[0002] Roller guides are devices installed on the rolling mill frame, located before and after the rolls, to guide and support the workpiece as it enters and exits the rolling mill. The function of the guide device is to correctly guide the workpiece into the roll pass and ensure that the workpiece deforms stably in the pass.

[0003] During the movement of traditional roller guides, the guide bearings are lubricated with oil and gas. The lubricating oil pipeline extends from the oil and gas holes in the guide box base to the oil and gas receiving pipe of the support arm, and is then transported to the guide bearings by the oil and gas receiving pipe of the support arm shaft. However, during long-term use of traditional roller guides, gaps are prone to occur at the connection between the receiving pipe and the oil and gas pipeline, which can cause oil and gas to leak to the outside of the device, thereby affecting the stable use of the device.
