Hexagonal TC Bearings
- The configuration of Hexagon TC blade layout prevents direct paths for fluid erosion or abrasion. This helps to keep the fluid flow through the bearing assembly to a minimum, as radial bearings also act as flow restrictors.
- All TC radial bearings are well-suited for high-speed, pressure, temperature, corrosive, and erosive environments.
- Hexagon TC blades can cover 70%+ of the bearing surface area.
- Typical expected lifespan: 300-400 hours. (Operational life is entirely dependent on drilling environment, mud composition, bend settings, carbide saturation, and quality)
- Average hardness of Hexagon TC blades: >70 HRC.
- Average hardness of base material: 28-36 HRC. (Various material and heat treatment options available)
- Common sizes 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".
