Royal “Oil Country” Big-Bore Bull Head Live Centers

  • Designed specifically for machining large diameter pipes for the oil and gas industry, but suitable for all large-bore applications.
  • In contrast to standard bull head live centers, the modular head design of Royal “Oil Country” Big-Bore centers positions the workpiece closer to the bearing assembly for greater rigidity and longer operating life.
  • Interchangeable heads are relieved to achieve the optimal strength/mass ratio, and are sized to cover a wider range of bore sizes with fewer models.
  • Bearing configuration consisting of a heavy-duty tapered roller bearing, a large axial thrust bearing, and two precision needle bearings provides exceptional accuracy and rigidity under the most demanding production conditions.
