1U3302RCU

The 1U3302RCU is a Caterpillar-compatible standard bucket tooth from the J300 series — CAT's tooth system for the 14-18 ton class, bridging compact machines and the mainstream J350 platform. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for mid-size excavators and mid-size wheel loaders.

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 5.5 kg, this tooth is built for 14-18 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.
