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.
