FR1-5 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Micro Bearing
The FR1-5 flange deep groove ball bearing is an ultra-compact high-precision micro flange bearing engineered for miniature space-restricted mechanical systems requiring lightweight structure, accurate positioning and stable long-cycle high-speed operation. Featuring an integrally molded mini flange and finely polished deep groove raceways, this bearing delivers superior dimensional stability, ultra-low vibration and consistent rotary smoothness during continuous cyclic work. The one-piece flange design eliminates extra locking fasteners, accelerates micro assembly efficiency, and effectively prevents shaft offset and axial play in ultra-compact precision equipment layouts. Available in three standard industrial versions: FR1-5 open type, FR1-5ZZ double metal shield type and FR1-5-2RS double rubber sealed type, it reliably operates in dry, dusty, humid and mildly corrosive indoor and outdoor environments. Offered in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the FR1-5 fully meets economical, sanitary, high-wear and anti-corrosion micro precision industrial application demands.
FR1-5 Open / ZZ / 2RS Structural Features
FR1-5 Open Type: The unsealed open structure enables unobstructed air flow and efficient heat dissipation, preventing thermal accumulation and precision attenuation during prolonged high-speed micro operation. It supports convenient grease refilling 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 long-term operational consistency.
FR1-5ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the FR1-5ZZ effectively blocks fine dry dust, floating particles and micro industrial debris. The non-contact protective structure preserves original high-speed smoothness and micro precision with minimal friction loss. Featuring reliable durability and excellent cost performance, this model is widely applied in dry industrial workshops and long-running miniature precision automation equipment.
FR1-5-2RS 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, realizing long-term maintenance-free operation for humid, dusty and complex micro equipment working scenarios.
FR1-5 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel FR1-5 bearings provide 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 parts, 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.
