The oil injection hole of the existing equipment is easily blocked by metal debris generated during cutting, which prevents the lubricating oil from entering the bearing smoothly, aggravates bearing wear, shortens service life, and causes abnormal noise and vibration due to insufficient lubrication, affecting the cutting accuracy of pipe fittings. In addition, the oil injection mechanism cannot be independently disassembled and replaced, resulting in poor oil injection effect. Therefore, a rotating bearing with an external oil injection hole is needed to solve the above problems in pipe fitting cutting equipment. Utility Model Content
