The 32010 tapered roller bearing features a single-row separable design, with key dimensions as follows:

• Bore diameter (d):50mm
• Outer diameter (D):80mm
• Width (T):20mm
• Weight:Approx. 0.32kg
• Contact angle:10°~14°, enabling it to handle both radial loads and one-way axial loads.

1. High Load Capacity
   • Dynamic load rating (Cr):54.5kN (EZO) to 62kN (TIMKEN)
   • Static load rating (C0r):85kN (EZO) to 99.5kN (TIMKEN), suitable for heavy-duty industrial machinery.
   • Constructed from GCr15 high-carbon chromium bearing steel (or equivalent materials like SUJ2), heat-treated to achieve a surface hardness of HRC58-62, ensuring excellent wear and fatigue resistance.
2. Precision & Durability
   • Standard precision class (P0), with a limiting speed of 4500~6300rpm (grease-lubricated) and 6700~9000rpm (oil-lubricated), meeting medium-to-high speed operation requirements.
   • Separable structure (inner ring + roller assembly and outer ring are independent), simplifying installation, adjustment, and maintenance.
3. Environmental Adaptability
   • Compatible with shaft diameter tolerances H7/k6 and housing bore tolerances J7, aligning with ISO 355 standards.
   • Available in stainless steel versions (e.g., 32010-B-XL) for corrosive environments, and high-temperature models (e.g., 32010/S1) rated for continuous operation up to 300°C.

1. Industrial Machinery
   • Gearboxes, conveyors, and crushers in mining and metallurgy, where it withstands high radial loads and axial thrust from material processing.
   • Machine tool spindles and presses, ensuring precision under cyclic heavy loads.
2. Automotive & Transportation
   • Truck rear axle supports and agricultural machinery wheel hubs, handling dynamic loads from uneven terrain.
   • Heavy-duty vehicle transmissions, providing stability during high-torque operations.
3. Energy & Power
   • Wind turbine gearboxes, supporting axial loads and yaw moments to maintain power generation efficiency.
   • Industrial pumps and compressors in oil and gas applications, resisting corrosion and high-pressure environments.

• Lubrication:
  • Grease lubrication: Use lithium-based grease (e.g., SKF LGMT2) with a filling volume of 10%-15% of the bearing space. For high-temperature scenarios, synthetic grease (e.g., Klüber 高温脂) is recommended.
  • Oil lubrication: Circulating oil systems are ideal for high-speed or high-temperature conditions, ensuring effective heat dissipation.
• Sealing:
  • Standard open design; optional labyrinth seals or metal shields (model suffixes "-2RS" or "-XAK") protect against dust and moisture intrusion.

• Compliant with ISO 355 international standards and IATF 16949 (for automotive applications), ensuring consistency in mass production.
• Cross-brand compatibility with major manufacturers (SKF, FAG, NSK), supporting direct replacement (e.g., 32010-B, HR32010XJ).
