MF94 Flange Miniature Bearing | Open, ZZ, 2RS High Precision Bearing
The MF94 flange miniature bearing is a high-precision one-piece flanged deep groove ball bearing engineered for ultra-compact micro mechanical structures and medium-load high-speed precision rotary systems. Built with an integral flange positioning structure and high-precision polished raceways, this bearing delivers excellent dimensional consistency, ultra-low noise and minimal vibration during long-cycle continuous operation. The integrated flange simplifies mounting, enables accurate axial fixation, and effectively prevents shaft deviation and mechanical shaking in limited installation spaces. Available in three standard industrial configurations: MF94 open type, MF94ZZ double metal shield type and MF94-2RS double rubber sealed type, it adapts to dry, dusty, humid and mildly corrosive working conditions. Manufactured in five industrial-grade materials including carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the MF94 meets versatile industrial requirements for cost-effective, sanitary, wear-resistant and anti-corrosion precision applications.
MF94 Open / ZZ / 2RS Structural Features
MF94 Open Type: The open non-sealed structure provides unobstructed airflow and superior heat dissipation, effectively avoiding thermal deformation and precision attenuation during prolonged high-speed rotation. It allows easy grease replenishment and tool-free daily maintenance without increasing rotational resistance. Perfect for clean, dry indoor equipment and fully enclosed micro machinery, it maintains stable high precision and long-term operational reliability.
MF94ZZ Double Metal Shields: Designed with dual non-contact steel shields, the MF94ZZ efficiently blocks fine dust, dry particles and floating industrial debris. The non-contact protective structure preserves original smooth rotation and high-speed accuracy with negligible friction loss. Offering outstanding durability and cost performance, this model is widely used for dry workshop environments and long-running micro high-speed precision devices.
MF94-2RS Double Rubber Seals: The dual-sided rubber sealed structure fully isolates moisture, water splashes, oil mist and corrosive fine particles. It firmly locks internal lubricant to prevent leakage, oxidation and grease aging, achieving long-term maintenance-free operation. This versatile bearing delivers stable performance in humid, dusty and complex indoor and outdoor industrial scenarios.
MF94 Bearing Material Performance
Carbon Steel: High cost-performance industrial material with uniform hardness and stable anti-fatigue capacity. Carbon steel MF94 bearings ensure reliable wear resistance and smooth high-speed rotation, ideal for mass production and cost-sensitive precision automation projects.
304 Stainless Steel: Food-grade stainless steel with excellent rust and oxidation resistance. It effectively resists mild corrosion in humid and open environments, suitable for medical devices, food processing machinery and sanitary-grade precision equipment.
316 Stainless Steel: Marine-grade anti-corrosion stainless steel with strong tolerance to salt spray, acid and alkali erosion. It maintains stable precision in coastal humidity and light chemical environments for marine instruments and miniature chemical equipment.
420 Stainless Steel: High-toughness martensitic stainless steel with balanced hardness and corrosion resistance. It provides stable wear resistance and precise dimensional stability during frequent high-speed cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance. It withstands heavy friction and weak corrosive conditions, supporting long-term accurate and stable rotation for high-end micro precision mechanical systems.
Core Advantages And Industrial Applications
The MF94 flange miniature bearing features a compact integrated flange design, lightweight structure, ultra-quiet operation and excellent high-speed durability. Multiple sealing grades and material options fully satisfy industrial demands for economy, sanitation, wear resistance and corrosion protection. Widely applied in miniature high-speed motors, drone precision components, optical instruments, micro transmission systems, portable precision power tools and compact medical automation equipment, the MF94 acts as a core positioning and rotary component for space-limited micro mechanical systems. It provides high-efficiency, low-noise and low-maintenance precision rotation solutions for modern miniaturized industrial and commercial precision automation devices.
