Plastics & Rubber Extruder Drive Applications
Continuous-duty extruder reducers for film, sheet, profile, and rubber lines — high axial thrust capacity and thermal control for long production runs.

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.
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.

FAQ
Plastics & Rubber Extruder Drive Applications — Common Questions
How is an extruder gearbox different from a standard helical unit?
Extruder units are engineered for continuous high axial thrust, long S1 duty near elevated ambient temperatures, and screw-speed ratios — not only for torque and mounting feet.
What power range do you cover?
Across series, approximately 5.5 kW to 75 kW depending on standard, high-temperature, or dual-motor configuration.
Can you help select ratio from screw RPM?
Yes. Ratio ≈ motor RPM / screw RPM. Share both speeds and we confirm thermal and thrust capacity for that duty.

Tell us the duty and we’ll send you a number
Power, input speed, and either the ratio or the output speed you need are usually enough to start. Our engineers reply on the same working day.
Have a nameplate photo, a drawing, or the old unit in front of you? Send it on WhatsApp — that is the fastest route to a number.
