The WG2210040109 Main Shaft Sliding Sleeve is a key shifting engagement component in heavy-duty truck transmissions, also known as the main shaft gear engagement sleeve.
Its main function is to connect the main shaft with different gear positions, enabling smooth gear engagement and power switching within the transmission system. It is a critical part to ensure stable power delivery and smooth shifting performance.
This component is widely used in heavy-duty truck gearbox assembly, maintenance, and replacement applications.
Key Function
- Connects main shaft and gear system accurately
- Enables smooth engagement of all transmission gears
- Ensures stable and efficient power switching
- Supports reliable shifting performance under load
Product Advantages
● Smooth Shifting & Precise Operation
The internal spline is precision-machined with high accuracy and smooth surface finishing, ensuring:
- Smooth sliding without sticking
- Tight and stable gear engagement
- Elimination of gear grinding, noise, and slipping
This improves shifting feel, reduces driver fatigue, and enhances driving comfort.
● High Strength & Impact Resistance
Manufactured from high-strength alloy structural steel through precision forging, the sleeve offers:
- Excellent toughness and hardness balance
- Strong resistance to torque impact during shifting
- High durability under frequent gear changes
It is not easy to deform, chip, or wear out, even under heavy-duty operation.
● Dual Heat Treatment for Long Service Life
The gear teeth surface adopts quenching + precision grinding technology, providing:
- Uniform hardness distribution
- Strong wear resistance
- Excellent fatigue resistance
This significantly extends service life under continuous heavy-load conditi
● Built for Heavy-Duty Working Conditions
Specially designed for frequent shifting and high-load applications, suitable for:
- Long-distance logistics transport
- Mountain and uphill driving conditions
- Heavy cargo and construction vehicles
Maintains stable performance without loosening or failure over time.
