Industrial Tapered Roller Bearings Manufacturers Heavy Duty Roller Bearing 32310

32310 Tapered Roller Bearing: Heavy Duty Performance For Industrial

Basic Parameters

• Bore diameter (d):50mm
• Outer diameter (D):110mm
• Width (T):40mm ~ 42.25mm
• Weight:Approximately 1.7~1.9kg
• Contact angle:12.95° (standard); special versions may feature increased angles (25°~29°)

Core Performance Parameters

• Dynamic load rating (Cr):173kN ~ 211kN
• Static load rating (C0r):211kN ~ 212kN
• Material:GCr15/SUJ2 high-carbon chromium bearing steel (surface hardness HRC58-62 after heat treatment)
• Precision class:P0 (standard)
• Limiting speed:4,500~6,300rpm (grease-lubricated)

Structural & Adaptability Parameters

• Structure:Separable (inner ring + roller assembly and outer ring are independent)
• Tolerance compatibility:Shaft tolerances (H7/k6); housing bore tolerances (J7)
• Standard compliance:ISO 355
• Environmental adaptability:
  • Temperature resistance:Up to 816°C (stainless steel variants)
  • Corrosion resistance:Available in stainless steel (e.g., SUS321) for corrosive environments

Application & Maintenance Parameters

• Typical application scenarios:
  • Heavy-duty machinery (mining crushers, conveyors, gearboxes)
  • Agricultural equipment (tractor wheel hubs, harvester transmissions)
  • Automotive (heavy-duty truck rear axles, differentials)
  • Energy equipment (wind turbine gearboxes, oil/gas pumps)
• Lubrication:
  • Grease lubrication:Lithium-based grease (filling volume 10%-15% of bearing cavity); synthetic grease for high-temperature scenarios
  • Oil lubrication:Suitable for high-speed/high-temperature operations (circulating oil systems recommended)
• Sealing options:
  • Standard:Open design
  • Optional:2RS (rubber seals), XAK (metal shields) (for dust/moisture protection)

Customization & Compatibility

• Adjustable parameters:
  • Bore tolerances (P5 precision available)
  • Contact angles (15°~29° for special orders)
  • Surface coatings (phosphating, black oxide) for enhanced corrosion resistance
• Compatibility:Compliant with general specifications, supporting direct replacement of standard models
• Certifications:ISO 355
