Product Features

Aggressive Leading Edge Design

The improvement in productivity from the penetration of cutting through tough digging conditions (soil compacting, gravel, and rock) with the sharp edges of the 7J 9552, 9W8552 CAT J550 Digging Bucket Teeth is also attributed to the reduction in energy expenses. The improvement in productivity from the penetration of cutting through tough digging conditions (soil compacting, gravel, and rock) with the sharp edges of the 7J 9552, 9W8552 CAT J550 Digging Bucket Teeth is also attributed to the reduction in energy expenses.

Optimized Tooth Profile

This set of bucket teeth is able to excavate better because of the reduced resistance as they are designed to be sleek and literally streamlined. These assist highly torqued machines to lower the stress on the bucket aided by better movement and fuel efficiency, slower cut tight fuel consumption, and torque expenditure, leading to overall better performance of the machine at heavy-duty.

High Wear Resistance

The premium alloy steel teeth with class HRC 48-52 are guaranteed to efficiently outlast others' relentlessly demanding work environments, with these featuring the capabilities to withstand lower temperatures and even retain the heat at a higher abrasion with advanced surface treatment.

Greater Nose Strength & Durability

Teeth have the great feature of preventing breakage under high pressure and gradual build-ion of high temperatures during the excavation process, these teeth are built with improved nose structure providing better fatigue strength and having a higher withstand towards impact, making these teeth ideal to work with not so forgiving rock and hard soil surfaces.

Secure Attachment System

Features 1U1558 pin and 8E5559 sleeved retainer. The bucket teeth provide a secure, vibration-resistant fitting that reduces loosening during operations. The locking mechanism improves stability, increases safety, and reduces machine downtime.

Product Advantages

Prolonged Life Span

Incorporating heat resistant performance alloy materials along with differential heat treatments significantly increases a product's wear resistance, increasing service life while lowering frequent part replacements.

Improved Excavation Efficiency

Increased productivity is achieved with the deeper penetration profile as it allows for quicker material entry and reduced digging resistance. Therefore, increased work efficiency is achieved at reduced energy consumption.

Buckets Teeth High Impact

These bucket teeth are impact and shock resistant because they are made from high-strength forged steel and processed with advanced heat treatment, ensuring toughness in rigorous excavation and mining activities.

Use Checklist

Check Compatibility

Before fitting the 7J9552, 7J-9552, CAT 9W8552 J550 Digging Bucket Teeth, ensure that they are compatible with your machine's adapter and lock system.

Use Correct Pins & Retainers

Always use the correct 1U1558 pin and 8E5559 retainer for secure and stable attachment, avoiding unintentional breaks in connection.

Control Load

Bucket teeth are liable to wear down or get damaged when digging beyond the recommended excavation capacity.

Keep An Eye on Wear

Inspect and replace worn down teeth regularly, or else the fuel economy will suffer and the bucket structure will get damaged due to uneven digging.

Abide By Instructions

The manufacturer guidelines concerning installation, use, and maintenance should always be followed as they enhance performance and durability.

FAQ

Q: What machinery can use these bucket teeth?

A: These bucket teeth were made for Caterpillar J550 series excavators, loaders, and backhoes. They also work with other makes such as Komatsu, JCB, John Deere, Bobcat, and others so long as the J550 tooth system is utilized.

Q: What type of tasks are these bucket teeth best for?

A: These are best suited for rock and gravel, compacted soil, and general digging. Common in Construction, Mining, and Earthmoving industries.

Q: Are these bucket teeth sold as a set or individually?

A: You can purchase them individually or in bulk, whichever your situation deems practical. Reach out to us regarding bulk purchase pricing.

Q: What is the procedure for installing these bucket teeth?

A: Clean the adapter portion and ensure no debris is left behind.
Pass the 1U1558 pin through the tooth and the adapter portion.
Secure using the 8E5559 sleeved retainer.
Ensure tight fit prior to using.
