Timken HH 224 346 XA 72 Heavy Duty Tapered Roller Bearing | High Load Capacity TRB

The HH 224 346 XA 72 is a premium, high-capacity Tapered Roller Bearing (TRB) engineered for the most demanding heavy industrial applications, including large gear drives, rolling mills, and mining machinery. Its precision-optimized internal geometry allows it to manage extreme radial and axial loads simultaneously, ensuring superior rigidity and reduced shaft deflection under peak operational stress. Manufactured using high-cleanliness, case-carburized steel, this bearing provides an exceptional fatigue life that far exceeds standard industry requirements, minimizing unexpected downtime and maximizing machine uptime in critical operational loops. Designed for ease of installation and maintenance, this specific configuration (XA 72) offers enhanced surface finishes on the raceways and optimized roller profiles to achieve lower friction coefficients and cooler running temperatures. Selecting the HH 224 346 XA 72 ensures not only compliance with stringent ISO standards but also a significant improvement in Total Cost of Ownership (TCO) through extended service intervals and unparalleled reliability. This bearing is the choice for engineers prioritizing performance and longevity in severe-service environments where bearing failure is not an option.

Key Features

  • Optimized Roller Profile: Reduces edge stress and extends L10 bearing life significantly.
  • XA Precision Grade: Enhanced internal tolerances for superior running accuracy and reduced vibration.
  • High Static Load Capacity: Engineered to withstand extreme shock loads and momentary overload conditions (Co=1,150 kN).
  • Case-Carburized Steel: Provides a tough, wear-resistant surface combined with a ductile core to prevent fracture.
  • Integrated Seating Angle: Facilitates precise axial setting and optimized load distribution.
