MR82X Miniature Deep Groove Ball Bearing | Open, ZZ, 2RS High Precision Bearings
The MR82X deep groove ball bearing is a high-precision miniature bearing engineered for ultra-compact, space-limited micro mechanical systems. Featuring tiny dimensional specifications, finely polished raceways and precision rolling elements, this single-row micro bearing delivers ultra-low friction, minimal vibration and consistent high-speed stability. Optimized for light-load, high-precision cyclic operation, the MR82X model maintains outstanding dimensional accuracy and long operational lifespan despite its miniature size. It is available in three standard industrial configurations: open type, MR82XZZ double metal shield type and MR82X-2RS double rubber sealed type. Offered in five industrial-grade materials, it fully adapts to economical, sanitary, wear-resistant and anti-corrosion working environments for diverse micro-precision industrial and commercial applications.
MR82X Open / ZZ / 2RS Structural Features
MR82X Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively preventing thermal fatigue during prolonged high-speed micro-operation. It supports convenient grease replenishment and simple routine maintenance without generating extra rotational resistance. Ideal for clean, dry indoor precision instruments and fully enclosed micro machinery, it maintains ultra-high running accuracy and stable long-cycle performance for lightweight micro mechanical systems.
MR82XZZ Double Metal Shields: Equipped with dual non-contact steel shields, the MR82XZZ 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. Featuring reliable durability and excellent cost performance, it is widely applied in dry working conditions for micro motors, drone actuators, optical instruments and miniature transmission assemblies.
MR82X-2RS Double Rubber Seals: The fully sealed MR82X-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, realizing 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 lightweight micro electromechanical systems.
MR82X 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 micro-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 miniature 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.
