Technical Parameters
The Roller Assy (code: WD.4MC.32) is a key component engineered for WORLD Combine Harvester models, integrating robust structural design with high-performance materials. Crafted with a wear-resistant shell made from premium forged steel or cast steel, the component undergoes professional heat treatment to enhance durability, while its wheel surface features quenching technology for superior hardness and long-term resistance to friction. Equipped with high-quality bearings and bushings, the assembly ensures smooth and flexible rotation even under harsh working conditions, complemented by a double-layer sealing structure that effectively blocks mud, water, and impurities from infiltrating internal parts. Designed for easy integration, the support roller assembly is fixed to the harvester’s chassis frame via brackets and bolts, forming a stable connection that aligns with the requirements of tracked harvester chassis systems.

Product Uses
As a critical part of the chassis walking system, the Roller Assy plays a pivotal role in supporting the entire harvester’s weight, evenly distributing the load to the tracks for stable operation across various field terrains. It is indispensable for WORLD Combine Harvester users seeking reliable performance during planting and harvesting seasons, ensuring the machine maintains balance and traction even on uneven ground.
The assembly excels in track guidance, preventing deviations and derailments that can disrupt workflow and cause damage to other components. By reducing direct friction between the track and the ground, it extends the lifespan of both the track and the overall walking system, making it a cost-effective solution for farmers and agricultural operations relying on heavy machinery.
In rough or bumpy fields, the Roller Assy acts as a buffer, absorbing impact forces to minimize vibration of the harvester’s body and chassis. This shock absorption function protects sensitive internal parts from wear and tear, ensuring consistent performance and reducing the need for frequent repairs.
Product Operate Guide
Conduct routine checks on the Roller Assy to identify signs of cracks, excessive wear, or oil leakage, as these issues can compromise functionality and lead to more severe damage. Pay close attention to the sealing structure and bearing performance, as even minor defects can affect the component’s ability to protect the chassis walking system.
Follow the manufacturer’s guidelines for lubrication, as proper lubrication of bearings and rotating parts is essential to maintain smooth operation. Use high-quality lubricants compatible with agricultural machinery to reduce friction, prevent overheating, and extend the service life of the support roller assembly.
Regularly remove accumulated mud, straw, and other debris around the Roller Assy to avoid obstruction of rotation. Built-up debris can increase resistance, strain the bearings, and accelerate wear, so keeping the component clean is a simple yet effective way to ensure optimal performance.
If the Roller Assy shows signs of excessive wear, jamming, or structural damage, replace it promptly to prevent track deviation or damage to the harvester’s chassis. Using a genuine support roller assembly ensures compatibility with WORLD Combine Harvester models and maintains the machine’s overall efficiency.
