62212 Deep Groove Ball Bearing | Open, ZZ, 2RS High Load Bearings
The 62212 deep groove ball bearing is a heavy-duty thickened model in the standard 622 series, engineered with widened raceways and enlarged rolling elements to boost structural rigidity and maximize radial load capacity. Built for compact industrial machinery that demands stable high-speed rotation and long-term heavy-load durability, this single-row bearing delivers ultra-low friction, excellent anti-fatigue performance and consistent ultra-quiet cyclic operation. It reliably sustains continuous medium-heavy load operation, acting as a core rotary component for space-limited precision electromechanical systems and industrial automation equipment. The 62212 series includes three mainstream industrial configurations: open type, 62212ZZ double metal shield type and 62212-2RS double rubber sealed type, with five industrial-grade material options to fit economical, sanitary, high-wear and corrosive complex working environments.
62212 Open / ZZ / 2RS Structural Features
62212 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively eliminating thermal accumulation during prolonged high-speed and heavy-load operation. It supports tool-free grease replenishment and simple routine maintenance without generating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision machinery, it maintains stable running accuracy and consistent performance during long-cycle heavy-duty operation.
62212ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this premium 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 outstanding cost performance, 62212ZZ bearings are widely applied in industrial high-speed motors, precision automation components, power transmission devices and dry mechanical operation systems.
62212-2RS 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, achieving 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.
62212 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.
Core Advantages And Industrial Applications
The 62212 deep groove ball bearing features a thickened widened structure, upgraded heavy-load capacity, ultra-low noise and durable high-speed precision. Three diversified sealing structures and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion industrial application scenarios. It is extensively utilized in precision industrial motors, automated mechanical components, small processing machinery, electric power tools, micro medical devices and light-duty sanitary machinery. With reliable heavy-load stability and low-maintenance advantages, the 62212 bearing serves as a high-efficiency core rotary solution for modern compact mechanical systems with strict precision and load operation requirements.
