6816 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6816 deep groove ball bearing is a large-bore ultra-thin heavy-duty precision bearing in the 6800 series, featuring thickened raceway grooves and optimized oversized rolling elements for enhanced structural rigidity and maximum heavy-load capacity. Retaining the series’ ultra-slim space-saving design, this single-row thin-wall bearing solves strict space-constrained installation requirements for large compact precision machinery without sacrificing operational stability. It delivers consistent low-friction rotation, reliable anti-fatigue performance and precise dimensional stability, supporting long-term ultra-quiet, high-speed cyclic operation under continuous heavy loads. The 6816 series provides three standard industrial configurations: open type, 6816ZZ double metal shield type and 6816-2RS double rubber sealed type, with five industrial-grade material options to fit economical, sanitary, wear-resistant and corrosive industrial working environments.
6816 Open / ZZ / 2RS Structural Features
6816 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively preventing thermal accumulation during prolonged high-speed operation. It supports quick grease replacement and hassle-free routine maintenance with zero extra rotational resistance. Designed for clean, dry indoor workshops and fully enclosed large slim precision equipment, it maintains stable running accuracy and steady performance during long-cycle heavy-load operation.
6816ZZ 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 structure preserves original high-speed precision and rotational smoothness with minimal friction loss. Featuring outstanding durability and cost performance, 6816ZZ bearings are widely used in dry precision automation systems, large slim high-power motors, precision electronic devices and compact heavy-duty transmission machinery.
6816-2RS 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.
6816 Bearing Material Performance
Carbon Steel: High cost-performance industrial standard 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, offering excellent cost efficiency for mass industrial and electronic batch applications.
304 Stainless Steel: Food-grade stainless steel with superior rust and oxidation resistance. It prevents surface corrosion and precision degradation in humid environments, ideal for food processing machinery, sanitary equipment and slim precision devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong resistance to acid, alkali and salt spray. It withstands chemical erosion and coastal high humidity, suitable 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 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. It sustains precise, stable operation under severe wear and corrosive conditions, customized for high-end ultra-thin precision industrial equipment.
Core Advantages And Industrial Applications
The 6816 deep groove ball bearing features an ultra-thin lightweight structure, space-saving installation, upgraded heavy-load capacity, ultra-low noise and durable high-speed precision performance. Three sealing types and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion application scenarios. It is extensively applied 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.
