6002 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Bearings
The 6002 deep groove ball bearing is a high-performance precision component in the 6000 series, featuring larger inner diameter and upgraded rolling elements compared to the 6001 model. It delivers higher load capacity, better structural rigidity and stable rotational consistency while retaining a compact lightweight design. This single-row ball bearing reliably handles medium radial loads and incidental axial tension, supporting long-term low-noise, high-speed continuous operation. Available in three mainstream configurations, including open type, 6002ZZ double metal shield type and 6002-2RS double rubber sealed type, the 6002 series adopts five industrial-grade materials to fit economic, sanitary, high-wear and corrosive industrial environments.
6002 Open / ZZ / 2RS Structural Features
6002 Open Type: The basic unsealed open structure offers unobstructed heat dissipation and smooth grease circulation. It allows fast lubricant replacement and convenient daily maintenance without extra rotational friction. Ideal for clean, dry indoor workshops and fully enclosed precision equipment, it ensures stable high-speed operation for devices with regular maintenance cycles.
6002ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof bearing effectively blocks fine dry dust, floating particles and micro debris. The non-contact design preserves original high-speed accuracy and dynamic stability without increasing operating resistance. With outstanding durability and cost performance, it is widely used for dry production lines, micro automation systems and general precision transmission machinery.
6002-2RS Double Rubber Seals: Designed with double-sided contact rubber seals, this fully sealed variant provides comprehensive protection against moisture, water splash, oil stains and corrosive fine dust. It tightly locks internal lubricating grease to avoid leakage and contamination, achieving long-term maintenance-free operation, perfectly adapting to outdoor, humid and dusty harsh working conditions.
6002 Bearing Material Performance
Carbon Steel: Standard economical industrial material with uniform hardness and excellent anti-fatigue properties. It delivers stable wear resistance and smooth high-speed rotation for medium light-load equipment, offering supreme cost performance for mass civilian and general industrial applications.
304 Stainless Steel: Universal food-grade stainless steel with excellent atmospheric anti-rust and anti-oxidation performance. It prevents surface corrosion and precision attenuation in humid and open environments, suitable for light industry, outdoor micro devices and conventional food processing equipment.
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 accessories and light chemical precision equipment.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It provides reliable 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 operation under heavy wear and complex corrosive environments, customized for high-end electronics and industrial precision devices.
Core Advantages And Industrial Applications
The 6002 deep groove ball bearing features enhanced load capacity, compact structure, ultra-low noise and stable high-speed performance. Three sealing structures and five diversified material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion application scenarios. It is extensively applied in precision instruments, micro automation equipment, consumer electronics, small household appliances, medical miniature machinery, robot micro joints, food processing accessories and outdoor precision devices, providing stable, low-maintenance and high-efficiency precision rotation solutions for modern light and medium-duty mechanical systems.
