6716 Deep Groove Ball Bearing | Open, ZZ, 2RS Thin-Wall Precision Bearings
The 6716 deep groove ball bearing is a maximum bore thin-wall heavy-duty precision bearing in the 6700 series, featuring fully thickened raceway grooves and enlarged reinforced rolling elements for boosted structural rigidity and superior medium-heavy load capacity. Retaining the classic ultra-slim, lightweight thin-wall structure, this single-row bearing solves extreme space-limited installation demands for large compact precision mechanical systems. It delivers stable low-friction rotation, excellent anti-fatigue performance and consistent dimensional accuracy, supporting long-term low-noise, high-speed continuous operation under heavy cyclic loads. The 6716 series covers three mainstream industrial sealing configurations: open type, 6716ZZ double metal shield type and 6716-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, high-wear and corrosive complex industrial environments.
6716 Open / ZZ / 2RS Structural Features
6716 Open Type: The unsealed open structure achieves unobstructed air circulation and efficient heat dissipation, effectively eliminating thermal accumulation during long-duration high-speed operation. It supports quick grease replenishment and hassle-free routine maintenance without increasing extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed large slim precision machinery, it maintains stable running accuracy and steady performance during long-cycle heavy-load operation.
6716ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this industrial 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. Boasting reliable long-term durability and outstanding cost performance, 6716ZZ bearings are widely used in dry precision automation equipment, large slim high-power motors, precision electronic systems and compact heavy-duty transmission machinery.
6716-2RS Double Rubber Seals: This fully sealed model 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 outdoor working conditions for large compact high-precision electromechanical devices.
6716 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 heavy-load precision equipment, delivering optimal cost efficiency for mass industrial and electronic batch applications.
304 Stainless Steel: Food-grade stainless steel with excellent oxidation and rust resistance. It prevents surface corrosion and precision degradation in humid and open environments, suitable for food processing equipment, sanitary machinery and daily slim precision devices.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. It withstands 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 complex corrosive environments, customized for high-end industrial and electronic slim precision equipment.
Core Advantages And Industrial Applications
The 6716 deep groove ball bearing features an ultra-thin space-saving structure, lightweight design, maximum heavy-load capacity, ultra-low noise and durable high-speed stability. 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 applied in large slim high-power precision motors, industrial automation transmission systems, miniature testing instruments, consumer electronics, smart equipment components, miniature medical devices and food processing machinery, providing compact, low-maintenance and high-efficiency precision rotation solutions for modern space-limited heavy-load precision mechanical systems.
