6703 Deep Groove Ball Bearing | Open, ZZ, 2RS Thin-Wall Precision Bearings
The 6703 deep groove ball bearing is a professional thin-wall precision model in the 6700 series, featuring a slim lightweight structure and optimized raceway design for high-precision, low-friction operation. Different from standard thick-wall bearings, this single-row thin-wall bearing saves installation space while maintaining excellent dimensional stability and anti-fatigue performance, supporting long-term ultra-quiet, high-speed operation under light and medium loads. As a core compact rotary component for slim mechanical systems, the 6703 series includes three mainstream configurations: open type, 6703ZZ double metal shield type and 6703-2RS double rubber sealed type. Five industrial-grade material options fully meet economical, sanitary, wear-resistant and anti-corrosion demands for precision and space-limited industrial scenarios.
6703 Open / ZZ / 2RS Structural Features
6703 Open Type: The unsealed open structure delivers unobstructed air circulation and efficient heat dissipation, avoiding heat accumulation during continuous high-speed operation. It allows convenient grease replacement and daily maintenance without increasing extra rotational resistance. Ideal for clean, dry indoor environments and fully enclosed slim precision machinery, it maintains stable running accuracy and consistent performance in long-cycle light and medium-load operation.
6703ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof precision bearing effectively blocks fine dry dust, tiny floating particles and micro workshop debris. The non-contact design retains original high-speed precision and rotational smoothness with minimal friction loss. With reliable durability and outstanding cost performance, 6703ZZ bearings are widely applied in dry precision automation equipment, slim micro motors, electronic precision devices and compact transmission systems.
6703-2RS 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 and aging, realizing long-term maintenance-free operation. It perfectly adapts to humid, dusty and mild outdoor working conditions for compact precision electromechanical equipment.
6703 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 and general industrial 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 devices and daily precision slim machinery.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. 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.
