Technology and Performance
Machine Balance and Performance Optimization
The collaborative design of the undercarriage idler and chassis system of the D11 bulldozer means that we not only focus on the performance of a single component, but the coordinated operation of the entire machine. This design ensures the balance of the machine when doing bulldozing operations, whether on flat land or uneven terrain, can remain stable, reduce body shaking, and provide more precise control.
Optimized machine balance also means better weight distribution, which helps reduce pressure on the ground and protect the working surface from damage, while also reducing wear on machine parts and extending the service life of the equipment.
Duo-Cone™ sealing technology
You may be worried about the maintenance of the equipment in a harsh jobsite environment. Our idler uses Duo-Cone™ sealing technology to provide you with a solution. This seal design is symmetrical, which means it provides equal protection on both sides of the guide wheel.
Keep the lubricant leak-proof for a long time, which means reduced maintenance costs and time for customers. You don't need to check and refill the lubricant as often because the seal technology keeps the lubricant where it should be, inside the idler, reducing performance degradation and potential environmental contamination due to leakage.
Preventing the intrusion of dust and other contaminants is especially important for equipment working in dusty, muddy or other harsh environments. Duo-Cone™ seal technology can effectively block these particles, reduce their wear on internal components, keep the idler clean and perform, thereby reducing failure rate and extending maintenance intervals.
Manufacturing process
Casting process
The manufacturing of undercarriage idler involves lost foam casting process, which is an advanced casting technology that can provide precise dimensions and complex geometric shapes.
Combination of wheel body matrix and outer rim
The idler wheel body includes a wheel body matrix and an outer rim, which is made of wear-resistant material and fixedly connected to the wheel body matrix. This structural design makes the guide wheel body have both good impact resistance and good wear resistance.
Material selection
The wheel body matrix material includes ZG270-500, which is a commonly used cast steel material with good mechanical properties and machinability.
The chemical composition of wear-resistant materials includes carbon, silicon, manganese, sulfur, phosphorus, chromium, nitrogen, nickel, molybdenum, titanium, vanadium, etc. These components work together to improve the wear resistance and strength of the outer rim.
Preparation of casting mold
Prepare the wheel body matrix lost foam model, and use the outer wheel rim casting and the wheel body matrix lost foam model to make the wheel body matrix casting mold.
Install the wheel body matrix lost foam model on the outer wheel rim casting to form a double-layer structure assembly, then preheat, load it into the casting sand box filled with molding sand, perform vibration molding, and finally seal and vacuumize to obtain the wheel body matrix casting mold.
Pouring and cooling
Prepare the wheel body matrix pouring liquid, and pour it into the casting mold made of the outer wheel rim casting and the wheel body matrix lost foam model, and form the guide wheel body casting after cooling.
Heat treatment
The idler wheel body casting will be heat treated after formation to eliminate internal stress and further strengthen the material. The heat treatment process includes cooling to a first temperature (820℃～900℃) in the wheel base casting mold, air cooling to a second temperature (300℃～400℃) and keeping it warm (3～12 hours) after taking it out, and then air cooling to room temperature.
Post-processing
The idler wheel casting can also be polished or machined to obtain the final guide wheel body.
Through the above manufacturing process, our undercarriage idler ensures its durability and reliability under high loads and harsh environments. These process steps together ensure the high performance and long life of the guide wheel, enabling it to meet the needs of rigorous engineering operations.

FAQ
01.What is undercarriage maintenance?
02.How long does undercarriage coating last?
03.Why is undercarriage damage?
Damage to the undercarriage of heavy equipment, such as the D11 dozer, can be caused by a variety of factors. Here are some of the most common causes:
1. Rough Terrain:
Driving over rough terrain is one of the top causes of undercarriage damage. When equipment is driven over large holes or depressions, it can cause cracks in the undercarriage, which can lead to leaks. Rough terrain can also include rocks and construction debris that can puncture or knock bolts and other components loose.
2. Weather Conditions:
Driving through snow, mud, or puddles can cause metal parts to rust, causing long-term damage to the undercarriage.
3. Improper Operation:
Using equipment beyond its operating capabilities or making tight turns instead of wide turns can stress the undercarriage, causing premature wear.
4. Neglecting Regular Maintenance:
Failure to regularly inspect the undercarriage of your equipment can cause small problems to escalate into big ones.
