16004 Deep Groove Ball Bearing | Open, ZZ, 2RS Thin-Wall Precision Bearings
The 16004 deep groove ball bearing is a high-precision thin-wall bearing engineered for compact, lightweight mechanical systems requiring precise rotation and stable operation. Featuring a slim optimized structure, polished raceways and refined rolling elements, this single-row bearing delivers ultra-low friction, outstanding dimensional accuracy and consistent high-speed performance. Compared with standard bearings, the 16004 thin-wall design saves installation space while maintaining reliable operational stability, perfectly catering to miniaturized precision equipment. It comes with three standard industrial configurations: open type, 16004ZZ double metal shield type and 16004-2RS double rubber sealed type. Available in five industrial-grade materials, it covers economical, sanitary, wear-resistant and anti-corrosion application scenarios for diverse precision industrial and commercial equipment.
16004 Open / ZZ / 2RS Structural Features
16004 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively preventing thermal accumulation during long-duration high-speed operation. It supports tool-free grease replenishment and convenient routine maintenance without generating extra rotational resistance. Ideal for clean, dry indoor environments and fully enclosed precision machinery, it sustains ultra-high running accuracy and stable long-cycle operational performance for lightweight precision systems.
16004ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, the 16004ZZ precision bearing effectively blocks dry fine dust, floating micro particles and tiny industrial debris. The non-contact protective design preserves original high-speed precision and smooth rotation with minimal friction loss. Boasting stable durability and excellent cost performance, it is widely used in dry working conditions for precision instruments, miniature high-speed motors, automation accessories and lightweight transmission equipment.
16004-2RS Double Rubber Seals: The fully sealed 16004-2RS variant adopts double-sided contact rubber seals to comprehensively isolate moisture, water splashes, oil mist and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage, oxidation and aging, realizing long-term maintenance-free operation. This sealed model stably adapts to humid, dusty and mildly harsh environments for portable precision devices and outdoor lightweight electromechanical equipment.
16004 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 conventional lightweight precision machinery, ideal for mass batch production and general industrial applications.
304 Stainless Steel: Food-grade stainless steel with superior anti-rust and anti-oxidation performance. It resists micro corrosion in humid and open environments, perfectly suitable for food processing machinery and sanitary precision electromechanical equipment.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong resistance to acid, alkali and salt spray. It withstands coastal humidity and mild chemical erosion, applicable for marine precision instruments and chemical processing lightweight 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 top-tier abrasion resistance and structural stability. It ensures accurate and stable operation under severe wear and corrosive conditions, customized for high-end industrial precision mechanical systems.
