6706 Deep Groove Ball Bearing | Open, ZZ, 2RS Thin-Wall Precision Bearings
The 6706 deep groove ball bearing is a high-stability thin-wall precision component belonging to the 6700 series, featuring optimized raceway geometry and upgraded rolling element configuration to enhance load capacity and structural rigidity. Designed with an ultra-slim, lightweight profile, this single-row deep groove ball bearing solves space installation limitations for compact precision mechanical systems. It delivers outstanding anti-fatigue performance, low-friction rotation and consistent dimensional stability, supporting long-term low-noise, high-speed operation under light and medium cyclic loads. The 6706 series offers three standard industrial versions: open type, 6706ZZ double metal shield type and 6706-2RS double rubber sealed type, with five industrial-grade materials to adapt to economic, sanitary, wear-resistant and corrosive working environments for diverse precision applications.
6706 Open / ZZ / 2RS Structural Features
6706 Open Type: The unsealed open structure ensures unobstructed airflow and efficient heat dissipation, effectively preventing heat accumulation during continuous high-speed operation. It supports quick grease replacement and simple daily maintenance without generating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed slim precision machinery, it maintains stable running accuracy and reliable performance during long-cycle light and medium-load operation.
6706ZZ 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 preserves original high-speed precision and rotational smoothness with minimal friction loss. Featuring stable durability and excellent cost performance, 6706ZZ bearings are widely used in dry precision automation systems, slim drive motors, high-end electronic devices and compact transmission equipment.
6706-2RS Double Rubber Seals: This fully sealed model adopts double-sided contact rubber seals to fully isolate moisture, splash water, oil mist and corrosive fine dust. It firmly 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 compact precision electromechanical devices.
6706 Bearing Material Performance
Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. It provides reliable wear resistance and smooth high-speed operation for conventional precision equipment, ideal for mass electronic products and general industrial cost-effective applications.
304 Stainless Steel: Food-grade stainless steel with excellent oxidation and rust resistance. It avoids surface corrosion and precision attenuation in humid environments, suitable for food processing micro equipment, sanitary machinery and daily precision slim devices.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong resistance to acid, alkali and salt spray. It withstands mild chemical erosion and coastal high humidity, perfect for marine precision parts, sanitary processing equipment and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel with balanced corrosion resistance and high surface hardness. It delivers stable wear and impact resistance, maintaining precise dimensional accuracy during long-term continuous precision operation.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance and structural stability. It sustains accurate and stable operation under severe wear and complex corrosive environments, tailored for high-end industrial and electronic slim precision equipment.
