695 Deep Groove Ball Bearing | Open, ZZ, 2RS Micro Precision Bearings
The 695 deep groove ball bearing is a miniature ultra-thin precision component in the 6900 series, designed with a compact slim cross-section and optimized low-friction raceway structure. Engineered for micro-space installation scenarios, this tiny single-row bearing delivers stable rotational accuracy and reliable anti-fatigue performance under light and micro loads. It supports long-term ultra-quiet, high-speed continuous operation, making it a core rotary part for miniaturized electronic and precision mechanical equipment. The 695 series covers three mainstream industrial configurations: open type, 695ZZ double metal shield type and 695-2RS double rubber sealed type. Five industrial-grade material options fully adapt to economical, sanitary, wear-resistant and corrosive working environments for diversified micro-precision applications.
695 Open / ZZ / 2RS Structural Features
695 Open Type: The unsealed open structure ensures unobstructed air circulation and rapid heat dissipation, effectively preventing thermal accumulation during prolonged high-speed micro-operation. It allows simple grease replenishment and tool-free daily maintenance without increasing extra rotational resistance. Ideal for clean, dry indoor environments and fully enclosed micro-precision devices, it maintains consistent running accuracy and stable performance during long-cycle light-load operation.
695ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this miniature dust-proof bearing effectively blocks fine dry dust, micro floating particles and tiny workshop debris. The non-contact design retains original high-speed precision and rotational smoothness with minimal friction loss. Featuring stable durability and excellent cost performance, 695ZZ bearings are widely applied in dry miniature motors, consumer electronics, precision smart devices and compact micro-transmission systems.
695-2RS Double Rubber Seals: This fully sealed micro bearing adopts double-sided contact rubber seals to comprehensively isolate moisture, tiny 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 and outdoor micro-precision electromechanical equipment.
695 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 micro-precision equipment, delivering optimal cost efficiency for mass electronic and small industrial batch applications.
304 Stainless Steel: Food-grade stainless steel with superior oxidation and rust resistance. It prevents micro corrosion and precision degradation in humid environments, suitable for miniature food processing equipment, sanitary micro-devices and daily precision gadgets.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. It withstands mild chemical erosion and coastal high humidity, ideal 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.
