Ring rolling is made on special ring rolling machine (also called ring expanding machine),which reduces the thickness and enlarges the inner diameter and outer diameter of the work piece to get required cross section. Novel appearance,beauty,light weight, good rigidity, high precision, tight structure, safe using and convenient operation as well easy maintenance are the characteristic for the ring rolling machine. Ring rolling machine is widely used for bearing forging industry. All kinds of inner rings and outer rings of bearing rings can be rolled on it. Bearing rings track and baffle also can be rolled. Our ring rolling machine is widely used in China, also exported to Belgium, Russia, Romania, Turkey, South Korea, India, Pakistan etc more than 10 countries in the world.

Our Advantages
A. Appearance of machine is novel, machine base is weld-forming by steel plate, so structure is light with good rigidity. B. Reasonable and scientific design for machine tool, especially new design and development of distribution of main shaft bearing, it has high rolling accuracy. C. Upper sliding block is rectangle section with good rigidity. The length of guide rail of sliding block is increased to 5-6 times of sliding block journey, guide accuracy is high. D. Main parts of machine are all made of cast steel or high-quality alloy steel. E. Sealed lower supporting bearing makes the normal working in bad condition. F. YX seal and 0 type ring are adopted in accordance with lnternational standard, cylinder is low resistanceperformance is reliable and good abrasive resistance G. The rolling wheel is fixed with an internal cone-shaped expansion ring and its locating accuracy is high, therolling wheel can be disassembled and replaced easily. H. The precision rolling structure is driven in a synchronized mode and run smoothly, a wide adjusting rangeis available. I. A muffler is equipped for exhausting system of gas pipeline to reduce noise and protect environment.
