CR 38647 Tapered Roller Bearing (40x80x20mm) | High Axial & Radial Load Capacity | Precision Ground

The CR Model 38647 is a high-performance Tapered Roller Bearing engineered for rigorous industrial applications where combined radial and heavy axial loads are present. Its inherent design, featuring four components—the inner ring (cone), outer ring (cup), tapered rollers, and cage—allows it to efficiently manage high stress concentrations, providing excellent rigidity and precise shaft guidance. Constructed from hardened SAE 52100 high-carbon chromium steel, the 38647 ensures exceptional wear resistance and extended fatigue life under continuous operation. The optimized roller profile geometry reduces edge stress, significantly enhancing durability and reliability in critical machinery. Designed for ease of installation and maintenance, the separable cone and cup allow for independent mounting, simplifying clearance adjustments during assembly. This bearing is a standard solution for demanding industrial transmissions, heavy-duty vehicle axles, machine tool spindles, and agricultural machinery, offering superior operational efficiency compared to standard ball bearings in equivalent dimensions. Choosing the 38647 guarantees reduced downtime and a lower total cost of ownership (TCO) by providing maximum service intervals and consistent performance in contaminated or high-temperature environments. Our strict manufacturing tolerances meet or exceed P5 precision standards, ensuring interchangeability and predictable performance across all demanding applications.

Key Features

  • Optimized roller profile geometry for enhanced load distribution and reduced edge stresses.
  • High-grade SAE 52100 steel construction for maximum wear resistance and operational longevity.
  • Separable design (Cone and Cup) facilitating easier mounting and precise axial clearance adjustment.
  • Exceptional capacity to manage simultaneous high radial and axial loads.
  • Precision manufactured to tight tolerances ensuring predictable performance and industry interchangeability.
  • Ideal for use in high-stress applications including heavy vehicle wheel ends and industrial gearboxes.
