Seamless ring forging equipment
D51 vertical and D53K CNC radial-axial series for bearing rings, flanges, gear rings, wind power rings and cylindrical forgings, built for efficient hot ring production.
A ring rolling machine continuously expands and forms a heated ring blank through the main roll, mandrel roll and guide system. It helps reduce machining allowance, improve material utilization and support stable batch production.
D51 is suited to compact and medium ring production. D53K is designed for larger diameter, wider section and high precision radial-axial rolling.
D51 Vertical
Compact structure and easy operation for bearing outer rings, gear blanks, pipeline flanges, welding neck flanges and medium-size ring forgings.
D53K CNC Radial-Axial
Synchronized radial and axial control for large seamless rings, wind power flanges, hubs, thin-wall cylinders and alloy steel ring forgings.
Bearing inner and outer rings, gear blanks and slewing rings.
Pipeline flanges, welding neck flanges and petrochemical connection rings.
Wind power flanges, hub rings, nuclear power and energy equipment rings.
Ring forgings for vehicles, ships and heavy engineering machinery.
High temperature alloy and titanium alloy ring forging applications.
Copper alloy, aluminum alloy, stainless steel and other material rings.
Continuous rolling helps improve internal forging structure and ring dimensional consistency.
One-pass rolling is suitable for batch production of bearing rings, flanges and gear blanks.
Reduced material waste and machining allowance can lower the workload of later processing.
The following values are series ranges. The final configuration should be confirmed by ring drawing, material, heating method and target capacity.

| Production rhythm | Approx. 40-700 pcs/hour | Depends on ring size, material and automation level |
| Typical workpieces | Bearing rings, gear blanks, pipeline flanges | Wind power flanges, large gear rings, hubs, thin-wall cylinders |
Cut the billet by workpiece size and heat it to the required rolling temperature.
Prepare the ring blank with a press or forging hammer before rolling.
The main roll and mandrel roll expand the ring; D53K can also control axial height.
Check outside diameter, inside diameter, height and roundness after rolling.
Move to heat treatment, rough turning or precision machining according to the process plan.
For faster selection, please provide outside diameter, inside diameter, height, material, single-piece weight, target capacity and existing heating or forging equipment information.
