CAT Penetration Bucket Tooth J350
The 1U3352PTU is a Caterpillar-compatible penetration bucket tooth from the J350 series — one of the most widely used tooth systems in the global construction equipment market, the industry standard for mid-size excavators. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for mid-size excavators — the most common class on construction sites.
The penetration profile features an aggressive, narrow tip geometry that concentrates digging force for maximum ground-breaking ability. This makes it the preferred choice for hard-packed soil, dense clay, and moderately rocky conditions where standard teeth may struggle to achieve adequate depth. The sharper tip also reduces bucket crowd force requirements, decreasing stress on the excavator hydraulic system.
At 11.3 kg, this tooth is built for 15-25 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 320, CAT 323, CAT 325, CAT 330. 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.
