description

This 819906012 center tooth assembly is cast from high-chromium alloy, treated by quenching and tempering. The tip reaches high hardness while the root maintains good toughness for balanced wear resistance and impact resistance, resisting chipping and fracture. The general-purpose pointed tooth profile reduces penetration resistance for smooth feeding and higher loading efficiency. The matched tooth adapter distributes impact stress and protects the tooth base from direct wear. Supplied as a complete assembly with all pins and retaining clips for direct installation. Each batch passes visual inspection and hardness sampling test to eliminate casting defects such as blowholes and shrinkage cavities. Suitable for earth, sand and gravel mixed materials, it is a high-frequency wear part for loader buckets.

- Alloy casting and tip quenching, longer service life than ordinary carbon steel teeth
- Optimized pointed shape for low digging resistance and faster loading
- Complete assembly with all pins and clips included for immediate installation
- Tooth adapter absorbs shock and reduces wear on bucket tooth base
- Balanced toughness, less brittle fracture under normal gravel impact
- Widely circulated spare part with sufficient stock for quick on-site repair

FAQ 

Q：Can dull center teeth keep working?
A：It can run temporarily, but digging resistance rises and cutting edge bears extra load. Replacement is recommended in time.

Q：Can this center tooth be used on rock bucket?
A：This is earth-type tooth with limited impact resistance. It may break easily for large rocks. Heavy-duty rock teeth are required.

Q：Can I buy pins or circlips separately?
A：Yes, they are standard spare parts. Make sure circlip is locked properly to prevent tooth falling off under vibration.

Q：What notes for tooth installation?
A：Clean sand and rust inside tooth base, align adapter holes, drive pin fully and confirm circlip is seated.

Q：Why do bucket teeth break frequently?
A：Common causes are prying hard boulders, rock striking, deformed tooth base or excessive fit clearance, which concentrates impact on tooth root.

Q：What to inspect when receiving new tooth assembly?
A：Verify part number, check casting cracks and blowholes on tip and root, test fit with tooth base and confirm pin holes align.
