1.5kW Motor Standard

Energy-efficient 1.5kW motor delivers consistent torque across all models

Key Features

Both the upper and lower rollers are manufactured from bearing steel, a material chosen specifically for its hardness and resistance to surface deformation. This means the rollers maintain their profile and dimensional accuracy even after thousands of bending cycles, reducing maintenance frequency and ensuring consistent duct quality over time.

The SBW11G series is available in 2×1020, 1.5×1270, and 1.2×1530 configurations, allowing buyers to select the right balance of material thickness capacity and working width for their production needs. All three models share the same roller diameter and motor specification, simplifying spare parts inventory and operator training across a multi-machine shop.

A foot pedal controls roller engagement, allowing the operator to use both hands to feed, position, and guide the workpiece. This improves forming precision on curved sections and elbows while reducing operator fatigue during repetitive production runs.

Weighing between 220kg and 280kg with a narrow 550mm depth, these machines occupy minimal floor space. The enclosed base with integrated storage cabinets keeps tooling and accessories organized, and the rigid steel frame absorbs vibration during operation without requiring additional floor anchoring.

A 1.5kW motor drives the rollers through a geared reduction unit, providing steady torque at low energy consumption. This makes the machine suitable for facilities with limited power infrastructure while still delivering the force needed to form mild steel up to 2mm thick at 245MPa yield strength.

Technical Specifications

The electric motorized roll bending machine is used for round duct, or an elbow to bend a workpiece. Available in a variety of models and curved shapes.
