6202 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Mini Bearings
The 6202 deep groove ball bearing is a high-precision miniature light-duty component in the 6200 series, featuring upgraded rolling elements and reinforced raceway structure compared to the 6201 model. This single-row deep groove ball bearing delivers improved load capacity, enhanced structural rigidity and stable dimensional stability while retaining a compact, lightweight design. It supports low-friction, ultra-quiet and consistent high-speed cyclic operation, making it ideal for miniature precision transmission and lightweight electromechanical systems. The 6202 series offers three standard configurations: open type, 6202ZZ double metal shield type and 6202-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, wear-resistant and corrosive industrial working scenarios.
6202 Open / ZZ / 2RS Structural Features
6202 Open Type: The unsealed open structure ensures unobstructed air circulation and efficient heat dissipation during continuous high-speed operation. It allows fast lubricant replacement and effortless routine maintenance without generating extra rotational resistance. Designed for clean, dry indoor environments and fully enclosed precision micro machinery, it maintains stable running accuracy and long-term operational consistency under light cyclic loads.
6202ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this professional dust-proof bearing effectively blocks fine dry dust, tiny floating particles and micro workshop debris. The non-contact structure preserves original high-speed precision and rotational smoothness with zero friction loss. Boasting reliable durability and outstanding cost performance, it is widely applied in dry micro automation systems, small DC motors, precision electronics and general miniature transmission equipment.
6202-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to achieve comprehensive isolation from moisture, splash water, oil mist and corrosive fine dust. It firmly locks internal lubricating grease to prevent leakage and aging, enabling long-term maintenance-free operation, perfectly adapting to humid, dusty and mild outdoor working conditions for miniature precision devices.
6202 Bearing Material Performance
Carbon Steel: Cost-effective standard industrial material with uniform hardness and excellent anti-fatigue properties. It provides stable wear resistance and smooth high-speed rotation for conventional light-load miniature equipment, delivering optimal cost performance for mass consumer electronics and general industrial applications.
304 Stainless Steel: Universal food-grade stainless steel with superior anti-oxidation and rust resistance. It prevents surface corrosion and precision degradation in humid and open environments, ideal for food processing mini devices, light industry and daily precision miniature machinery.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. It withstands mild chemical erosion and coastal high-humidity conditions, suitable for sanitary miniature equipment, marine micro devices and light chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It features reliable wear and impact resistance, ensuring stable dimensional accuracy for long-cycle operating miniature precision parts.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It maintains precise and stable operation under slight wear and complex corrosive environments, customized for high-end electronic and industrial precision miniature equipment.
Core Advantages And Industrial Applications
The 6202 deep groove ball bearing features an ultra-compact lightweight structure, upgraded load capacity, ultra-low noise and stable high-speed performance. Three diversified sealing structures and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion miniature application scenarios. It is extensively utilized in micro motors, precision instruments, consumer electronics, intelligent equipment transmission parts, small household appliances, miniature medical devices, automated precision accessories and food processing micro equipment, providing durable, low-maintenance and high-efficiency precision rotation solutions for modern light-load miniature mechanical systems.
