"The bucket teeth are clearly labeled 'super wear-resistant,' so why did they wear out and fail after only one month?" "The newly replaced wear-resistant plates cracked after just one heavy load operation?"—These are the most common customer complaints in the engineering equipment parts industry. In fact, most of the time it's not that the product quality is substandard, but rather that the selection process went wrong! Especially these three frequently encountered pitfalls, which 90% of engineering teams have fallen into. Reading this guide to avoid these pitfalls will save you money and minimize delays.

Many construction teams, seeking convenience, assume that "loader and excavator bucket teeth look similar" and directly purchase generic replacements—this is a common mistake. It's crucial to understand that loaders primarily operate by shoveling and compacting, requiring bucket teeth to withstand continuous surface loads, emphasizing root bending strength. Excavators, on the other hand, primarily dig and break, subjecting their bucket teeth to high-frequency impact loads, necessitating a wear-resistant layer concentrated at the tooth tips.

Mixing generic components leads to "double failure": loader using excavator bucket teeth results in insufficient root strength, making them prone to breakage; excavator using loader bucket teeth causes rapid wear on the tooth tips, reducing a component's potential 6-month lifespan to 1-2 months. It is strongly recommended to verify the equipment model and operating parameters during procurement, selecting "machine-specific wear-resistant parts," such as excavator-specific bucket teeth or loader-customized wear-resistant teeth, to ensure wear resistance precisely matches the load requirements.

"Why are bucket teeth from small factories half the price of brand-name parts when they look the same?" The answer lies in the supplier's qualifications. Reputable wear-resistant parts manufacturers must be ISO9001 quality system certified, with clear testing reports on wear-resistant layer thickness and material composition (such as high-manganese steel and alloy wear-resistant layer ratio). Small workshops, in order to reduce costs, will reduce the thickness of the wear-resistant coating (from 8mm to 3-4mm) and adulterate the materials (using recycled scrap steel).

From a long-term cost perspective, products from small workshops are completely uneconomical: brand-name bucket teeth may have a higher unit price, but their service life is much longer; small-factory bucket teeth may seem cheaper, but they may need to be replaced in a short period. Considering the downtime for replacement, the labor costs, and the losses due to delays, "the total cost of using small-factory parts three times equals the long-term cost of using one brand-name part," and there is also the risk of safety accidents due to component breakage. When purchasing, it is essential to verify the supplier's production qualifications, testing reports, and customer case studies, and choose a reputable supplier with an industry track record.
