3.  Compatible 290 Series Bucket Teeth

The parabolic design of the 290 series utilizes natural wear to self-sharpen the point, ensuring "like-new" penetration throughout its service life.

Common profiles available to fit the 158X290 adapter include:

  • X290 (Standard): Excellent general-purpose digging in dirt and clay.

  • X290RC (Rock Chisel): Optimized for high-impact penetration in rocky terrains.

  • X290T / X290WT (Tiger / Twin Tiger): Maximum frost and hard-pan penetration.

4. The Manufacturing Advantage: Premium Lost-Wax Casting

Every component is produced using advanced lost-wax casting (investment casting) to ensure an optimal metallurgical structure, superior yield strength, and maximum resistance to high-impact environments.

By utilizing high-precision molds and strictly controlling the pouring process, we ensure excellent dimensional accuracy right out of the cast. This commitment to manufacturing excellence provides several critical benefits for global procurement managers and heavy-equipment operators:


4.1 Seamless Fitment: 

The tight tolerances achieved during the casting process virtually eliminate the gap between the adapter nose and the tooth pocket, preventing rattling and shifting under heavy loads.

4.2 Pin Protection: 

A secure fit drastically reduces shear stress on the P290 flex pin, protecting against premature breakage in the field.

4.3 Extended Wear Life: 

High-wear alloy steel combined with a dense, defect-free casting structure ensures the forces of digging are distributed evenly, maximizing the lifespan of the entire G.E.T. assembly.


Whether outfitting agricultural machinery or heavy-duty industrial equipment, our strict quality control ensures OEM-level reliability and performance out of the box.
