9W8552PT

The 9W8552PT is a Caterpillar-compatible penetration bucket tooth from the J550 series — CAT's high-capacity tooth system designed for mining-class excavators where tooth life and digging performance directly impact production costs. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for mining-class excavators handling the heaviest digging loads.

Penetration Profile — Application & Performance

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.

Material & Durability

At 28 kg, this tooth is built for 50-80 ton class equipment. This heavy-duty tooth is forged from heat-treated alloy steel and finished to HRC 48-58, with the higher hardness range available for demanding rock and mining applications. The increased cross-section provides greater resistance to the bending loads that occur during heavy ripping and prying operations. The heat treatment process is tightly controlled to prevent internal stresses that could cause premature failure under shock loading.

Equipment Compatibility

Compatible with: CAT 365, CAT 374, CAT 385, CAT 390. 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.
