MF85 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The MF85 flange miniature bearing is a high-precision integrated flange deep groove ball bearing designed for ultra-compact micro mechanical structures and high-speed precision rotary automation equipment. Featuring a one-piece flange positioning structure and finely polished raceways, this bearing delivers stable dimensional accuracy, ultra-low vibration and consistent long-cycle high-speed performance. The integrated flange simplifies installation, achieves accurate axial positioning, and effectively prevents shaft offset and operational shaking during continuous cyclic work. Available in three mainstream industrial specifications including MF85 open type, MF85ZZ double metal shield type and MF85-2RS double rubber sealed type, it adapts to dry, dusty, humid and mildly harsh industrial working environments. Manufactured with five industrial-grade materials: carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the MF85 fully meets economical, sanitary, high-wear and anti-corrosion precision application requirements.
MF85 Open / ZZ / 2RS Structural Features
MF85 Open Type: The unsealed open structure ensures unobstructed air circulation and efficient heat dissipation, avoiding 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 precision micro machinery, it maintains ultra-high running accuracy and stable long-term operational consistency.
MF85ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the MF85ZZ 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.
MF85-2RS 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.
MF85 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. Carbon steel MF85 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, ideal 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.
