The 330 Bucket Teeth and 158X330 Adapter Assembly are critical Ground Engaging Tools (GET) designed specifically for 30-ton class heavy-duty excavators. As the direct contact point between the bucket and the earth, this assembly protects the bucket lip from severe wear while significantly enhancing digging penetration and operational efficiency. Manufactured from premium alloy steel, it delivers outstanding stability and durability in the harshest working environments.

Formulated with special low-carbon alloy steel to maximize resistance against severe abrasion.
The internal structure retains excellent toughness, preventing breakage and snapping even when operating in hard rock conditions.
Engineered with high-precision molds to ensure a seamless connection between the tooth and the 158X330 adapter, eliminating vibration and pin stress.
The self-sharpening design reduces digging resistance, which lowers fuel consumption and extends the replacement cycle, ultimately reducing your total cost of ownership.

We employ advanced manufacturing techniques to ensure every piece meets strict international standards:
Utilizing Lost Wax Casting (Investment Casting) or advanced forging processes to guarantee dimensional accuracy and structural integrity.
Subjected to rigorous Quenching and Tempering processes, achieving a surface hardness of HRC 48-52 while maintaining a ductile core.
Removes surface scale and impurities, improving surface finish and fatigue resistance.
Coated with eco-friendly, anti-corrosive paint (customizable colors, typically yellow or grey) to prevent rust during sea freight and warehousing.
Mining Operations: Ideal for stripping hard rock, ores, and coal seams.
Heavy Construction: Used in foundation excavations for highways, railways, and bridges.
Quarries & Sand Pits: High-strength loading and digging of gravel and crushed stone.
Earthmoving: Highly effective for handling frozen soil, hardpan, and mixed construction debris.
To ensure the secure and safe operation of the assembly, we recommend purchasing the following standard components:
Tooth Pin: Secures the bucket tooth to the adapter.
Retainer / Lock: Prevents the pin from backing out under heavy vibration.
Bucket Lip Shrouds: Provides additional protection for the bucket's leading edge.

When sourcing in bulk, please consider the following crucial points:
Double-check the gap size and bevel thickness of the 158X330 adapter to ensure it perfectly matches your excavator's bucket lip.
Select the correct tooth profile (e.g., Standard, Rock Chisel, or Penetration) based on your specific working conditions.
Always request material composition certificates and hardness test reports (HRC value) from the supplier to guarantee quality.
Ensure the supplier uses export-standard packaging (e.g., fumigation-free wooden pallets) capable of bearing heavy loads and preventing transport damage during long-distance ocean shipping.
Lihuacasting is dedicated to supplying premium investment casting components to the global market. By controlling the entire manufacturing process from pattern creation to final heat treatment in-house, we guarantee consistent quality, competitive factory-direct pricing, and reliable delivery for bulk B2B orders.
