GFM: Top Excavator Bucket Pins Manufacturer in China

What is an excavator bucket pin? Why is it so important?

Among the various key components of an excavator, the excavator bucket pin (also known as the bucket ear pin, connecting pin) is not large in size, but it plays a vital role. The bucket pin mainly connects the bucket ears of the excavator with the boom, dipper rod and other structural parts, and is an indispensable connection hub in the entire bucket movement.

Every time the bucket is excavated, tipped, lifted or unloaded, the bucket pin bears great mechanical pressure and impact load. It can be said that the bucket pin not only determines the flexibility of the bucket movement, but also directly affects the efficiency and operating life of the entire equipment.

If the quality of the bucket pin is not up to standard, it may cause the bucket to loosen, the fit gap to expand, and even the risk of structural fracture, which will bring serious hidden dangers to operation safety and equipment maintenance. Therefore, whether it is a complete machine manufacturer or an equipment maintenance company, when choosing a bucket pin, it should attach great importance to its manufacturing quality, material selection and precision control.

Common types of excavator bucket pins and their application scenarios

According to different models, working conditions and load requirements of the equipment, bucket pins are divided into many types in actual applications. The most common ones are mainly the following categories:

Standard bucket pin

Standard bucket pin is suitable for small and medium-sized excavators, and common specifications include 80×400mm, 90×500mm, etc. This type of bucket pin is suitable for medium-intensity working conditions such as urban infrastructure construction, earthwork excavation, and ditch finishing. It has the advantages of moderate cost, strong compatibility, and easy replacement.

Reinforced bucket pin

Reinforced bucket pin is often used in heavy machinery and equipment. It is designed for high-intensity working environments (such as mines and stone yards). It is usually made of high-strength alloy steel materials, and the surface is quenched to have higher compression and torsion resistance. This type of bucket pin has a long service life and wear resistance, and is suitable for high-frequency, high-load, and high-wear environments.

Non-standard customized bucket pin

For some customers’ customized equipment or imported excavators, standard bucket pins are difficult to fully match, so non-standard customization is required according to drawings, samples or interface requirements. This type of bucket pin emphasizes personalized matching and is generally produced in small batches, especially suitable for OEM/ODM customers.

Special operation bucket pin

Some operating environments (such as deep-sea operations, high-cold areas, and corrosive environments) have special requirements for bucket pin materials and coatings. GFM can provide bucket pins with anti-corrosion treatment, stainless steel or ultra-low temperature materials to meet diverse application needs.
