Excavator Bucket Parts Overview

Main Components
When you look at an excavator bucket, you see several important parts. Each part has a job that helps the bucket work well in tough conditions. Here are the main components you will find:
Cutting Edge: This is the bottom edge of the bucket. It touches the ground first and cuts into the material. The cutting edge uses hardened steel to last longer.
Teeth: These attach to the cutting edge. Teeth break up and loosen soil, rocks, or other materials. You can find teeth in different shapes and sizes for different jobs.
Wear Plates: These plates protect the sides of the bucket. They stop the bucket from wearing out too fast. You can replace them when they get thin.
Side Cutters: These sit on the sides of the bucket. They help the bucket cut through tough ground and protect the corners.
You need all these parts to keep your excavator bucket strong and ready for work. Each part faces different forces and wear, so they need special materials.
Material Needs
You want your china excavator bucket parts to last as long as possible. The right materials make a big difference. Each part needs a certain hardness and strength. The table below shows some common materials and where you might use them:
Material Type | Hardness (HB) | Application Area |
---|---|---|
Hardox 400 | 400 | General construction |
AR400 | 400 | Mining and quarrying |
ASTM A572 Grade 50 | 250-350 | Structural applications |

You should think about what you will dig up. Rocks need tougher parts. Muddy or wet ground may need a different design. The right hardness helps your bucket carry heavy loads without bending. Harder materials mean less downtime and better performance on the job site. When you choose the best materials for each part, your excavator bucket works better and lasts longer.
China Excavator Bucket Parts Materials

Bucket Shell Materials
Excavator bucket shells need to be strong and dependable. Most bucket shells in China use high-strength steels. These steels give a good mix of strength, light weight, and easy welding. The table below lists the main materials and their features:
Material | Properties |
---|---|
ASTM A572 Grade 50 | High strength, low alloy, lightweight, easy to weld |
AR400 | Abrasion resistant, hardness of 400 HB, excellent wear resistance |
AR500 | Abrasion resistant, hardness of 500 HB, superior wear resistance |
AR400 and AR500 are great at stopping wear. ASTM A572 Grade 50 makes a bucket shell that is lighter but still strong. These materials help buckets do hard jobs without being too heavy. Picking the right shell material helps your bucket work better and need less fixing.
Tip: YNF Machinery makes bucket shells from these strong materials. You get parts that last longer and work well.
Bucket Teeth Materials
Bucket teeth do the hardest work on excavator buckets. You need teeth that can break rocks, dig dirt, and not wear out fast. The most used bucket teeth materials in China are manganese steel and alloy steel. The table below shows why these materials are good:
Material | Properties | Applications |
---|---|---|
Manganese Steel | Good toughness, work hardening, improved wear resistance under impact loads | Earthmoving, mining, adaptable to various hardness |
Alloy Steel | Enhanced strength, hardness, wear resistance due to alloying elements | Suitable for high hardness, abrasive materials |
Manganese steel is the best pick for bucket teeth. It gets harder as you use it, so it lasts longer. Alloy steel teeth are heat-treated to make them stronger and tougher. This makes them good for digging hard things. Manganese steel teeth are usually 48-52 HRC in hardness and have an impact value over 15 J. These features help bucket teeth last in rough jobs.
YNF Machinery gives you bucket teeth made from strong manganese steel. This keeps your excavator buckets sharp and tough.
Pins and Bushings
Pins and bushings join moving parts in excavator buckets. They must take heavy loads and move all the time. The best materials for these are AISI 4130, AISI 4140, ETD-150, and 45# carbon steel. The table below compares AISI 4130 and AISI 4140:
Property | AISI 4130 | AISI 4140 |
---|---|---|
Carbon Content | 0.28-0.33 wt.% | 0.38-0.48 wt.% |
Hardness | Lower than 4140 | Higher due to more carbon |
Strength | Good for moderate applications | Superior for high strength |
Weldability | Good | Poor |
Fatigue Resistance | Moderate | Higher due to better strength |
Longevity | Suitable for various uses | Preferred for demanding uses |
AISI 4140 gives better fatigue resistance and lasts longer. ETD-150 and 45# carbon steel are also tough and strong. Makers shape these parts very carefully so they fit well. Some bushings use nitronic steels or Hadfield manganese steel for extra wear resistance.
Note: YNF Machinery has pins and bushings made from these top materials. You get parts that fit right and last longer in your buckets.
Excavator Bucket Wear Parts
Wear parts protect your bucket from getting damaged. These include wear plates, side cutters, and adapters. The main materials for these are high-strength steel, high chromium cast iron, and low carbon alloy steel. The table below shows their features:
Material Type | Properties | Wear Rate Influences |
---|---|---|
High-strength steel | Hardness, toughness, resistance to abrasion | Type of material being excavated, digging technique, frequency of use in abrasive environments |
Cast iron | Hardness, toughness, resistance to abrasion | Type of material being excavated, digging technique, frequency of use in abrasive environments |
You want wear parts that can handle rocks, sand, and other hard stuff. High chromium cast iron is very hard and resists wear. Low carbon alloy steel is tough and strong. These materials help buckets last longer and stop breakdowns.
