless Steel: Food-grade rust-proof stainless steel with excellent oxidation resistance. It resists mild humid corrosion, ideal for food processing miniature parts, sanitary equipment and compact medical precision devices.
316 Stainless Steel: Marine-grade anti-corrosion stainless steel with strong resistance to salt spray, acid and alkali erosion. It maintains stable 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 provides stable wear resistance and dimensional stability during repeated high-speed cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance. It withstands heavy friction and weak corrosion, supporting long-term accurate rotation for high-end micro precision mechanical systems.
