MF104 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The MF104 flange miniature bearing is a compact high-precision single-row deep groove ball bearing with an integrated flange structure, tailored for ultra-space-limited micro mechanical systems and high-speed lightweight rotary applications. Featuring a standard 4x10x4mm dimension, finely polished raceways and stable radial load capacity, this bearing delivers outstanding dimensional accuracy, ultra-low vibration and consistent high-speed operational stability. The one-piece flange design simplifies rapid installation, enables precise axial positioning, and effectively prevents shaft offset and mechanical shaking during long-term cyclic operation. Available in three mainstream industrial versions including MF104 open type, MF104ZZ double metal shield type and MF104-2RS double rubber sealed type, it reliably adapts to dry, dusty, humid and mildly harsh workshop environments. Offered in five industrial-grade materials: carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the MF104 fully meets economical, sanitary, high-wear and anti-corrosion precision industrial application requirements.
MF104 Open / ZZ / 2RS Structural Features
MF104 Open Type: The unsealed open structure ensures unobstructed air circulation and efficient heat dissipation, eliminating thermal accumulation and precision degradation during prolonged high-speed rotation. It supports convenient grease refilling and tool-free routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed micro precision machinery, it maintains ultra-high running accuracy and stable long-cycle working performance.
MF104ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the MF104ZZ effectively blocks fine dry dust, floating particles and tiny industrial debris. The non-contact protective design retains original high-speed smoothness and micro precision with minimal friction loss. Featuring reliable durability and outstanding cost performance, this model is widely applied in dry industrial environments and long-running micro high-speed precision equipment.
MF104-2RS 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, realizing long-term maintenance-free operation. This versatile sealed bearing runs stably in humid, dusty and complex indoor and outdoor industrial scenarios.
MF104 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel MF104 bearings provide reliable wear resistance and smooth high-speed rotation for standard micro precision equipment, perfectly suitable for mass production and cost-sensitive automation projects.
304 Stainless Steel: Food-grade stainless steel with superior rust and oxidation resistance. It resists micro corrosion in humid and open environments, suitable for food processing accessories, medical devices and sanitary-grade precision machinery 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, applicable for marine micro instruments and chemical miniature 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 and structural stability. 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 MF104 flange miniature bearing features an ultra-compact lightweight structure, integrated flange positioning, ultra-quiet operation and durable high-speed precision.
