  • Hexagon TC insert layouts are configured so that there is no direct pathway for the fluid to wash or erode. This helps with keeping fluid flow through the bearing pack to a minimum as radial bearings act as a flow restrictor as well.
  • All TC radial bearings are well suited for high RPM, pressures, temperatures, corrosive and erosive environments.
  • Hexagon TC inserts are capable of covering 70% + of bearing surface areas.
  • Typical life expectancy: 300 – 400 hours. (Run life solely depends upon drilling environment, mud composition, bend settings, carbide saturation and quality)
  • Average hardness of hexagon TC inserts: > 70 HRC.
  • Average substrate body hardness: 28-36 HRC. (Many material and heat treating options are available)


  • Common sizes available include but are not limited to: 2 1/8", 2 3/8", 2 7/8", 3 3⁄4", 4.75", 5", 6.25", 6.50", 6.75", 7.75", 8", 9 5/8", and 11 1⁄4"
