62202 Deep Groove Ball Bearing | Open, ZZ, 2RS High Load Bearings
The 62202 deep groove ball bearing is a reinforced high-load precision bearing with a widened groove and thickened rolling body design, delivering upgraded radial load capacity and structural rigidity compared to standard miniature bearings. Optimized for compact mechanical systems requiring stable high-speed operation and strong load-bearing performance, this single-row deep groove ball bearing features excellent anti-fatigue stability and ultra-low friction rotation. It supports long-term continuous ultra-quiet operation under medium and heavy cyclic loads, ideal for space-limited precision electromechanical equipment. The 62202 series offers three mainstream industrial configurations: open type, 62202ZZ double metal shield type and 62202-2RS double rubber sealed type, with five industrial-grade material options to adapt to economic, sanitary, high-wear and corrosive working environments.
62202 Open / ZZ / 2RS Structural Features
62202 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively eliminating heat accumulation during prolonged high-speed and high-load operation. It allows tool-free grease replacement and simple daily maintenance without increasing 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-load operation.
62202ZZ 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 preserves original high-speed precision and rotational smoothness with minimal friction loss. Featuring long service durability and excellent cost performance, 62202ZZ bearings are widely applied in industrial high-speed micro motors, precision automation components, transmission devices and dry mechanical operation systems.
62202-2RS Double Rubber Seals: This fully sealed version adopts double-sided contact rubber seals to fully 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 stably adapts to humid, dusty and mildly harsh working conditions for outdoor, portable and industrial heavy-duty precision electromechanical equipment.
62202 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 machinery, delivering outstanding cost efficiency for mass industrial and electronic batch applications.
304 Stainless Steel: Food-grade stainless steel with superior oxidation and rust resistance. It prevents micro corrosion and precision degradation in humid and open environments, perfect for food processing equipment, sanitary machinery 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.
Core Advantages And Industrial Applications
