61QA-31310U

The 61QA-31310U is an aftermarket replacement standard tooth compatible with Hyundai R380/R430 excavators — an aftermarket replacement tooth for Hyundai R380/R430 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 14.56 kg, this tooth is built for 38-43 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.
