6807 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6807 deep groove ball bearing is a high-performance ultra-thin precision component in the 6800 series, designed with reinforced raceway grooves and optimized rolling element arrangements to boost structural rigidity and medium-load bearing capacity. Retaining the series’ signature slim, lightweight profile, this single-row bearing solves tight space installation limitations for modern miniaturized precision machinery while delivering upgraded load stability compared to smaller ultra-thin models. It supports long-term low-friction, ultra-quiet and consistent high-speed operation under light and medium cyclic loads, serving as a core rotary component for compact electromechanical and automated precision systems. The 6807 series offers three standard industrial configurations: open type, 6807ZZ double metal shield type and 6807-2RS double rubber sealed type, with five industrial-grade materials adapting to economical, sanitary, wear-resistant and corrosive working environments.
6807 Open / ZZ / 2RS Structural Features
6807 Open Type: The unsealed open structure ensures unobstructed air circulation and efficient heat dissipation, effectively preventing thermal accumulation during prolonged high-speed continuous operation. It allows convenient grease replacement and routine daily maintenance without increasing extra rotational resistance. Suitable for clean, dry indoor workshops and fully enclosed slim precision equipment, it maintains stable running accuracy and reliable performance during long-cycle light and medium-load operation.
6807ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof precision bearing effectively blocks fine dry dust, floating micro particles and workshop debris. The non-contact design preserves original high-speed precision and rotational smoothness with minimal friction loss. Featuring stable durability and excellent cost performance, 6807ZZ bearings are widely applied in dry precision automation systems, miniature high-speed motors, consumer electronics and compact precision transmission machinery.
6807-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to comprehensively isolate moisture, splash water, oil mist and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage, oxidation and aging, enabling long-term maintenance-free operation. It perfectly adapts to humid, dusty and mildly harsh workshop and outdoor conditions for portable and industrial compact precision electromechanical devices.
6807 Bearing Material Performance
Carbon Steel: Cost-effective standard industrial material with uniform hardness and stable anti-fatigue properties. It delivers reliable wear resistance and smooth high-speed rotation for conventional precision equipment, providing optimal cost efficiency for mass electronic products and general industrial batch applications.
304 Stainless Steel: Food-grade stainless steel with superior oxidation and rust resistance. It prevents surface corrosion and precision degradation in humid and open environments, ideal for food processing micro equipment, sanitary machinery and slim precision devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. It withstands mild chemical erosion and coastal high humidity, perfect for marine precision parts, sanitary processing equipment and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It features stable wear and impact resistance, maintaining accurate dimensional stability during long-term continuous precision operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It sustains precise, stable operation under severe wear and corrosive environments, customized for high-end ultra-thin precision industrial and electronic equipment.
Core Advantages And Industrial Applications
The 6807 deep groove ball bearing features an ultra-thin space-saving structure, lightweight design, enhanced medium-load capacity, ultra-low noise and durable high-speed precision performance. Three diversified sealing structures and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion precision application scenarios. It is extensively used in miniature precision motors, smart wearable devices, consumer electronics, small household appliances, miniature medical devices, automated precision accessories and light-duty food processing machinery, providing compact, low-maintenance and high-efficiency precision rotation solutions for modern miniaturized space-limited mechanical systems.
