6711 Deep Groove Ball Bearing | Open, ZZ, 2RS Thin-Wall Precision Bearings
The 6711 deep groove ball bearing is a large-bore, heavy-duty thin-wall precision component in the 6700 series, designed with thickened raceways and optimized rolling element layout for enhanced structural rigidity and improved medium-heavy load capacity. Featuring a signature ultra-slim and lightweight structure, this single-row deep groove ball bearing solves space constraints in compact precision mechanical systems while delivering reliable load endurance and anti-fatigue stability. It supports long-term low-noise, low-friction high-speed rotation under continuous medium-heavy cyclic loads, making it ideal for high-precision compact electromechanical systems. The 6711 series comes with three standard industrial configurations: open type, 6711ZZ double metal shield type and 6711-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, wear-resistant and corrosive working environments.
6711 Open / ZZ / 2RS Structural Features
6711 Open Type: The unsealed open structure delivers unobstructed air circulation and efficient heat dissipation, preventing thermal accumulation during prolonged high-speed operation. It allows easy grease replenishment and routine maintenance without increasing rotational resistance. Suitable for clean, dry indoor environments and fully enclosed slim precision machinery, it maintains stable running accuracy and consistent performance during long-cycle medium-heavy load operation.
6711ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof precision bearing effectively blocks fine dust, floating micro particles and workshop debris. The non-contact design preserves original high-speed precision and rotational smoothness with minimal friction loss. With stable durability and excellent cost performance, 6711ZZ bearings are widely used in dry automated precision systems, slim high-power motors, precision electronics and compact heavy-duty transmission equipment.
6711-2RS Double Rubber Seals: This fully sealed version adopts double-sided contact rubber seals to isolate moisture, splash water, oil mist and corrosive dust. It locks internal lubricating grease firmly to prevent leakage and aging, achieving long-term maintenance-free operation. It reliably adapts to humid, dusty and mildly harsh outdoor working conditions for high-precision compact electromechanical devices.
6711 Bearing Material Performance
Carbon Steel: Cost-effective industrial standard material with stable hardness and anti-fatigue properties. It ensures smooth high-speed rotation and reliable wear resistance for conventional medium-load precision equipment, offering optimal cost efficiency for mass industrial and electronic applications.
304 Stainless Steel: Food-grade stainless steel with outstanding oxidation and rust resistance. It resists surface corrosion and precision degradation in humid environments, ideal for food processing equipment, sanitary machinery and daily slim precision devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with excellent acid, alkali and salt spray tolerance. It withstands chemical erosion and coastal high humidity, perfect for marine precision parts, sanitary processing machines and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel with balanced corrosion resistance and high hardness. It provides 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 and electronic precision equipment.
