6806 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6806 deep groove ball bearing is a high-stability ultra-thin precision bearing in the 6800 series, featuring reinforced raceway structures and optimized rolling element layout for improved rigidity and enhanced medium-load capacity. Boasting the classic 6800-series ultra-slim lightweight design, this single-row deep groove ball bearing solves tight space installation constraints for modern miniaturized precision machinery. It delivers stable low-friction rotation, outstanding dimensional consistency and excellent anti-fatigue performance, supporting long-term ultra-quiet, high-speed operation under steady light and medium cyclic loads. The 6806 series includes three mainstream industrial configurations: open type, 6806ZZ double metal shield type and 6806-2RS double rubber sealed type, with five industrial-grade material options to accommodate economical, sanitary, wear-resistant and corrosive complex working environments.
6806 Open / ZZ / 2RS Structural Features
6806 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively eliminating thermal accumulation during prolonged continuous high-speed operation. It supports convenient regular grease replacement and hassle-free daily maintenance without generating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed slim precision equipment, it maintains stable running accuracy and consistent performance during long-cycle light and medium-load operation.
6806ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this premium dust-proof precision bearing effectively blocks fine dry dust, floating micro particles and tiny workshop debris. The non-contact protective design preserves original high-speed precision and rotational smoothness with minimal friction loss. Featuring reliable long-term durability and excellent cost performance, 6806ZZ bearings are widely applied in dry precision automation systems, miniature high-speed motors, precision consumer electronics and compact transmission machinery.
6806-2RS 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, realizing long-term maintenance-free operation. It perfectly adapts to humid, dusty and mildly harsh workshop and outdoor conditions for portable and industrial compact precision electromechanical devices.
6806 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 optimal cost efficiency 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, suitable for food processing micro equipment, sanitary machinery and slim precision devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong resistance to acid, alkali and salt spray. It withstands mild 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 corrosive environments, customized for high-end ultra-thin precision industrial and electronic equipment.
Core Advantages And Industrial Applications
