The Hitachi Sumitomo SCX550 is a core equipment in the mining and construction sectors. The stability of its chassis directly determines the equipment's lifespan. VM's fully compatible chassis components are now available, including key components such as Tumbler Driving (2047688) and Seal Group 4245703.
Hitachi Sumitomo SCX550 Sprocket
1. Tumbler Driving - 2047688
Function: Serves as the core transmission unit for the track drive, transmitting power from the reducer to the track chain and bearing the impact loads of the equipment during travel.
Adaptability: Designed specifically for the SCX550, high-strength cast steel ensures resistance to deformation and wear under extreme operating conditions.
2. Seal Group - 4245703
Function: A multi-stage sealing system prevents mud, sand, and dust from intruding into the bearings and lubrication chambers, protecting the chassis' slewing mechanism from contamination.
Technical Highlight: The triple lip seal + dust ring design extends bearing life by over 30%.
3. Bearing Roller 4200411
Function: Supports the weight of the equipment and guides the crawler tracks for smooth operation, reducing friction between the track shoes and chassis frame.
4. Shaft Propeller - 2034540
Function: Connects the travel motor to the drive wheels, transmitting high torque and ensuring synchronized crawler track operation.
Safety Features: Carburizing and quenching enhance fatigue resistance and prevent fracture.
