6810 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6810 deep groove ball bearing is a large-bore ultra-thin precision bearing in the 6800 series, featuring reinforced thickened raceways and optimized rolling element configuration to enhance structural rigidity and medium-heavy load capacity. Maintaining the series’ signature ultra-slim, space-saving and lightweight design, this single-row thin-wall bearing solves strict space-constrained installation needs for large miniaturized precision machinery. It delivers stable low-friction rotation, superior anti-fatigue performance and consistent dimensional accuracy, supporting long-term ultra-quiet, high-speed continuous operation under steady medium-heavy cyclic loads. The 6810 series includes three mainstream industrial configurations: open type, 6810ZZ double metal shield type and 6810-2RS double rubber sealed type, with five industrial-grade materials adapting to economical, sanitary, wear-resistant and corrosive complex working environments.
6810 Open / ZZ / 2RS Structural Features
6810 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively eliminating thermal accumulation during prolonged high-speed operation. It supports convenient regular grease replacement and simple daily maintenance without generating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed large slim precision equipment, it maintains stable running accuracy and reliable performance during long-cycle medium-heavy load operation.
6810ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this high-performance dust-proof 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 outstanding long-term durability and cost performance, 6810ZZ bearings are widely applied in dry precision automation systems, large miniature high-power motors, precision electronic devices and compact heavy-duty transmission machinery.
6810-2RS 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, realizing long-term maintenance-free operation. It perfectly adapts to humid, dusty and mildly harsh workshop and outdoor conditions for large compact precision electromechanical equipment.
6810 Bearing Material Performance
Carbon Steel: High cost-performance standard industrial material with uniform hardness and stable anti-fatigue properties. It provides reliable wear resistance and smooth high-speed rotation for conventional medium-heavy load precision equipment, delivering optimal cost efficiency for mass industrial and electronic 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, suitable for food processing machinery, sanitary equipment 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, ideal 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 equipment.
Core Advantages And Industrial Applications
The 6810 deep groove ball bearing features an ultra-thin space-saving structure, lightweight design, upgraded medium-heavy 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 large miniature precision motors, industrial automation transmission systems, smart device components, consumer electronics, miniature medical devices and food processing machinery, providing compact, low-maintenance and high-efficiency precision rotation solutions for modern space-limited medium-heavy load mechanical systems.
