62307 Deep Groove Ball Bearing | Open, ZZ, 2RS Thick-Wall Industrial Bearings
The 62307 deep groove ball bearing is a high-performance thick-wall heavy-duty model in the 62300 series, upgraded from the 62306 with larger rolling elements, widened raceways and enhanced structural rigidity. It delivers upgraded radial and axial load capacity, superior impact resistance and stable low-noise high-speed operation, ideal for long-cycle, high-intensity continuous industrial operation under heavy fluctuating loads. This versatile single-row ball bearing is a core component for medium and heavy industrial rotating and transmission equipment. It comes in three mainstream configurations: 62307 open type, 62307ZZ double metal shield type and 62307-2RS double rubber sealed type, with multiple material options to adapt to standard and harsh working environments.
62307 Open / ZZ / 2RS Structural Features
62307 Open Type: Featuring a fully open unshielded structure, this base version provides unobstructed heat dissipation and smooth internal grease circulation. It supports fast lubricant replacement and simple daily maintenance with zero extra rotational friction. Suited for clean, dry indoor workshops and fully enclosed mechanical systems, it maintains precise, stable operation for long-term cyclic working conditions with regular maintenance schedules.
62307ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this professional dust-proof bearing effectively isolates dry dust, fine debris and floating industrial particles. The non-contact design preserves original high-speed stability and low running resistance, ensuring consistent rotational accuracy during continuous operation. With excellent durability and cost performance, it is widely used for dry production lines, industrial automation and indoor heavy-load transmission machinery.
62307-2RS Double Rubber Seals: Adopting double-sided contact rubber sealing rings, this fully sealed model achieves all-round protection against moisture, splash water, oil stains and corrosive fine dust. It effectively locks internal lubricating grease to avoid leakage and contamination, realizing long-term maintenance-free operation. It perfectly adapts to harsh scenarios including outdoor exposure, high humidity, dusty workshops and variable industrial environments.
62307 Bearing Material Performance Introduction
Carbon Steel: The standard mass-production material for conventional 62307 bearings. It features uniform hardness, outstanding wear resistance and strong anti-fatigue performance under heavy cyclic loads. With stable mechanical properties and low manufacturing cost, it offers optimal cost performance for general industrial machinery and ordinary electromechanical equipment.
304 Stainless Steel: Food-grade anti-oxidation stainless steel with excellent atmospheric rust and corrosion resistance. It prevents surface oxidation and precision attenuation in humid and open environments, retaining stable dimensional accuracy and flexible rotation. It is ideal for light industrial equipment, outdoor electromechanical devices and standard food processing machinery.
316 Stainless Steel: Premium marine-grade corrosion-resistant material. Compared with 304 stainless steel, it boasts stronger acid, alkali and salt spray resistance, tolerating mild chemical corrosion and coastal high-humidity environments. It is specially customized for chemical transmission equipment, marine auxiliary machinery and high-standard sanitary production systems.
Core Advantages And Industrial Applications
The 62307 deep groove ball bearing features a reinforced thick-wall structure, upgraded heavy-load bearing capacity and ultra-stable low-noise operation. Three structural types and three industrial-grade materials fully cover economical, anti-rust and anti-corrosion application scenarios. It is extensively applied in heavy-duty industrial fans, high-flow water pumps, large-scale packaging machinery, automated production lines, outdoor engineering equipment, food processing devices and light chemical transmission systems, providing durable, low-maintenance and high-efficiency precision rotation solutions for medium and heavy industrial mechanical assemblies.
