61NA-31310

The 61NA-31310 is an aftermarket replacement standard tooth compatible with Hyundai R290/R320/R360 excavators — an aftermarket replacement tooth for Hyundai R290/R320/R360 large excavators. Manufactured by AzuLong Wear Parts to match OEM specifications for direct bolt-on replacement.

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 12.82 kg, this tooth is built for 29-36 ton class equipment. Manufactured from heat-treated alloy steel with HRC 48-52 hardness, this mid-range tooth is calibrated to match OEM weight and dimensional specifications. The controlled heat treatment achieves consistent hardness distribution from the tip — where abrasion resistance is critical — through to the base, where toughness prevents cracking under impact. Each tooth is inspected for dimensional accuracy before shipping.
