6004 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Precision Bearings
The 6004 deep groove ball bearing is a medium-sized high-performance model in the 6000 series, upgraded from the 6003 variant with enlarged rolling elements and reinforced raceway structure. It features higher radial and axial load capacity, enhanced structural rigidity and exceptional running stability while retaining a compact, lightweight design. This single-row deep groove ball bearing supports stable low-noise, high-speed continuous operation under medium cyclic loads, serving as a core precision component for various light and medium-duty transmission equipment. The 6004 series is available in three mainstream configurations: open type, 6004ZZ double metal shield type and 6004-2RS double rubber sealed type, with five industrial-grade material options to adapt to economic, sanitary, wear-resistant and corrosive working environments.
6004 Open / ZZ / 2RS Structural Features
6004 Open Type: Adopting a fully unsealed open structure, this basic version delivers unobstructed heat dissipation and smooth internal grease circulation. It enables convenient lubricant replacement and simple daily maintenance without extra rotational friction. Ideal for clean, dry indoor workshops and fully enclosed precision machinery, it maintains consistent high-speed precision during long-cycle operation with regular maintenance schedules.
6004ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof bearing effectively blocks fine dry dust, floating particles and micro workshop debris. The non-contact design preserves original high-speed performance and rotational stability with zero additional resistance. Boasting high cost performance and durable structure, it is widely used for dry production lines, micro automation equipment and general precision transmission systems.
6004-2RS Double Rubber Seals: Designed with double-sided contact rubber seals, this fully sealed variant provides comprehensive protection against moisture, splash water, oil stains and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage and contamination, realizing long-term maintenance-free operation, perfectly adapting to outdoor, humid, dusty and other harsh industrial working conditions.
6004 Bearing Material Performance
Carbon Steel: Standard economical industrial material with uniform hardness and excellent anti-fatigue properties. It offers stable wear resistance and smooth high-speed rotation for medium-load precision equipment, delivering outstanding cost performance for civilian and general industrial mass applications.
304 Stainless Steel: Food-grade anti-oxidation stainless steel with excellent atmospheric rust resistance. It avoids surface corrosion and precision attenuation in humid and open environments, suitable for light industry, outdoor micro devices and conventional food processing machinery.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with superior acid, alkali and salt spray tolerance. It withstands mild chemical erosion and coastal high-humidity conditions, ideal for sanitary processing, marine auxiliary equipment and light chemical precision devices.
420 Stainless Steel: Martensitic high-toughness stainless steel balancing moderate corrosion resistance and high surface hardness. It features excellent anti-wear and anti-impact performance, perfect for long-cycle precision moving parts requiring stable dimensional accuracy.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It maintains precise and stable operation under heavy wear and complex corrosive environments, customized for high-end electronics and industrial precision equipment.
Core Advantages And Industrial Applications
The 6004 deep groove ball bearing integrates upgraded load capacity, compact structure, ultra-low noise and stable high-speed performance. Three diversified sealing structures and five material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion application scenarios. It is extensively applied in precision instruments, micro automation machinery, consumer electronics, small household appliances, medical miniature devices, robot micro joints, food processing accessories and outdoor precision equipment, providing reliable, low-maintenance and high-efficiency precision rotation solutions for modern light and medium-duty mechanical systems.
