Product Description
TD40 Sprocket Undercarriage Parts
for Construction Machinery
1. What Is sprocket ?
Teeth serve a critical function in the machine's transmission
system, meshing with gears or pulleys to facilitate the transfer of
rotational energy. Their unique structure and meticulous processing
guarantee high precision, reliability, consistent operation, and
efficient energy transmission.

2. Advantages / Features
(1) Low-alloy cast steel:
Low-alloy cast steel has exhibited remarkable mechanical properties
and enduring durability across various fields, thanks to its
exceptional blend of high strength, superior toughness, and
excellent corrosion resistance.
(2) High-hardness rail surface (HRC > 50):
The product surface is endowed with exceptional wear resistance due
to the design of its high-hardness track surface, which boasts a
hardness value exceeding HRC 50. This significant wear resistance
effectively minimizes friction-induced wear, thus prolonging the
product's service life.
(3) Tempering to prevent cracking and fragmentation:
Tempering, a crucial heat treatment process, effectively mitigates
residual stress and brittleness in materials through precise
regulation of the heating and cooling cycles. This process not only
enhances the material's toughness and crack resistance but also
ensures greater stability and reliability of the product under high
stress and shock conditions.
(4) Accurate design and production perfect coordination:
One of the pivotal factors in ensuring superior product quality and
performance is meticulous design and production coordination.
During the manufacturing process, each component undergoes rigorous
calculation and precise fabrication to guarantee the exactness of its dimensions, shape, and positioning.
