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.
