32310 Tapered Roller Bearings Industrial Heavy Duty Roller Bearing

32310 Tapered Roller Bearing: Heavy Duty Performance For Industrial Applications

• 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°)

• 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)

• 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

• 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)

• 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
