An essential base for bucket teeth – a durable center weld-on adapter, compatible with the popular CATERPILLAR J250 system. It is designed to be welded onto a 30 mm thick cutting edge. Made from high-grade cast steel, it is resistant to cracking and impact, providing a durable and solid mount for J250 teeth. This is a critical structural component that transfers digging forces from the bucket to the tooth.

| Brand | Type / Series / Model |
|---|---|
| Universal | Any machine (Caterpillar, JCB, Komatsu, Case, Bobcat, Kubota, John Deere, ESCO, Hensley, H&L) with a 30mm lip and J250 tooth system. |
The list above is for reference. It is crucial to verify the tooth system (J250) and lip thickness (30 mm).
Adapter installation requires welding. Welding work on structural attachments should only be performed by a certified welder, following proper procedures (pre-heating, correct welding consumables) to prevent cracks and ensure the full strength of the joint.
The adapter is the base that mounts the tooth to the bucket's cutting edge. It is a critical component that transfers the entire digging force from the bucket to the tooth. Damage or wear makes work impossible and leads to lost teeth.

J250 is the size designation for a popular CATERPILLAR tooth system. It is one of the smaller sizes, commonly used on backhoe loaders, mini excavators, and small loaders (approx. 7-15 ton class).
2. Will a J300 tooth fit this adapter?No. The CAT J-Series tooth systems are not interchangeable between sizes. This J250 adapter will only fit J250 teeth (e.g., 1U3252) and requires J250 hardware (9J2258/8E6259).
3. Why must I pre-heat the adapter before welding?Adapters are made of cast steel with a high carbon content, which gives them hardness but makes them susceptible to cracking during welding. Pre-heating slows down the cooling process of the weld, reduces stress, and prevents the formation of brittle structures in the metal, which is crucial for the joint's durability.
