MR106 Miniature Deep Groove Ball Bearing | Open, ZZ, 2RS High Precision Bearings
The MR106 deep groove ball bearing is a high-precision miniature rolling bearing developed for ultra-compact, space-constrained micro mechanical systems. Featuring optimized miniaturized dimensions, finely polished raceways and precision rolling elements, this single-row bearing delivers ultra-low friction, minimal vibration and stable high-speed rotational stability. Designed for long-term light-load and high-frequency cyclic operation, the MR106 maintains reliable structural rigidity and precise dimensional accuracy, perfectly adapting to modern miniaturized precision electromechanical equipment. This series offers three mainstream industrial specifications: open type, MR106ZZ double metal shield type and MR106-2RS double rubber sealed type. With five industrial-grade material options, it flexibly meets economical, sanitary, wear-resistant and anti-corrosion operational demands for diverse micro-precision industrial scenarios.
MR106 Open / ZZ / 2RS Structural Features
MR106 Open Type: The unsealed open structure achieves unobstructed air circulation and efficient heat dissipation, effectively avoiding thermal accumulation during prolonged high-speed micro operation. It supports tool-free grease replenishment and simple daily maintenance without generating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed micro precision machinery, it sustains ultra-high running accuracy and stable long-cycle performance for lightweight micro mechanical assemblies.
MR106ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the MR106ZZ miniature bearing effectively blocks fine dry dust, floating micro particles and tiny industrial debris. The non-contact protective design preserves original high-speed smoothness and micro precision with negligible friction loss. Boasting stable durability and excellent cost performance, it is widely applied in dry working environments for micro high-speed motors, drone precision components, optical instruments and miniature transmission systems.
MR106-2RS Double Rubber Seals: The fully sealed MR106-2RS variant adopts double-sided contact rubber seals to comprehensively isolate moisture, water splashes, oil mist and corrosive fine dust. It tightly locks internal micro lubricating grease to prevent leakage, oxidation and aging, enabling long-term maintenance-free operation. This versatile sealed model operates stably in humid, dusty and mildly harsh scenarios for portable micro precision devices and outdoor miniature electromechanical equipment.
MR106 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. It provides reliable wear resistance and smooth high-speed rotation for conventional micro precision machinery, ideal for mass batch production and cost-sensitive miniature equipment projects.
304 Stainless Steel: Food-grade stainless steel with excellent anti-rust and anti-oxidation performance. It resists micro corrosion in humid and open environments, perfectly suitable for food processing accessories and sanitary micro precision equipment.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong resistance to acid, alkali and salt spray erosion. It withstands coastal high humidity and mild chemical corrosion, applicable for marine micro instruments and light chemical miniature machinery.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It maintains stable wear resistance and precise dimensional stability during continuous high-speed micro cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It sustains accurate and stable micro operation under severe wear and corrosive conditions, customized for high-end micro precision mechanical systems.
