R10 Miniature Deep Groove Ball Bearing | Open, ZZ, 2RS High Precision Bearings
The R10 deep groove ball bearing is a high-precision imperial miniature bearing designed for compact, space-constrained micro mechanical systems requiring stable high-speed rotation, low noise and long service life. Featuring standard imperial sizing, finely polished raceways and premium precision rolling elements, this single-row micro bearing delivers ultra-low friction, minimal vibration and consistent dimensional stability. Optimized for light-load, high-frequency cyclic operation, the R10 offers enhanced structural rigidity and reliable wear resistance, ideal for modern miniaturized precision electromechanical devices and automated micro systems. Available in three mainstream industrial configurations including open type, R10ZZ double metal shield type and R10-2RS double rubber sealed type, this imperial bearing comes with five industrial-grade materials to suit economical, sanitary, high-wear and corrosive working environments for diverse micro-precision industrial applications.
R10 Open / ZZ / 2RS Structural Features
R10 Open Type: The unsealed open structure maximizes air circulation and heat dissipation, effectively preventing thermal accumulation during prolonged high-speed continuous operation. It supports easy grease replenishment and tool-free daily maintenance without increasing rotational resistance. Perfect for clean, dry indoor workshops and fully enclosed precision micro machinery, it maintains ultra-high running accuracy and stable long-cycle performance for lightweight micro assemblies.
R10ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the R10ZZ miniature bearing effectively blocks dry fine dust, floating micro particles and tiny industrial debris. The non-contact protective design retains original high-speed smoothness and micro precision with negligible friction loss. With stable durability and excellent cost performance, it is widely used in dry working conditions for micro high-speed motors, drone precision parts, optical instruments and miniature transmission components.
R10-2RS Double Rubber Seals: The fully sealed R10-2RS variant adopts double-sided contact rubber seals to fully isolate moisture, water splashes, oil mist and corrosive fine dust. It securely locks internal lubricant to prevent leakage, oxidation and aging, realizing long-term maintenance-free operation. This versatile sealed model operates stably in humid, dusty and mildly harsh environments for portable micro precision devices and outdoor miniature electromechanical equipment.
R10 Bearing Material Performance
Carbon Steel: High cost-performance industrial material with uniform hardness and stable anti-fatigue properties. It delivers reliable wear resistance and smooth high-speed rotation for standard micro precision machinery, suitable for mass production and cost-sensitive miniature equipment projects.
304 Stainless Steel: Food-grade stainless steel with outstanding rust and oxidation resistance. It avoids micro corrosion in humid and open environments, ideal for food processing accessories and sanitary-grade micro precision equipment.
316 Stainless Steel: Marine-grade corrosion-resistant material with excellent resistance to acid, alkali and salt spray. It withstands coastal humidity and mild chemical exposure, perfect 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 cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance and structural stability. It ensures accurate and stable micro operation under severe wear and corrosive conditions, optimized for high-end micro precision mechanical systems.
