62310 Deep Groove Ball Bearing | Open, ZZ, 2RS Thick Wall Bearings
The 62310 deep groove ball bearing is a large-size, thick-wall heavy-duty model in the 62300 series, featuring enlarged rolling elements, widened raceways and enhanced structural rigidity compared to the 62309 version. Delivering excellent radial and axial load capacity and strong impact resistance, it supports stable low-noise, high-speed continuous operation under heavy and fluctuating loads. Widely used for medium-to-heavy industrial rotating and transmission equipment, the 62310 bearing is available in three mainstream structures: open type, 62310ZZ double metal shield type and 62310-2RS double rubber sealed type. With five optional industrial materials, it adapts to ordinary, humid, sanitary and corrosive working environments.
62310 Open / ZZ / 2RS Structural Features
62310 Open Type: This basic unsealed open structure provides maximum heat dissipation and smooth grease circulation. It allows quick lubrication replacement and easy routine maintenance without extra running friction. Ideal for clean, dry indoor workshops and fully enclosed mechanical systems, it ensures long-term stable and precise rotation under regular maintenance cycles.
62310ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof structure effectively blocks dry dust, fine particles and floating workshop debris. The non-contact design retains original high-speed performance and low rotational resistance, delivering consistent precision during continuous operation. It is a cost-effective solution for dry production lines, automation equipment and indoor heavy-load transmission machinery.
62310-2RS Double Rubber Seals: Designed with double-sided contact rubber seals, this fully sealed variant provides comprehensive protection against moisture, splash water, oil stains and corrosive dust. It locks internal lubricating grease to prevent leakage and contamination, enabling long-term maintenance-free operation. It is perfectly suited for outdoor, humid, dusty and harsh industrial working conditions.
62310 Bearing Material Introduction
Carbon Steel: Standard economical material with uniform hardness, reliable wear resistance and excellent anti-fatigue performance. It meets most medium and heavy-load working requirements, offering high cost performance for general industrial and commercial mechanical equipment.
304 Stainless Steel: Common anti-rust grade with outstanding atmospheric oxidation resistance. It prevents rust and precision degradation in humid and open environments, suitable for light industry, outdoor machinery and general food processing equipment.
316 Stainless Steel: Marine-grade corrosion-resistant material with superior acid, alkali and salt spray resistance. It withstands mild chemical corrosion and coastal humid environments, ideal for chemical equipment, marine machinery and high-standard sanitary production lines.
420 Stainless Steel: High-hardness martensitic stainless steel with excellent wear resistance and mechanical toughness. It balances corrosion resistance and structural strength, perfect for medium-corrosion environments requiring high rotational precision and impact resistance.
440 Stainless Steel: Ultra-high hardness stainless steel with extreme wear resistance and load stability. It maintains precise operation under heavy loads and complex corrosive conditions, widely used for high-precision and high-end industrial equipment.
Core Advantages And Industrial Applications
The 62310 deep groove ball bearing features a reinforced thick-wall structure, superior heavy-load capacity and stable low-noise high-speed performance. Multiple sealing structures and diversified material options fully cover economical, anti-rust, wear-resistant and anti-corrosion scenarios. It is extensively applied in heavy-duty industrial fans, large water pumps, heavy packaging machinery, automated production lines, outdoor engineering equipment, food processing devices and light chemical transmission systems, providing reliable, low-maintenance and high-precision rotating solutions for heavy industrial mechanical assemblies.
