696 Deep Groove Ball Bearing | Open, ZZ, 2RS Micro Precision Bearings
The 696 deep groove ball bearing is a high-performance miniature ultra-thin precision component in the 6900 series, featuring an optimized compact cross-section and upgraded reinforced raceway structure for improved rigidity and stable load capacity. Designed exclusively for micro-space and miniaturized mechanical installation scenarios, this single-row tiny bearing delivers outstanding rotational accuracy, low-friction operation and reliable anti-fatigue performance under light and medium micro loads. It supports long-term ultra-quiet, continuous high-speed operation, serving as an essential core rotary component for compact precision electronics and micro electromechanical systems. The 696 series offers three standard industrial configurations: open type, 696ZZ double metal shield type and 696-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, wear-resistant and corrosive complex working environments.
696 Open / ZZ / 2RS Structural Features
696 Open Type: The unsealed open structure features unobstructed air circulation and efficient heat dissipation, effectively eliminating thermal accumulation during prolonged high-speed micro operation. It enables convenient grease replenishment and tool-free daily maintenance without generating extra rotational resistance. Perfect for clean, dry indoor workshops and fully enclosed micro-precision devices, it maintains stable running accuracy and consistent performance during long-cycle light-load operation.
696ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this professional dust-proof micro bearing effectively blocks fine dry dust, floating micro particles and tiny industrial debris. The non-contact protective design preserves original high-speed precision and rotational smoothness with minimal friction loss. Boasting reliable long-term durability and superior cost performance, 696ZZ bearings are widely applied in dry miniature high-speed motors, consumer electronics, smart precision devices and compact micro-transmission systems.
696-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to comprehensively isolate moisture, water splashes, oil mist and corrosive fine dust. It tightly locks internal micro lubricating grease to prevent leakage, oxidation and aging, realizing long-term maintenance-free operation. It perfectly adapts to humid, dusty and mildly harsh working conditions for portable, outdoor and industrial micro-precision electromechanical equipment.
696 Bearing Material Performance
Carbon Steel: High cost-performance standard industrial material with uniform hardness and stable anti-fatigue properties. It delivers reliable wear resistance and smooth high-speed rotation for conventional micro-precision equipment, providing optimal cost efficiency for mass electronic products and small industrial batch applications.
304 Stainless Steel: Food-grade stainless steel with excellent oxidation and rust resistance. It prevents micro corrosion and precision degradation in humid open environments, ideal for miniature food processing equipment, sanitary micro-devices and daily precision gadgets.
316 Stainless Steel: 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 micro-precision parts, sanitary instruments and chemical miniature equipment.
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 micro dimensional stability during long-term continuous high-speed 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 miniature ultra-thin precision industrial and electronic equipment.
Core Advantages And Industrial Applications
The 696 deep groove ball bearing integrates an ultra-compact micro-size structure, lightweight ultra-thin design, ultra-low noise and durable high-speed precision performance. Three diversified sealing structures and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion micro-precision application scenarios. It is extensively used in miniature precision motors, smart wearable devices, consumer electronics, small household appliances, micro medical devices, automated micro-components and light-duty sanitary machinery, providing compact, low-maintenance and high-efficiency precision rotation solutions for modern micro-space limited miniaturized mechanical systems.
