Our Core Strengths

Standardized Production Process Flow

Raw Material Forging & Normalizing
Premium alloy steel (20CrMnTi / 40Cr) forgings undergo strict normalizing and ultrasonic flaw detection to eliminate internal stress, optimize grain structure, and ensure superior core impact resistance.

01
02
Precision CNC Machining & Gear Hobbing
Multi-axis CNC lathes complete high-precision turning of reference datums and end faces. High-speed CNC gear hobbing and shaping machines precisely form the initial tooth profile with strict geometric allowances.
Controlled Carburizing & Heat Treatment
Processed in multi-purpose atmosphere-controlled furnace lines. Surface carburizing and quenching achieve a wear-resistant surface hardness of HRC 58–62, while preserving tough, shock-absorbing cores.

03
04
High-Precision CNC Gear Grinding
Advanced CNC profile gear grinding machines eliminate heat-treatment micro-distortions. Tooth flanks are precisely modified with crowning to achieve DIN Class 5–6 accuracy, ensuring whisper-quiet running.
Housing Machining & Clean Modular Assembly
Gearbox housings are machined on CNC horizontal machining centers for micron-level bore concentricity. Assembled in a clean workshop with top-tier bearings (SKF/NSK/C&U) and dual-lip oil seals to guarantee zero oil leakage.

05
06
100% Comprehensive Testing & Export Packaging
Every unit undergoes 100% full inspection: gear measurement center (CMM), dynamic running test (vibration, noise, temperature rise) and sealing test before multi-layer anti-rust film and solid plywood case packaging.

Core Advantage

Ultra-Silent Transmission

High-precision gear grinding delivers tooth surface roughness as low as Ra 0.4, with tight meshing, low vibration and noise for smoother equipment operation.

Extended Service Life

Premium materials matched with precise heat treatment ensure wear-resistant tooth surfaces and impact-resistant core, cutting maintenance and replacement costs.

All-Condition Adaptation

Custom solutions for high-speed heavy load, corrosion resistance and food-grade scenarios, eliminating trial-and-error costs in product selection.

Cost-Effective & Reliable Delivery

Scaled production supports tiered pricing for bulk orders with consistent quality; full-process control guarantees stable lead time and complete after-sales support.

Frequently Asked Questions (FAQ)

Can your gearboxes directly replace international brands like SEW, Flender, or Bonfiglioli?

Yes. Our modular gearboxes (R, F, K, S series and planetary units) are designed to standard international mounting dimensions. They can achieve 1:1 direct interchangeability in mounting hole positions, shaft diameters, input flanges, and gear ratios without modifying your existing machinery.

What technical parameters do I need to provide to select the right gearbox?

To help our engineering team calculate the ideal model, please provide: input motor power (kW/HP), input/output speed (RPM) or gear ratio, required output torque (Nm), mounting position (horizontal/vertical), and the specific application or working environment.

What is the typical lead time for standard and customized gearboxes?

For standard modular models (R/F/K/S series and cycloidal gearboxes), lead time is typically 7–15 days. For customized units with special ratios, shafts, or special flanges, lead time is usually 20–30 days. Emergency spare parts are dispatched within 48 hours.

How do you guarantee zero oil leakage and transmission durability?

All gearboxes utilize precision-machined CNC housings for micro-level bore concentricity, premium dual-lip skeleton oil seals, and top-tier bearings (SKF/NSK/C&U). Every unit undergoes a 100% dynamic running test (vibration, noise, temperature rise) and sealing test before export packing.

What is your MOQ, warranty policy, and do you supply test reports?

Our MOQ is 1 unit (sample order supported). All products come with a 12-month comprehensive warranty. Each shipment can be provided with full documentation, including dynamic test records, material certificates, CMM gear inspection reports, and CE/ISO compliance certificates.
