Friction Head of Roller

We design the solid belly workpiece instead of regular hollow structure, which greatly reduces the weight of the workpiece, and reduces the rotational inertia and rotational centrifugal force. and change double bearing single-end support to bearing double-end support in the friction head, so that the friction head installation support is reliable, stable rotation, energy saving and environmental protection, easy to replace, hard to damage.
