R6 Miniature Deep Groove Ball Bearing | Open, ZZ, 2RS High Precision Bearings
The R6 deep groove ball bearing is a high-precision imperial miniature bearing designed for compact, space-restricted micro mechanical systems requiring stable high-speed rotation and long service life. Built with standard imperial sizing, mirror-polished raceways and precision rolling elements, this single-row micro bearing offers ultra-low friction, minimal vibration and outstanding rotational stability. Optimized for light-load, high-frequency cyclic operation, the R6 maintains reliable structural rigidity and consistent dimensional accuracy, perfectly fitting modern miniaturized precision electromechanical devices. Available in three industrial configurations including open type, R6ZZ double metal shield type and R6-2RS double rubber sealed type, this imperial bearing features five industrial-grade material options to suit economical, sanitary, high-wear and corrosive working environments for diverse micro-precision applications.
R6 Open / ZZ / 2RS Structural Features
R6 Open Type: The unsealed open structure delivers unobstructed airflow and efficient heat dissipation, effectively preventing thermal fatigue during prolonged high-speed micro operation. It supports easy grease refilling and tool-free routine maintenance without adding extra rotational resistance. Ideal for clean, dry indoor environments and fully enclosed micro precision machinery, it sustains ultra-high running accuracy and stable long-cycle performance for lightweight micro mechanical assemblies.
R6ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the R6ZZ miniature bearing reliably 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. Offering excellent durability and cost performance, it is widely used in dry working conditions for micro high-speed motors, drone precision components, optical instruments and miniature transmission systems.
R6-2RS Double Rubber Seals: The fully sealed R6-2RS variant adopts double-sided contact rubber seals to fully isolate moisture, water splashes, oil mist and corrosive fine dust. It securely locks internal micro lubricant 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.
R6 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 standard micro precision machinery, ideal for mass production and cost-sensitive miniature equipment projects.
304 Stainless Steel: Food-grade stainless steel with superior rust and oxidation resistance. It prevents 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 tolerance to acid, alkali and salt spray erosion. It withstands coastal humidity and mild chemical exposure, 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 ensures accurate and stable micro operation under severe wear and corrosive conditions, optimized for high-end micro precision mechanical systems.
