GW42 Auto Steel Bar Bender Rebar Bending Machine

The GW42 is an automatic rebar bending machine designed for bending round and deformed (class) steel bars. It features an automatic/digital control panel, worm-gear drive and is built for construction and precast applications that require fast, repeatable bends.

The series includes GW40E, GW40F, GW42D, GW42, GW50C and GW50E. Each model differs in bending range, disk diameter, overall size and weight to suit different site needs.

GW42 bends round bars from 6 mm up to 42 mm and class (deformed) bars from 6 mm up to 32 mm.

Motor power options are 3 kW or 4 kW (model-dependent). Motor speed is 1,440 rpm.

The machine accepts three-phase supply—standard options are 220 V, 380 V or 415 V. Custom voltage configurations are available on request.

The GW42 model uses a 350 mm bending disk. (GW50-series models use a 400 mm disk.)

The GW42 overall size is 850 × 900 × 900 mm and its net weight is approximately 310 kg.

The GW42 uses a worm-gear driving mechanism and operates via an automatic digital control panel for preset and repeatable bends.

Yes — the digital control panel allows you to preset bending angles and counts for repeatable production. Actual accuracy depends on material, bar size and setup; fine adjustments are made through the control panel.

It is designed for typical construction rebar: round bars and deformed (class) bars within the specified model ranges (for GW42: round 6–42 mm, class 6–32 mm).

Install on a level, stable surface with sufficient clearance. Connect to the specified three-phase supply by a qualified electrician, ensure correct phase wiring and proper earthing. Consult the supplier for foundation or anchoring recommendations.

Regular maintenance includes daily cleaning of debris, periodic lubrication of gears/worm gear and pivot points, routine inspection and tightening of fasteners, and inspection of the motor and electrical connections. Follow the supplier's maintenance schedule for intervals and lubricants.

Operators should wear PPE (gloves, eye protection, safety boots), keep hands and loose clothing away from moving parts, ensure emergency stop and guards are functional, and only allow trained personnel to operate the machine. Follow local machine-safety regulations.

Common spare parts (bending disks, rollers, electrical components, gears) and accessories are typically available. Contact the supplier with your model number for part numbers, lead times and pricing.

Voltage and certain configuration customizations are available. Warranty terms, CE/ISO or other certifications and shipping options vary by supplier—contact the manufacturer or dealer for detailed warranty coverage, certifications and customization options.
