CG50.6-8 Internal Gear Ring | Construction & Heavy Truck Spare Parts Wheel Loader Parts SDLG XCMG

The CG50.6-8 internal gear ring is a heavy-duty transmission component designed for construction machinery and heavy-duty truck drivetrain systems. Manufactured with precision gear machining and heat treatment, this internal gear delivers stable torque transmission, outstanding wear resistance and long service life under high-load, shock and harsh working conditions.

It is widely used in wheel loaders, excavators, heavy trucks and other engineering vehicles. Strict dimensional control ensures perfect matching with original assemblies, effectively reducing gear tooth breakage, abnormal noise and premature failure of the reduction assembly. Our internal gear ring undergoes full inspection on gear profile, tooth surface hardness and dimensional tolerance before shipment to guarantee consistent quality for bulk orders.

• High-strength alloy steel material, carburizing and quenching treatment for excellent wear and impact resistance
• Precision CNC gear cutting, low tooth backlash, smooth power transfer, less running noise
• Strict dimensional tolerance control, direct replacement for matched assemblies
• Suitable for heavy load, dusty and high-temperature working environments
• Stable performance, reduces maintenance downtime for construction and transport fleets
