Case-IH® Compatible Narrow Wire Concave Position 1
Optimise your threshing performance with this high-performance aftermarket narrow wire concave. Specifically engineered for Case-IH® early and mid-series Axial-Flow combines, this concave is dedicated for Position 1 fitment. It features a precision-welded intake ramp and a structural integrated extension, providing a high-strength foundation for your threshing system.
Manufactured from premium materials and fully heat-treated, this concave offers superior abrasion resistance compared to standard units. The small wire configuration (30 wires) is designed for efficient separation of small grains, while the single-piece construction eliminates the "flex-fatigue" often seen in bolt-on extension designs. This extended wear solution ensures your threshing assembly stays in top condition for a significantly longer service life.

Expert Maintenance Review
The concaves in the product feeding zone are subject to extreme abrasion as crop material transitions from the feeder house to the rotor. Standard concaves often thin out at the cross-bars, leading to poor threshing and grain loss. We recommend inspecting the cross-bar profile and wire tension during every preventative maintenance check to identify worn components before harvest.
Upgrading to this heat-treated small wire concave is a strategic choice to save money over the life of the machine. The single-piece frame maintains its alignment far better than multi-part versions, ensuring your threshing system remains in top condition. This investment keeps your product feeding system efficient and provides a longer service life in high-yield cropping conditions.
Installation Tip: Ramp Alignment
This concave is designed specifically for Position 1 fitment. When installing, ensure the integrated intake ramp is perfectly flush with the feeder house floor to maintain a seamless product feeding transition. This is the ideal time to check your feeder house slats and front rotor intake flighting for wear to ensure maximum throughput.
