6207 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Bearings
The 6207 deep groove ball bearing is a high-performance medium-sized model in the 6200 series, upgraded from the 6206 variant with optimized rolling element layout and thickened raceway structure. This single-row deep groove ball bearing delivers enhanced radial and axial load capacity, improved structural rigidity and superior anti-fatigue stability, supporting stable low-friction, low-noise high-speed operation under continuous medium-heavy cyclic loads. Balancing compact dimensions and robust load-bearing performance, it serves as a core rotary component for medium-duty industrial electromechanical and automated equipment. The 6207 series features three standard configurations: open type, 6207ZZ double metal shield type and 6207-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, high-wear and corrosive complex industrial environments.
6207 Open / ZZ / 2RS Structural Features
6207 Open Type: The unsealed open structure enables unobstructed air convection and efficient heat dissipation during long-term high-speed operation. It allows convenient grease replacement and routine maintenance without generating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision machinery, it maintains stable running accuracy and consistent performance during long-cycle medium-heavy load operation.
6207ZZ 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 stability and rotational precision with minimal friction loss. Featuring reliable durability and excellent cost performance, it is widely applied in dry automated production lines, industrial medium-sized motors, precision electronic devices and general transmission machinery.
6207-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals for comprehensive isolation from moisture, splash water, oil mist and corrosive dust. It tightly locks internal lubricating grease to prevent leakage and aging, realizing long-term maintenance-free operation, perfectly adapting to humid, dusty and mild outdoor working conditions for medium-heavy precision mechanical equipment.
6207 Bearing Material Performance
Carbon Steel: Standard cost-effective industrial material with uniform hardness and excellent anti-fatigue properties. It provides stable wear resistance and smooth high-speed rotation for medium-heavy load mechanical equipment, delivering optimal cost performance for mass civilian and general industrial applications.
304 Stainless Steel: Universal food-grade stainless steel with superior anti-oxidation and rust resistance. It avoids surface corrosion and precision degradation in humid and open environments, suitable for food processing machinery, light industry and daily precision equipment.
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, ideal for sanitary processing equipment, marine auxiliary devices and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It features excellent wear and impact resistance, ensuring stable dimensional accuracy for long-cycle medium-heavy load 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 heavy wear and complex corrosive environments, customized for high-end industrial and precision mechanical equipment.
Core Advantages And Industrial Applications
The 6207 deep groove ball bearing boasts outstanding medium-heavy load capacity, high structural stability, ultra-low noise and reliable long-term high-speed performance. Three diversified sealing structures and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion industrial scenarios. It is extensively used in industrial drive motors, precision instruments, household appliances, automated transmission systems, medical devices, food processing machinery and outdoor light industrial facilities, providing durable, low-maintenance and high-efficiency precision rotation solutions for modern medium-heavy duty mechanical systems.
