6817 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6817 deep groove ball bearing is a premium large-bore ultra-thin heavy-duty model in the 6800 series, engineered with thickened raceway grooves and upgraded reinforced rolling elements to boost structural rigidity and heavy-load bearing capacity. Retaining the series’ signature ultra-slim, space-saving lightweight structure, this single-row thin-wall bearing resolves strict space-constrained installation challenges for large compact precision machinery. It delivers stable low-friction rotation, excellent anti-fatigue performance and consistent dimensional accuracy, supporting long-term ultra-quiet, high-speed cyclic operation under continuous heavy loads. The 6817 series features three mainstream industrial configurations: open type, 6817ZZ double metal shield type and 6817-2RS double rubber sealed type, with five industrial-grade materials catering to economical, sanitary, wear-resistant and corrosive complex working environments.
6817 Open / ZZ / 2RS Structural Features
6817 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 grease replacement and routine daily maintenance without 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 heavy-load operation.
6817ZZ 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 industrial 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, 6817ZZ bearings are widely applied in dry precision automation systems, large slim high-power motors, precision electronic devices and compact heavy-duty transmission machinery.
6817-2RS 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 large compact high-precision electromechanical equipment.
6817 Bearing Material Performance
Carbon Steel: High cost-performance standard industrial material with uniform hardness and stable anti-fatigue properties. It delivers reliable wear resistance and smooth high-speed rotation for conventional heavy-load precision equipment, providing 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 6817 deep groove ball bearing features an ultra-thin space-saving structure, lightweight design, enhanced 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 slim precision motors, industrial automation transmission systems, smart mechanical components, high-end consumer electronics, miniature medical devices and food processing machinery, providing compact, low-maintenance and high-efficiency precision rotation solutions for modern space-limited heavy-duty mechanical systems.
