Flange Mounted Worm Geared Motor
The G Series is a right-angle helical-worm geared motor designed for high-load, continuous-duty industrial applications requiring high reduction ratios, increased torque, and high-efficiency drive transmission.
Product Overview
The G Series is a right-angle helical-worm geared motor designed for high-load, continuous-duty industrial applications requiring high reduction ratios, increased torque, and high-efficiency drive transmission. Combining a high-efficiency helical gear stage with a smooth-running worm gear stage, the GS Series provides a compact 90-degree shaft configuration with direct drop-in replacement dimensions for standard European industrial gearboxes.

Technical Performance Advantages
High Efficiency & Low Noise: Combining a high-efficiency helical input stage with a quiet worm stage yields higher drive efficiency and lower operational noise compared to single-worm units.
Compact Right-Angle Layout: 90 degree shaft intersection positions the motor parallel to the driven machine, saving valuable floor footprint.
Wide Ratio Range: Ultra-broad reduction range (7.57 to 27093) covers high-torque, ultra-low output speed requirements without supplementary gearboxes.
Superior Thermal & Load Performance: Carburized alloy steel worms paired with wear-resistant tin-bronze wheels ensure stable thermal performance under heavy continuous loading.
Primary Applications
Conveyor Systems: Belt, slat, and chain conveyors where right-angle motor placement saves aisle space.
Material Handling & Warehousing: Automated storage systems, hoists, lifts, and transfer cars.
Process Machinery: Screw conveyors, industrial mixers, agitators, and dosing pumps.
Heavy Industry Equipment: Mining machinery, metallurgical feeders, chemical processing equipment, and packaging lines.
Configuration
Solid Shaft: Ideal for external drive components (couplings, pulleys, sprockets). Verify shaft diameter, extension length, keyway dimensions, and allowable radial load.
Hollow Shaft: Mounts directly onto driven machine shafts to save installation space. Check bore diameter, shaft length, keyway tolerances, and axial retention.
Shrink Disc: Provides a backlash-free clamping mechanism between the hollow gearbox shaft and the machine shaft for reversing or high-vibration applications.
B5 / B14 Flanges: Must match the pilot diameter, bolt circle diameter (PCD), and bolt hole arrangement of the driven machine drawing.
Installation, Mounting & Maintenance
Pre-Installation Verification: Inspect output shaft dimensions, keyways, pilot surface diameters, and motor ventilation clearances before mounting.
Alignment Precision: Align gear unit shafts accurately with driven equipment using precision alignment shims. Never use mounting bolts to force gearbox positioning.
Direct Shaft Mounting: For hollow-shaft models, coat the driven shaft with anti-seize paste prior to assembly. Ensure radial loads remain within permissible limits.
Thermal & Mounting Considerations: For vertical mountings (M2 or M4), verify thermal capacity and ensure proper lubrication access to upper bearings.

Frequently Asked Questions
Q: Can the G Series directly replace an existing SEW S-Series helical-worm geared motor?
A: Yes. The G Series shares identical key mounting dimensions, center heights, flange dimensions, and shaft diameters with standard European helical-worm gearboxes, making it a direct drop-in replacement.
Q: Are 3D CAD models available before placing an order?
A: Yes. We can provide .STEP or .IGS 3D files for your exact configuration (power, ratio, flange, and shaft style) so you can verify mechanical clearance in your digital machine design.
Q: What is the difference between GSF and GSAF models?
A: GSF features a B5 mounting flange with a solid output shaft. GSAF features a B5 mounting flange with a hollow keyway shaft for direct shaft mounting.
Q: How do I select between a B5 flange and a B14 flange?
A: B5 flanges feature a larger outer diameter with clearance through-holes for bolts. B14 face flanges feature a smaller overall footprint with threaded blind holes, ideal for tight space constraints.
Q: Can these geared motors be operated with a Variable Frequency Drive?
A: Yes. When paired with an inverter-duty motor, the speed can be safely adjusted via VFD across a wide frequency range.
