The WG2229020030 Thrust Bearing Locking Plate is a critical fastening and positioning component used in heavy-duty truck transmissions.
Its primary function is to axially locate and securely lock the thrust bearing in place, preventing loosening or displacement during operation. As an essential part of the gearbox transmission system, it directly affects the stability, safety, and reliability of heavy-duty truck performance.
This product is manufactured strictly according to OEM standards, ensuring perfect fitment for corresponding transmission models.

Key Function
- Provides axial positioning for thrust bearings
- Prevents loosening and axial movement during operation
- Ensures stable and smooth transmission performance
- Enhances gearbox structural reliability and safety
Product Advantages
● High Strength & Fatigue Resistance Material
Made of high carbon manganese steel / 65Mn spring steel, the locking plate features:
- High strength and excellent toughness
- Strong fatigue and vibration resistance
- Stable performance under continuous heavy load
After professional quenching and tempering heat treatment, it resists deformation and cracking even under long-term operation.
● Precision Manufacturing for Perfect Fit
The product is produced using precision stamping technology, ensuring:
- Strict OEM-compliant dimensions
- Minimal tolerance deviation
- Smooth edges with no burrs
This guarantees accurate assembly and reliable locking performance.
● Anti-Corrosion Surface Treatment
The surface is treated with blackening or phosphating, providing:
- Excellent resistance to oil and corrosion
- Strong durability in lubricated environments
- Extended service life in harsh gearbox conditions
● Stable Locking Structure Design
Designed with a ring-shaped structure and dual symmetrical locking tabs, it provides:
- Quick and easy installation
- Secure and stable locking effect
- Strong resistance to loosening under vibration
This ensures the thrust bearing remains firmly fixed in position.
