Motor grader rear axle PY210

Product overview：

The PY210 motor grader rear axle is specially designed for 200-220 horsepower motor graders and can be used as a high-end motor grader rear axle. The axle adopts the industry-leading three-stage design and supports customized production according to the specific requirements of equipment manufacturers, and can be flexibly adapted to various brands and models of motor graders. The balance beams on both sides and the intermediate axle body are securely connected by high-strength slewing bearings. This design not only ensures excellent load-bearing capacity and sealing, but also simplifies disassembly and maintenance, significantly reducing the difficulties associated with untimely maintenance and downtime. The wheel end adopts floating oil seal technology, which automatically compensates for wear gaps and maintains excellent sealing performance under harsh operating conditions such as extreme cold, high temperature, and dusty conditions. This effectively prevents lubricating oil leakage and completely isolates dust, sediment, and water vapor from penetrating the axle. This ensures long-term and stable operation of the grader's main rear axle components, as well as a reliable guarantee of the overall machine's operability.

Product Features:

• Excellent cross-country ability:

The driving axle of the grader adopts an innovative swing beam design, and the wheels can adaptively turn according to the ups and downs of the road, which greatly improves the cross-country ability and uniform grounding of tires. The adoption of high-quality swing bearings greatly reduces the friction resistance of the rocker when swinging, making the rocking smoother and more flexible, and the service life is much longer than the service life of traditional designs. The main gearbox can be equipped with world-famous brand automatic non-slip differential NO-SPIN, which can automatically lock slipping wheels on slippery, muddy roads covered with ice and snow, effectively preventing one-way skidding and idling, and further enhancing traction and operating safety in difficult conditions.

• Excellent braking performance：

The output terminal is equipped with an external disc brake. Compared with a traditional drum brake, braking torque is increased by 25%, heat dissipation efficiency is increased by 40%, and thermal decay is significantly improved. The external design allows friction plate wear to be detected at a glance, and daily inspection can be performed without disassembling the brake. Friction plate replacement is simple and quick, significantly reducing downtime during maintenance. The brake system is dustproof and waterproof, ensuring stable and reliable braking performance in muddy and swampy conditions.

• Stable and reliable quality:

Specialized production lines and high-precision equipment are used for processing and manufacturing, ensuring a high degree of consistency in each batch. All key components, such as bearings and seals, are manufactured by world-renowned brands such as SKF and NOK, ensuring a long service life. The spraying process is carried out on a dedicated production line with constant temperature and humidity, ensuring strict control of paint film thickness, and excellent adhesion and corrosion resistance. From raw material inspection at the factory, through precision machining, cleaning and assembly, spraying and drying, to finished product delivery, the entire process exceeds industry internal quality control standards, ensuring consistent quality, stability, and reliability for every motor grader drive axle.

Product Application：

As a leading professional manufacturer of drive axles for construction equipment with over 30 years of history, we always consider product quality to be the key to our success. Our 220hp motor grader rear axle, with its exceptionally low failure rate, has earned the long-term trust of many leading equipment manufacturers at home and abroad, including renowned companies such as Shantui, Liugong, UMG, and Amkodor. Our annual shipment volume continues to grow steadily, and it withstands rigorous testing in a variety of operating conditions, including extreme cold, high humidity, and dust.

Amkodor is an international group of companies headquartered in Minsk, Belarus, whose history dates back to 1927. Today, the group comprises 30 legal entities and 22 modern factories, producing over 6,500 types of products, including construction equipment, forestry equipment, agricultural machinery, municipal vehicles, as well as their spare parts and components. The company's business covers Belarus, Russia, Ukraine, Kazakhstan, and other CIS countries and is gradually expanding into the markets of Eastern Europe and the Baltic States. Guided by "reliability, innovation, and cooperation" as its core values, Amkodor strives to supply high-quality machinery and equipment to customers worldwide. Strict supplier selection and a constant commitment to product quality have made the company a benchmark enterprise in the field of construction equipment in the CIS region. Amkodor has finally chosen our grader drive axle, which is a high recognition of the quality of our products, technical strength, and service system.

The internationalization process of the PY210 motor grader rear axle began with an in-depth strategic cooperation with the renowned Belarusian manufacturer Amkodor. When Amkodor was developing a 210-horsepower grader for the Eastern European market, it urgently needed a highly reliable drive axle capable of adapting to the harsh climate and operating conditions of Eastern Europe. Upon learning of this requirement, our technical team did not rush to present a standard plan. Instead, they took the initiative to conduct an in-depth analysis of the characteristics of special working conditions, such as numerous marshy areas, long winters, and spring pulp harvesting in Belarus, and dispatched senior engineers to Minsk to conduct on-site research. Based on first-hand data, we systematically strengthened the key components: we optimized the elasticity and wear resistance of the floating seal at low temperatures, adjusted the micro-modification parameters of the gearbox to withstand frequent impacts during start-stop, and strengthened key body components. The rear axle of the motor grader was designed to withstand severe load fluctuations during permafrost thaw, and a slip-free differential lock ratio was selected that best suits local road conditions. After prototype testing and subsequent on-site verification, the motor grader's rear axle finally passed Amkodor's rigorous audit, demonstrating excellent performance characteristics. Serial delivery of auxiliary equipment was successfully implemented. Until now, there have been no quality complaints during the warranty period, and the product's reliability has been recognized at the highest level by reputable international markets. Amkodor's Technical Director once commented at the annual supplier conference: "This partner from China not only supplies high-quality products but also demonstrates a deep understanding of our operating conditions and a true spirit of partnership." This successful cooperation not only proves the effectiveness of our products but also opens the door to the high-end European market for us.
