What Extrusion Lines Demand from a Gearbox

An extruder gearbox is not a standard reducer. It must deliver high torque at low screw speed, absorb axial thrust from the screw, and run continuous S1 duty near a hot barrel. Anand Gears extruder gearboxes cover roughly 5.5–75 kW across series with ratios about 3.5:1 to 50:1, with reinforced thrust bearing design and elevated-temperature options.

Continuous S1 duty for long production runs

Reinforced axial thrust capacity at the screw end

Ratios sized for typical 50–150 RPM screw speeds

Series options for standard, high-temperature, and dual-motor layouts

Oil circulation / cooling options for thermal load

IEC motor flanges and custom coupling interfaces

Line Types

Where These Drives Are Applied

Blown & cast film

Steady screw speed and torque for film bubble or cast sheet quality; thermal stability reduces rate drift.

Sheet & profile

Higher continuous torque at controlled RPM for rigid profiles and thick sheet.

Rubber extrusion

Elevated temperature tolerance and robust seals for hose, seal, and profile rubber lines.

Compounding / dual drive

Higher power dual-motor series where the process demands more torque than a single motor package.
