W11 Series 3-Rollers Symmetrical Mechanical Rolling Machine

The W11 series symmetrical 3-roller mechanical plate rolling machine is an upgraded version of the traditional three-roll double-pinch plate bending machine. Designed to meet the needs of modern fabrication shops for strength, ease of use, and versatility, this machine benefits from decades of experience in manufacturing heavy-duty plate rolling equipment.

Key Features
Proven Symmetrical 3-Roller Design: The symmetrical arrangement of the three rollers ensures balanced force distribution, making the machine robust, durable, and easy to operate. It is ideal for rolling cylindrical shells and forming basic curved parts.

High Bending Precision: The optimized RGS design minimizes the distance between the bending points, ensuring higher forming accuracy and consistent roundness in finished workpieces.

Reliable MCS Bearing System: Each bending roller is supported by four independent bearings as standard. This MCS bearing system provides higher reliability and greater load absorption capacity, extending the machine’s service life.

Enhanced Versatility for Conical Forming: The bearing system also allows for a wider range of side roller tilting angles, significantly improving versatility when rolling conical workpieces.

Cost-Effective & Low Maintenance: As a mechanical type rolling machine, the W11 series offers an economical solution with fewer complex hydraulic components, resulting in lower maintenance requirements and reliable performance.

Applications
This symmetrical 3-roller mechanical rolling machine is widely used in industries including:

  • Pressure vessel and boiler manufacturing
  • Steel structure and tank fabrication
  • Piping and ductwork production
  • General metalworking workshops
