Where are the Bushings Distributed in the Excavator?
Bushings are an essential part of an excavator and are vital to improving operational efficiency and extending the life of the machine. They are skillfully installed in high stress areas such as booms, dipper & stick, buckets etc. to minimize friction and wear between moving metal parts. It is also able to withstand high loads and harsh working conditions, and can be easily replaced when damaged.
1. Booms
The boom is the main support part of the excavator’s work unit, and it realizes the lifting and lowering motion through the expansion and contraction of the boom cylinder. Its function is to change the working height and position of the bucket to adapt to different digging depths and operational requirements.
- Bushing Type: bronze bushings, self-lubricating bushings.
2. Dipper & Stick
Dipper & Stick is connected with the movable arm and realizes the telescopic movement through the telescopic movement of the bucket cylinder. Its length and angle can change the working range and digging angle of the bucket, so that the bucket can reach different positions for digging and loading.
- Bushing Type: steel bushings
3. Buckets
Buckets are in direct contact with materials and are used for digging, loading and transporting materials. It has different shapes and sizes for different operational needs, such as positive bucket, backhoe bucket, pulling bucket, grabbing bucket, etc., which are more common.
- Bushing Type: flanged bushings, excavator bucket bushings
4. Crawler
Crawler consists of track plate, track pin, track link and so on, it is the traveling part of excavator. Its good grounding specific pressure and adhesion enable the excavator to travel on various complicated terrains.
- Bushing Type: steel bushings
5. Guide Wheel
The guide wheel is located at the front end of the track, and its function is to guide the direction of movement of the track so that the track can travel along the correct path. It also adjusts the tension of the track to prevent the track from being too loose or too tight.
- Bushing Type: steel bushings
6. Supporting Wheel
Supporting wheel is an important part in the track traveling device, its function is to support the weight of the excavator and distribute the weight evenly on the tracks to reduce the wear and deformation of the tracks.
- Bushing Type: steel bushings
7. Hydraulic Cylinder
Hydraulic cylinder is an actuating element in a hydraulic system. It converts the pressure energy of hydraulic oil into mechanical energy to drive the moving arm, bucket rod, bucket and other parts to carry out linear reciprocating motion.
- Bushing Type: bronze bushing, self-lubricating bushing

Common Excavator Bushings for You
Steel bushings are made of high-strength steel as the base material. After quenching and other heat treatments, the hardness and wear resistance are improved. They are the core choice for heavy-load parts of excavators.
They have outstanding load-bearing capacity and can withstand the huge impact force at the hinges of structural parts such as booms and dippers. At the same time, they have strong anti-deformation ability and are suitable for parts that need to transmit torque, such as the bushings of crawler drive wheels and guide wheels.
Graphite Impregnated Bronze Bushings
This type of bushing is based on bronze and is evenly impregnated with solid graphite as a lubricant. It combines the wear resistance of bronze with the self-lubricating properties of graphite, making it an ideal choice for low-load and inconveniently lubricated parts of excavators.
At locations where it is difficult to frequently add grease, such as the hinge point between the boom and the frame and the bucket pin, graphite can automatically precipitate during friction to form a lubricating film, reducing the frequency of maintenance.
The self-lubricating bushing adopts a composite structure: steel backing layer, sintered copper powder layer and PTFE lubricating layer, so it has a long-term lubrication mechanism and does not require additional lubricant.
In the slewing bearings of the excavator, hydraulic cylinder earrings and other parts that need to operate continuously and have narrow spaces, it can avoid dry friction caused by grease loss in traditional lubrication methods.
Bimetallic bushings are usually backed by high-strength steel and composited with low-friction materials such as babbitt alloy and copper alloy on the surface. They combine the impact resistance of steel with the friction reduction of the surface and are suitable for key parts of excavators with high loads and low speeds.
At the bushing of the track roller, the steel back can withstand the radial pressure caused by the weight of the whole machine, and the surface alloy reduces the friction and wear with the wheel axle.
Bronze bushings are widely used in low-load and stable lubrication parts of excavators due to the good wear resistance, thermal conductivity and anti-seizure properties of copper alloys.
In the piston rod guide sleeve of the hydraulic cylinder and the pin sleeve of the bucket connecting rod, the friction reduction of bronze can reduce the wear of the mating parts (such as the piston rod and pin).
Flanged Bushing
The flanged bushing adds a radial flange structure on the basis of the cylindrical body. The flange can play an axial positioning role to prevent the bushing from axial movement in the mounting hole, and adapt to the connection parts of the excavator that need axial fixation.
At the connection hole between the crawler frame and the supporting wheel and the bottom hinge of the boom hydraulic cylinder, the flange can withstand the axial force, ensure the relative position of the bushing and the mounting hole is stable, improve the connection stability of the overall structure.
