For bearing ring production, the machine forms heated ring blanks into outer rings or other circular bearing components. The rolling process improves material distribution and helps reduce machining allowance.
For gear blank production, ring rolling creates circular forged blanks that can later be machined into finished gears. This supports better use of material compared with cutting from larger solid stock.
The machine uses a rolling wheel, mandrel and support rollers to expand the ring diameter while reducing the wall thickness. Hydraulic force and controlled movement help maintain stable forming during hot rolling.
Important selection factors include ring outside diameter, ring width, material, section size, production volume and required accuracy. Bearing steel, alloy steel, carbon steel and stainless steel may all be suitable depending on the application.
For manufacturers producing bearing rings, gear blanks, sleeves or machinery rings, a ring rolling machine can be a strong addition to the forging production process.
