62311 Deep Groove Ball Bearing | Open, ZZ, 2RS Thick Wall Bearings
The 62311 deep groove ball bearing is a large-bore, thick-wall heavy-duty bearing in the 62300 series, featuring upgraded internal structure, larger rolling elements and reinforced raceway design compared to the 62310 model. It delivers improved radial and axial load capacity, stronger impact resistance and superior operational stability, supporting continuous low-noise, high-speed rotation under heavy, fluctuating industrial loads. Engineered for medium and heavy-duty transmission equipment, the 62311 bearing is offered in three core configurations: open type, 62311ZZ double metal shield type and 62311-2RS double rubber sealed type. With five professional material options, it adapts to economic, wear-resistant, sanitary and highly corrosive working conditions.
62311 Open / ZZ / 2RS Structural Features
62311 Open Type: This basic unsealed structure features unobstructed heat dissipation and smooth internal grease circulation. It supports fast lubricant replacement and hassle-free routine maintenance with zero extra rotational resistance. Suited for clean, dry indoor workshops and fully enclosed mechanical systems, it maintains consistent high-precision operation for equipment with regular maintenance schedules.
62311ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof variant effectively blocks dry dust, fine particles and floating industrial debris. The non-contact design preserves original high-speed performance and stable rotational accuracy during long-cycle continuous operation. It serves as a high-cost-performance solution for dry production lines, industrial automation and indoor heavy-load machinery.
62311-2RS Double Rubber Seals: Designed with double-sided contact rubber seals, this fully sealed model provides all-round protection against moisture, splash water, oil contamination and corrosive dust. It locks internal lubricating grease to prevent leakage and deterioration, realizing long-term maintenance-free operation, ideal for outdoor, humid, dusty and harsh industrial environments.
62311 Bearing Material Performance
Carbon Steel: Standard industrial bulk material with uniform hardness, excellent wear resistance and anti-fatigue properties. It stably handles medium and heavy cyclic loads at low cost, perfect for general industrial machinery and conventional transmission equipment.
304 Stainless Steel: Universal anti-rust stainless steel with outstanding atmospheric oxidation resistance. It prevents surface rust and precision decay in humid open environments, suitable for light industry, outdoor machinery and standard food processing equipment.
316 Stainless Steel: Premium marine-grade material with excellent acid, alkali and salt spray resistance. It withstands mild chemical corrosion and coastal high-humidity conditions, ideal for chemical, marine and high-standard sanitary production equipment.
420 Stainless Steel: High-toughness martensitic stainless steel balancing corrosion resistance and extreme hardness. It delivers superior wear resistance under medium corrosion and impact loads, applicable for precision industrial mechanical parts.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier load stability and abrasion resistance. It maintains precise operation under heavy loads and complex corrosive environments, customized for high-end precision industrial equipment.
Core Advantages And Industrial Applications
The 62311 deep groove ball bearing features a thickened reinforced structure, upgraded heavy-load capacity and stable low-noise high-speed performance. Multiple sealing structures and five diversified materials fully cover economic, anti-rust, wear-resistant and anti-corrosion scenarios. It is widely used in large industrial fans, high-power 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 rotation solutions for heavy-duty industrial mechanical assemblies.
