Royal "Oil Country" Big-Bore Bull Head Live Center

Live Center and Modular Head Sold Separately.

Expertly crafted in the USA, specifically for machining large diameter pipes in the oil and gas industry, yet versatile enough for any large-bore applications. Unlike standard bull head live centers, the modular head design of Royal "Oil Country" Big-Bore centers positions the workpiece nearer to the bearing assembly for increased strength and lasting performance. With interchangeable heads relieved to achieve optimal strength-to-mass ratio, fewer models are needed to cover a wider range of bore sizes. The bearing setup includes a heavy-duty tapered roller bearing, a large axial thrust bearing, and two precision needle bearings for unparalleled precision and durability in the most challenging production settings.
