6717 Deep Groove Ball Bearing | Open, ZZ, 2RS Thin-Wall Precision Bearings
The 6717 deep groove ball bearing is a large-bore, heavy-duty thin-wall precision bearing belonging to the 6700 series, designed with reinforced raceway grooves and upgraded rolling elements for improved structural rigidity and enhanced heavy-load capacity. Featuring a slim lightweight profile, this single-row deep groove ball bearing solves tight space installation limitations in modern compact precision machinery while maintaining exceptional anti-fatigue performance and stable dimensional consistency. It delivers low-friction, ultra-quiet and continuous high-speed rotation under long-term heavy cyclic loads, making it a reliable core component for high-precision automation and electromechanical systems. The 6717 series includes three standard industrial configurations: open type, 6717ZZ double metal shield type and 6717-2RS double rubber sealed type, with five industrial-grade material options to suit economical, sanitary, wear-resistant and corrosive working environments.
6717 Open / ZZ / 2RS Structural Features
6717 Open Type: The unsealed open structure enables unobstructed airflow and efficient heat dissipation, effectively preventing heat accumulation during prolonged high-speed operation. It supports easy grease replacement and routine maintenance without increasing rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed slim precision equipment, it maintains stable running accuracy and consistent performance under long-cycle heavy-load conditions.
6717ZZ 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 structure preserves original high-speed precision and rotational smoothness with minimal friction loss. Offering outstanding durability and cost performance, 6717ZZ bearings are widely used in dry precision automation systems, large slim high-power motors, precision electronic devices and compact heavy-duty transmission machinery.
6717-2RS Double Rubber Seals: This fully sealed version adopts double-sided contact rubber seals to fully isolate moisture, splash water, oil mist and corrosive fine dust. It firmly locks internal lubricating grease to prevent leakage, oxidation and aging, enabling long-term maintenance-free operation. It adapts perfectly to humid, dusty and mildly harsh outdoor working conditions for large-scale compact high-precision electromechanical equipment.
6717 Bearing Material Performance
Carbon Steel: Cost-effective industrial standard material with uniform hardness and stable anti-fatigue properties. It provides reliable wear resistance and smooth high-speed rotation for heavy-load precision equipment, delivering excellent cost efficiency for mass industrial and electronic applications.
304 Stainless Steel: Food-grade stainless steel with superior anti-rust and oxidation resistance. It avoids precision degradation in humid environments, ideal for food processing machinery, sanitary equipment and daily slim precision devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with excellent resistance to acid, alkali and salt spray. It withstands chemical corrosion and coastal high humidity, suitable for marine precision parts, sanitary processing machines and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel with balanced hardness and corrosion resistance. It offers stable wear and impact resistance, maintaining precise dimensional accuracy during long-term continuous operation.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance. It sustains stable and accurate operation under severe wear and corrosive conditions, tailored for high-end industrial precision equipment.
Core Advantages And Industrial Applications
The 6717 deep groove ball bearing features an ultra-thin space-saving structure, lightweight design, strong heavy-load capacity, ultra-low noise and long-term high-speed stability. Three sealing types and five material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion application scenarios. It is widely applied in large slim high-power precision motors, industrial automation transmission systems, precision testing instruments, consumer electronics, smart device components, miniature medical devices and food processing machinery, providing compact, low-maintenance and high-efficiency precision rotation solutions for space-limited heavy-duty precision mechanical systems.
