MF148 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The MF148 flange miniature bearing is a high-precision one-piece flanged deep groove ball bearing designed for ultra-compact micro mechanical structures and high-speed precision rotary automation systems. Built with an integrated flange positioning structure and finely polished raceways, this bearing delivers excellent dimensional stability, ultra-low vibration and consistent long-cycle operational accuracy. The integrated flange simplifies installation, enables precise axial positioning, and effectively prevents shaft offset and mechanical shaking during continuous cyclic operation. Available in three practical industrial versions including MF148 open type, MF148ZZ double metal shield type and MF148-2RS double rubber sealed type, it adapts perfectly 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 MF148 fully covers economical, sanitary, high-wear and anti-corrosion precision industrial application needs.
MF148 Open / ZZ / 2RS Structural Features
MF148 Open Type: The unsealed open structure achieves unobstructed air circulation and efficient heat dissipation, effectively avoiding thermal accumulation and precision degradation during prolonged high-speed rotation. It supports convenient grease refilling and tool-free daily maintenance without increasing extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed micro precision machinery, it maintains ultra-high running accuracy and stable long-term working performance.
MF148ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the MF148ZZ 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.
MF148-2RS 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.
MF148 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel MF148 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 MF148 flange miniature bearing features a compact integrated flange structure, lightweight design, ultra-quiet operation and durable high-speed precision.
