Recently, the technical and procurement team from a leading Russian tractor OEM visited our production facility for a full factory audit and technical discussions centered on a spur gear supply program for tractor transmission assemblies. Both sides aligned on the product technical specification and reached a consensus on volume supply cooperation.

The customer’s team toured our forging blank workshop, precision gear hobbing facility, continuous controlled-atmosphere heat treatment line, and ZEISS-compliant quality control and gear performance laboratory. They focused on verifying key production steps including precision hobbing forming, carburizing & quenching strengthening, and tooth root shot peening, and reviewed our full-process control protocols covering alloy steel batch traceability, in-process parameter management, and finished gear fatigue & impact testing.

During discussions, the customer noted that tractor transmissions operate under heavy-load, high-impact conditions and must withstand Russia’s extreme cold climate, placing strict requirements on the spur gears’ low-temperature toughness, bending strength and wear service life. Drawing on years of experience in agricultural transmission applications, our engineering team optimized the alloy structural steel grade and heat treatment process parameters, reduced stress concentration by adjusting the tooth root fillet radius, and outlined clear capacity guarantees and lead times for volume production. The customer expressed full recognition of our ability to tailor solutions to specific operating conditions and deliver stable mass production.

Following the on-site visit, the customer formally confirmed the first trial batch order of 3,000 External spur gears, and reached a formal preliminary agreement on the 2027 full-range gear supply framework for tractor transmissions. Both sides agreed to proceed with low-temperature bench testing of samples and small-batch field validation in tractors, as a step toward deeper, full-line transmission supply cooperation.

As an original manufacturer with deep roots in industrial power transmission, we build our products around heavy-load reliability and application-specific adaptability to meet diverse operating requirements across the globe. Moving forward, we will continue to refine our agricultural transmission technology and deliver high-quality gear and gear reducer supply solutions to customers across Eurasia.
