9W8552PTU Product Details

The 9W8552PTU 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 an 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 30.43 kg, this tooth is built for 50-80 ton class equipment. Among the largest teeth in the product range, this tooth is cast from alloy steel and heat-treated to the upper end of the HRC 48-58 scale. At this size class, heat treatment consistency matters most, premature failure means equipment downtime. Full quality documentation is provided per batch.
