62312 Deep Groove Ball Bearing | Open, ZZ, 2RS Thick-Wall Bearings
The 62312 deep groove ball bearing is a large-bore, heavy-duty thick-wall component in the 62300 series, featuring optimized enlarged rolling elements and reinforced raceway structure compared to the 62311 model. It delivers boosted radial and axial load capacity, stronger impact resistance and exceptional running stability, supporting low-noise, long-cycle high-speed operation under heavy and fluctuating industrial loads. Designed for critical medium and heavy transmission machinery, the 62312 bearing is available in three core configurations: open type, 62312ZZ double metal shield type and 62312-2RS double rubber sealed type. With five versatile material grades, it perfectly adapts to general, sanitary, wear-intensive and corrosive working environments.
62312 Open / ZZ / 2RS Structural Features
62312 Open Type: This basic unsealed open structure offers unobstructed heat dissipation and smooth grease circulation. It allows quick lubricant refilling and simple routine maintenance without additional rotational friction. Ideal for clean, dry indoor facilities and fully enclosed mechanical systems, it sustains stable high-precision operation for equipment with regular maintenance cycles.
62312ZZ Double Metal Shields: Fitted with dual-sided non-contact steel shields, this dust-proof version effectively blocks dry dust, fine particles and floating workshop debris. The non-contact design preserves original high-speed performance and rotational accuracy during continuous operation. Offering excellent cost performance and durability, it is widely used for dry production lines, industrial automation and indoor heavy-load transmission equipment.
62312-2RS Double Rubber Seals: Equipped 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 lubrication to prevent leakage and contamination, achieving long-term maintenance-free operation, making it ideal for outdoor, humid, dusty and harsh industrial working conditions.
62312 Bearing Material Specifications
Carbon Steel: Standard industrial grade with uniform hardness, outstanding wear resistance and anti-fatigue performance. It stably withstands heavy cyclic loads with low production cost, serving as the most cost-effective option for general industrial and commercial machinery.
304 Stainless Steel: Popular anti-rust grade with superior atmospheric oxidation resistance. It resists surface rust and precision degradation in humid and open environments, suitable for light industry, outdoor equipment and standard food processing machinery.
316 Stainless Steel: Marine-grade corrosion-resistant material with excellent acid, alkali and salt spray tolerance. It handles mild chemical corrosion and coastal humid conditions, ideal for chemical transmission, marine equipment and high-standard sanitary production lines.
420 Stainless Steel: Martensitic high-toughness stainless steel that balances moderate corrosion resistance and high hardness. It delivers reliable wear resistance under impact and medium-corrosion conditions, perfect for precision industrial mechanical components.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion and load resistance. It maintains precise stable operation under heavy loads and complex corrosive environments, tailored for high-end precision industrial equipment.
Core Advantages And Industrial Applications
The 62312 deep groove ball bearing features a reinforced thick-wall structure, superior heavy-load capacity and consistent low-noise high-speed performance. Diversified sealing designs and five material options fully cover economical, anti-rust, wear-resistant and anti-corrosion application scenarios. It is extensively applied in large industrial fans, high-power water pumps, heavy-duty packaging machinery, automated production lines, outdoor engineering devices, food processing systems and light chemical transmission equipment, providing stable, low-maintenance and high-precision rotation solutions for heavy industrial mechanical assemblies.
