Key Advantages

High Mechanical Efficiency: Helical gear design provides up to 96% transmission efficiency per gear stage.

Compact Integrated Drive: Eliminates separate motor beds, V-belts, and open gear sets, simplifying machine installation.

Low Noise & Smooth Running: Precision CNC gear grinding ensures quiet operation (under 68 dBA) and extended gear life.

Flexible Mounting: Modular housing designs allow easy conversion between foot, flange, horizontal, and vertical mounting.

Global Compatibility: Dimensions and shaft centers follow standard metric sizes for easy drop-in replacement.

Industrial Applications

Conveyor Systems: Belt conveyors, roller tracks, chain drives, sorting tables, and automated packaging lines.

Material Handling Equipment: Hoists, travel drives, transfer cars, positioning tables, and rotary feeders.

Processing & Mixing Machinery: Chemical agitators, food blenders, wastewater aerators, and liquid mixers.

Packaging & Textile Machinery: High-speed wrapping, cartoners, labeling lines, and spinning machines.

General Industrial OEM Machinery: Automated assembly lines, timber processing, and plastic machinery.

Mounting and Shaft Interface Configurations

To ensure seamless installation, mechanical mounting dimensions must match the host machine.

Foot-Mounted

Ideal for machines fixed to a rigid foundation. Verify mounting hole centers, center height, housing clearance, and shaft position.

Flange-Mounted

Designed for direct bolting to equipment wall panels. Verify flange outer diameter, bolt circle pitch, pilot fit tolerance, and shaft extension.

Solid Shaft

Used with external drive components (couplings, timing pulleys, sprockets). Verify radial load capacity, keyway dimensions, and shaft tolerances.

Hollow Shaft

Eliminates external couplings by sliding directly onto the driven shaft. Verify bore diameter, insertion depth, keyway layout, or shrink-disc dimensions.

Customization Options

Custom configurations are available for non-standard equipment requirements:

Mechanical Modification

Custom shaft dimensions, special keyways, stainless steel shafts, custom flanges, special paint finish (C3/C4 anti-corrosion).

Electrical Modification

Brake units (DC/AC brake), external forced cooling fans, dual-frequency windings, special terminal box positions.

Environmental Sealing

Viton oil seals for high ambient temperatures, IP66 waterproof enclosures, dust-proof protection.

Engineering Support

Custom Mechanical Design

Tailored output shaft diameters, keyways, special flanges, or heavy-duty housing materials for high-stress applications.

2D & 3D CAD Drawing Support

Instant CAD model files (STEP, DWG, IGES) supplied prior to ordering to streamline your machine design process.

Drop-in MRO Replacement

Reverse-engineering capability to match legacy gearboxes from major global brands without altering your existing machine base.

Quality Control Steps

Material Verification: Metallurgical analysis of alloy steel (20CrMnTi) for gears and shafts.

Gear Machining & Heat Treatment: CNC hobbing, carburizing, quenching, and core toughening for high fatigue strength.

Precision Tooth Grinding: CNC tooth profile grinding in a temperature-controlled environment for Class 6 gear accuracy.

Assembly & Inspection: Automated bearing alignment, dual-lip seal insertion, precision backlash measurement.

Full Factory Testing: Every unit undergoes noise tests, no-load running checks, vibration checks, and oil-tightness verification.

Export Packaging

Surface Rust Protection

All machined steel shafts and bright metal parts are treated with anti-rust oil and wrapped in protective film.

Sealed Moisture Barrier

Desiccant packs and heavy-duty PE vacuum wrapping prevent ocean shipment corrosion.

Reinforced Plywood Cases

Non-coniferous, fumigation-free wooden cases reinforced with steel strapping to sustain long-distance ocean and air transport.

Documentation & Markings

Clear shipping marks, lifting points, gross/net weight labels, and packing lists included with every crate.

Frequently Asked Questions

Q: Can you manufacture according to an existing gearbox drawing or sample?

A: Yes. Our engineering team can analyze your drawings or physical samples to match center heights, mounting dimensions, shaft tolerances, and ratio specifications.

Q: Are 3D CAD files available before placing an order?

A: Yes. We supply 3D models (STEP, IGES, SAT) and 2D CAD files to OEM design engineers for immediate drop-in verification during the design phase.

Q: Can you supply motors compliant with international standard voltages and energy efficiency levels?

A: Yes. Motors can be wound for regional voltages (380V 50Hz, 460V 60Hz, 220V 60Hz) and configured to IEC standard efficiency levels.

Q: What is your standard production lead time for sample and volume orders?

A: Standard configurations ship within 10–15 business days. Custom OEM orders or bulk shipments generally require 20–30 days depending on specification complexity.

Q: Can you supply direct replacement units for other major global gear motor brands?

A: Yes. Provide the competitor's model code, photos, or key interface dimensions, and we will configure a dimensionally interchangeable G Series drive.

Q: What information is required to receive an immediate quotation?

A: For new equipment: Motor power, required output speed (or ratio), mounting style, shaft style, and operating voltage. For replacement: Original nameplate photo and output shaft/mounting dimensions.
