6705 Deep Groove Ball Bearing | Open, ZZ, 2RS Thin-Wall Precision Bearings
The 6705 deep groove ball bearing is a high-performance thin-wall precision bearing in the 6700 series, featuring optimized enlarged rolling elements and upgraded raceway design for improved load capacity and structural stability. This single-row thin-wall bearing adopts an ultra-slim, lightweight structure, perfectly catering to space-limited compact precision mechanical systems. It maintains excellent anti-fatigue rigidity and low-friction characteristics, supporting long-term ultra-quiet, stable high-speed operation under light and medium cyclic loads. As a core rotary component for slim electromechanical devices, the 6705 series includes three standard configurations: open type, 6705ZZ double metal shield type and 6705-2RS double rubber sealed type. Five industrial-grade material options fully adapt to economical, sanitary, wear-resistant and corrosive working environments for diversified precision industrial applications.
6705 Open / ZZ / 2RS Structural Features
6705 Open Type: The unsealed open structure delivers unobstructed air circulation and efficient heat dissipation, effectively eliminating thermal accumulation during continuous high-speed operation. It allows convenient grease replacement and daily routine maintenance without generating extra rotational resistance. Designed for clean, dry indoor workshops and fully enclosed slim precision machinery, it sustains stable running accuracy and consistent performance during long-cycle light and medium-load operation.
6705ZZ 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 design retains original high-speed precision and rotational smoothness with minimal friction loss. Boasting reliable durability and outstanding cost performance, 6705ZZ bearings are widely used in dry precision automation equipment, slim drive motors, precision electronic devices and compact transmission systems.
6705-2RS 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 mild outdoor working conditions for compact precision electromechanical equipment.
6705 Bearing Material Performance
Carbon Steel: Cost-effective standard industrial material with uniform hardness and stable anti-fatigue properties. It provides reliable wear resistance and smooth high-speed rotation for conventional precision equipment, delivering excellent cost performance for mass electronic products and general industrial 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, ideal for food processing micro equipment, sanitary machinery and daily slim precision devices.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong tolerance to acid, alkali and salt spray. It withstands mild chemical erosion and coastal high humidity, suitable for marine precision accessories, 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, ensuring consistent dimensional accuracy during long-cycle continuous precision operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It maintains precise and stable operation under complex wear and corrosive environments, customized for high-end slim precision industrial and electronic equipment.
