– Product Model: 131401020704B003
– Product Name: Differential Housing Assembly
– Compatible Brands: Sany Heavy Industry Original Equipment
– Compatible Equipment: Sany wheeled excavators, light wheeled loaders, and other wheeled construction machinery
131401020704B003 is a Sany original equipment manufacturer (OEM) assembly, compatible with Sany wheeled excavators, light loaders, and other equipment, installed at the core of the differential transmission in the axle. Serving as the load-bearing base for the differential gears and bearings, it stabilizes gear operation, balances wheel speed, evenly distributes transmission load, stabilizes power output, and improves issues such as transmission jamming, vibration, abnormal noise, and uneven power distribution. It also prevents malfunctions such as housing cracking, oil leakage, positioning misalignment, and gear jamming, ensuring stable operation of the travel transmission system.
This product is forged from high-strength alloy cast steel in one piece, and undergoes tempering hardening, CNC precision boring, stress relief, precision grooving, and anti-corrosion and anti-rust treatment. Its dense and stable structure provides excellent resistance to impact, torsion, fatigue, and deformation. The original integrated sealing design ensures a tight fit, withstanding alternating high and low temperatures, heavy-load impacts, and high-frequency operation. It is not prone to deformation, loosening, seal failure, or dust and oil leakage, precisely ensuring gear meshing accuracy, reducing transmission losses, extending the service life of the differential assembly, and effectively reducing equipment maintenance costs.
