62308 Deep Groove Ball Bearing | Open, ZZ, 2RS Heavy-Duty Bearings
The 62308 deep groove ball bearing is a top-tier thick-wall heavy-duty bearing in the 62300 series, optimized with enlarged bore size, upgraded rolling elements and reinforced raceway structure compared to the 62307 model. It delivers superior radial and axial load capacity, exceptional impact resistance and stable low-noise high-speed performance, perfectly suited for high-intensity, long-cycle continuous operation under heavy and fluctuating industrial loads. As a core universal transmission component, the 62308 bearing supports diverse complex working conditions and is available in three mainstream configurations: open type, 62308ZZ double metal shield type and 62308-2RS double rubber sealed type, paired with multiple industrial-grade materials for customized applications.
62308 Open / ZZ / 2RS Structural Features
62308 Open Type: This basic unsealed, unshielded structure features unobstructed heat dissipation and free internal grease circulation. It enables fast lubricant replacement and effortless routine maintenance with zero extra rotational friction. Designed for clean, dry indoor workshops and fully enclosed mechanical systems, it maintains high-precision stable operation for long-cycle equipment with standardized maintenance schedules.
62308ZZ Double Metal Shields: Fitted with dual-sided non-contact steel shields, this dust-proof variant effectively isolates dry industrial dust, fine particles and floating debris. The non-contact design preserves original high-speed stability and low running resistance, ensuring consistent rotational accuracy during continuous operation. Boasting high durability and outstanding cost performance, it is the ideal choice for dry production lines, industrial automation and indoor heavy-load transmission machinery.
62308-2RS Double Rubber Seals: Equipped with double-sided contact rubber sealing rings, this fully sealed model provides comprehensive all-round protection against moisture, splash water, oil contamination and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage and deterioration, realizing long-term maintenance-free operation. It reliably adapts to harsh environments including outdoor exposure, high humidity, dusty workshops and variable industrial working scenarios.
62308 Bearing Material Performance
Carbon Steel: The standard mass-production material for conventional 62308 bearings. It features uniform hardness, excellent wear resistance and strong anti-fatigue performance under heavy cyclic loads. With stable mechanical properties and low manufacturing costs, it delivers excellent cost performance for general industrial machinery and ordinary electromechanical equipment.
304 Stainless Steel: Food-grade anti-oxidation stainless steel with reliable atmospheric rust and corrosion resistance. It effectively avoids surface oxidation and precision degradation in humid and open environments, retaining stable dimensional accuracy and flexible rotation. It is widely applied in light industrial facilities, outdoor electromechanical devices and standard food processing machinery.
316 Stainless Steel: Premium marine-grade corrosion-resistant material. It features enhanced acid, alkali and salt spray resistance compared to 304 stainless steel, tolerating mild chemical corrosion and coastal high-humidity environments. It is specially customized for chemical transmission systems, marine auxiliary equipment and high-standard sanitary production machinery.
Core Advantages And Industrial Applications
The 62308 deep groove ball bearing adopts an upgraded thick-wall reinforced structure, featuring ultra-strong heavy-load capacity, excellent impact tolerance and stable low-noise operation. Three structural designs and three material grades fully cover economical, anti-rust and anti-corrosion working scenarios. Widely used in heavy-duty industrial fans, high-flow water pumps, large packaging machinery, automated production lines, outdoor engineering equipment, food processing devices and light chemical transmission systems, it provides durable, low-maintenance and high-efficiency precision rotation solutions for medium and heavy industrial mechanical assemblies.
