62204 Deep Groove Ball Bearings

62204 Deep Groove Ball Bearing | Open, ZZ, 2RS High Load Bearings

The 62204 deep groove ball bearing is a high-performance thickened model in the 622 series, designed with widened raceways and enlarged rolling elements to deliver superior radial load capacity and rigid structural stability. Optimized for compact industrial mechanical systems requiring high-speed steady rotation and heavy-load endurance, this single-row bearing features low-friction operation, excellent anti-fatigue performance and ultra-quiet cyclic movement. It supports long-term continuous operation under medium-heavy loads, perfectly fitting space-limited precision electromechanical and automation equipment. The 62204 series provides three standard industrial specifications: open type, 62204ZZ double metal shield type and 62204-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, high-wear and corrosive complex working environments.

62204 Open / ZZ / 2RS Structural Features

62204 Open Type: The unsealed open structure ensures unobstructed air circulation and efficient heat dissipation, effectively preventing thermal accumulation during prolonged high-speed and heavy-load operation. It enables tool-free grease replenishment and simple routine maintenance without generating extra rotational resistance. Suitable for clean, dry indoor workshops and fully enclosed precision machinery, it maintains stable running accuracy and consistent performance during long-cycle heavy-duty operation.

62204ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this professional dust-proof bearing effectively blocks fine dry dust, floating micro particles and industrial debris. The non-contact protective design retains original high-speed precision and rotational smoothness with minimal friction loss. Featuring long service durability and excellent cost performance, 62204ZZ bearings are widely applied in industrial high-speed motors, precision automation components, power transmission devices and dry mechanical operation systems.

62204-2RS 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 lubricating grease to prevent leakage, oxidation and aging, realizing long-term maintenance-free operation. It stably adapts to humid, dusty and mildly harsh working conditions for outdoor, portable and industrial heavy-duty precision electromechanical equipment.

62204 Bearing Material Performance

Carbon Steel: High cost-performance standard industrial material with uniform hardness and stable anti-fatigue properties. It delivers dependable wear resistance and smooth high-speed rotation for conventional precision machinery, providing optimal cost efficiency for mass industrial and electronic batch applications.

304 Stainless Steel: Food-grade stainless steel with outstanding oxidation and rust resistance. It prevents micro corrosion and precision degradation in humid and open environments, ideal for food processing machinery, sanitary equipment and daily precision electromechanical devices.

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 precision parts, sanitary instruments and chemical processing 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 dimensional stability during long-term continuous high-load 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 conditions, customized for high-end industrial precision mechanical systems.
