1590464U

The 1590464U is a Caterpillar-compatible standard bucket tooth from the J460 series, CAT's updated heavy-duty tooth platform for large excavators, successor generation to the J450 system. Manufactured as an aftermarket replacement by AzuLong Wear Parts, it is designed for large excavators in heavy construction and quarrying.

Standard Profile, Application & Performance

The standard profile provides optimal balance between penetration and wear resistance. It is the most versatile tooth design for everyday excavation work, handling mixed soil conditions including topsoil, clay, and loose gravel. The profile geometry is optimized for self-sharpening wear, as the tooth wears down, it maintains a relatively sharp digging edge rather than going blunt.

Material & Durability

At 22.08 kg, this tooth is built for 35-45 ton class equipment. This heavy-duty tooth is forged from heat-treated alloy steel and finished to HRC 48-58, with the higher hardness range available for demanding rock and mining applications. The increased cross-section provides greater resistance to the bending loads that occur during heavy ripping and prying operations. The heat treatment process is tightly controlled to prevent internal stresses that could cause premature failure under shock loading.
