Product Features
High quality products
Original factory production standard
Wear resistance
The wheel rim of Komatsu track roller ass'y has been specially quenched, with high hardness and strong wear resistance, which can effectively reduce the wear during the operation of the track and extend the service life.
Good sealing
Equipped with high-performance sealing devices, such as floating seal rings and floating seal rubber rings, which can effectively prevent lubricating oil leakage and muddy water intrusion, and ensure good lubrication and working environment of internal bearings and other components.
Strong corrosion resistance
The material and surface treatment of track roller ass'y make it have good corrosion resistance and can adapt to various harsh working environments, including humid, dusty, acid and alkali and other corrosive environments.
Precise track guidance
The flange design on both sides of the wheel body can accurately clamp the track chain rail to prevent the track from slipping laterally and ensure that the bulldozer travels stably in the predetermined direction.
Low rolling resistance
The structural design and manufacturing process of the track wheels make their rolling resistance small, which can reduce energy loss during the bulldozer's travel and improve fuel efficiency.
Adapt to complex terrain:
Track roller ass'y has good flexibility and elasticity, can adapt well to terrain changes on uneven ground, and ensure the driving stability and passability of the bulldozer.
Product Advantages
High cost performance
Aftermarket price, original factory standard
Good heat dissipation
Komatsu track roller ass'y can effectively dissipate heat during operation to avoid excessive heat generated due to long-term operation that affects its performance and life.
Good impact resistance
Our track wheels can withstand the impact force transmitted by the tracks, and have a good buffering effect on the impact of the ground during the driving and operation of the bulldozer.
High-precision manufacturing
Our factory uses advanced manufacturing technology and equipment to ensure the dimensional accuracy and geometric tolerance of the track rollers, making them more precisely matched with the tracks and other components.
High reliability
Our track roller ass'y carries out original factory quality inspection and test verification, has high reliability, can run stably in long-term work, and reduces downtime.
Use case examples
our casey
Large-scale open-pit coal mining
In a large open-pit coal mine, the roads are rugged and filled with coal blocks and rock fragments of various sizes. With its solid structure, the Komatsu track roller ass'y stably supports the weight of nearly 50 tons.
Even when it is frequently driven on uneven roads for a long time and is hit by coal blocks and rocks, it can still maintain good operating conditions. After a large-scale coal seam mining, the mining area needed to be quickly leveled for subsequent operations. The D275A worked continuously for several hours, and the supporting wheels were fault-free throughout the process, ensuring the efficient operation of the equipment.
Mountain Highway Construction
The terrain in a highway construction project in a mountainous area is complex, with steep slopes and mostly hard rock geology. The work task is to clear the site and flatten the roadbed.
When the D275A bulldozer is climbing, our track roller ass'y provides strong grip and stable support, allowing the equipment to climb steadily at a 30-degree climbing ability and maintain balance on the inclined slope. Facing the sharp protrusions on the rocky ground, the wear-resistant characteristics of the track rollers effectively reduce wear and ensure that the equipment can be constructed stably for a long time under complex road conditions in mountainous areas.
Water conservancy construction
At a water conservancy dam foundation construction site, the soil is relatively soft and contains a lot of water, which is prone to sinking. The sealing design of the track roller ass'y effectively prevents the intrusion of muddy water and avoids damage to internal parts due to corrosion and wear.
On wet and soft ground, the track rollers evenly distribute the weight of the equipment, reduce the ground pressure, reduce the risk of equipment sinking, and ensure that the equipment can continue to operate in harsh construction environments.

F A Q
FAQ
01.How long is the replacement period for the Komatsu D275A track roller ass'y?
02.What is the structure of the Komatsu D275A track roller?
03.How to determine whether the Komatsu D275A track roller is damaged?
Visual inspection: Check the surface of the roller for obvious wear, scratches, deformation or cracks. If the wheel surface is severely worn, resulting in a significant reduction in diameter, or there are visible cracks, this indicates that the roller may be damaged.
Operation status: When the bulldozer is operating, if the crawler is unstable, stuck, or deviates, or if the machine makes abnormal noises during operation, especially sharp friction sounds related to the position of the track rollers, it is likely that the track rollers are faulty. For example, if the internal bearing of the track roller is damaged, the wheel body will not rotate smoothly, which will affect the operation of the crawler.
Sealing inspection: Check whether there is any oil leakage at the seal of the track roller. If the seal fails, mud and water and other impurities can easily enter the track roller, accelerating the wear of parts and causing damage to the track roller. If oil seepage is found at the seal, it needs to be handled in time.
