Product Advantage
This threshing rear concave screen is a high-precision OEM-grade replacement part specifically engineered for World combine harvesters, serving as a core component in the machine’s threshing and grain separation system. Designed for the World 102HP combine harvester series, this rear concave screen plays a pivotal role in separating clean grain from straw and crop debris after the threshing process, directly impacting harvest efficiency, grain loss rate, and final crop quality. Manufactured from premium heavy-duty alloy steel with precision engineering, our World harvester threshing concave sieve is the trusted choice for commercial agricultural equipment distributors, farm maintenance service providers, and large-scale agricultural operators looking to minimize grain loss, reduce field downtime, and optimize harvest performance during peak seasons.
Our combine harvester rear concave screen features an optimized concave structure and precision-engineered sieve hole specifications, which work in tandem with the threshing drum to maximize grain separation efficiency. The design effectively separates clean grain from straw and unthreshed crop material, significantly reducing grain carryover and running grain loss, while ensuring consistent threshing performance across various crop types including rice, wheat, corn, and soybeans.
Crafted from high-grade wear-resistant alloy steel, this grain separation concave screen delivers exceptional impact resistance, abrasion resistance, and structural stability even under continuous heavy-duty field operation. The reinforced weld design prevents deformation and cracking, extending the component’s service life and reducing frequent replacement needs for agricultural operators and maintenance teams.
Manufactured to strict original equipment dimensions, this rear concave screen offers a perfect direct fit for World combine harvesters, eliminating the need for modification during installation. The precision fit ensures optimal clearance between the screen and threshing drum, maintaining consistent separation performance and preventing grain loss caused by improper fitment.

Product Operate Guide
Regularly check whether the screen surface is deformed, cracked, whether the screen holes are blocked, and whether the screen body fits well with the drum.
If there is incomplete threshing, increased loss, or weeds/stems carrying grain, the status of the sieve body should be checked in a timely manner.
At the same time, check whether the fixed clips, U-shaped locks, locking pins and other accessories are loose
