Product Description
R140LC Bulldozer Sprocket Undercarriage Parts
for Construction Machinery
1. What Is sprocket ?
These impact forces may come from irregularities in the ground, sudden load changes during excavation operations, and so on.
The effect of vibration on the whole structure of the excavator can be significantly reduced and the service life of the equipment can be extended through the shock absorption effect of the driving wheel.

2. Advantages / Features
(1) Low-alloy cast steel:
This material can not only easily cope with high loads and complex stress conditions, but also maintain stable performance in extreme and harsh working environments. By subtly adding a small amount of alloying elements, the internal structure of the material can be further optimized, thus significantly improving its mechanical properties and processability.
(2) High-hardness rail surface (HRC > 50):
Reduced wear also means reduced downtime and maintenance costs due to wear, resulting in higher economic benefits for users.
(3) Tempering to prevent cracking and fragmentation:
For products that need to work under harsh conditions, tempering is a strong safeguard against cracking and fragmentation.
(4) Accurate design and production perfect coordination:
This precision not only improves the overall performance and reliability of the product, but also makes the individual components fit more closely and smoothly.
