CAT Standard Bucket Tooth J450
The 1U3452RCU is a Caterpillar-compatible standard bucket tooth from the J450 series — CAT's heavy-duty tooth system engineered for large excavators operating in demanding conditions — quarries, heavy civil works, and infrastructure projects. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for large excavators used in heavy construction and quarry operations.
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.
At 13.97 kg, this tooth is built for 35-50 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.
Compatible with: CAT 345, CAT 349, CAT 350, CAT 352. Always verify tooth-to-adapter fitment for your specific machine configuration before ordering. AzuLong's technical team can assist with compatibility confirmation — contact rocky@azulong.com or WhatsApp +86-13777046128.
