The boom bucket cylinder, or simply the boom cylinder, is the largest hydraulic actuator on an excavator, located at the excavator's upper arm or boom. The main role of this excavator boom cylinder is to control the movement of the entire boom. In most excavators, there are actually two boom cylinders (the left and right one), which makes the excavator more stable. The more stable it is, the more accurate the operation will be. Therefore, boom excavator bucket cylinders usually control the boom of the entire excavator, not just one part. The excavator boom itself is the part that connects the excavator's body to the arm or stick. The boom excavator bucket cylinder has another very crucial job, and that job is to lift heavy objects. The boom of the excavator, of course, needs to lift heavy objects a lot. Therefore, the excavator needs to be able to lift those heavy objects very smoothly and without any jolts. Thanks to the boom excavator bucket cylinders and their ability to control the hydraulic oil that moves the boom back and forth, the job of lifting heavy objects smoothly and stably is possible.
Located at the top of the excavator, the swing cylinder, or more commonly known as the swing motor, is responsible for controlling the entire rotation of the excavator. Excavators can rotate a full 360 degrees to facilitate work in different directions without the need to move the base. The swing excavator bucket cylinder makes this job possible by controlling the hydraulic flow to rotate the upper structure of the excavator, including the driver's cab and house, relative to its undercarriage. Because the excavator can be rotated completely freely in every direction, working in places where moving the body is not possible becomes possible. This is very crucial in construction work or land reclamation or dredging work in water bodies or rivers. The excavator can easily reach the working part by just rotating its upper part, and the operator does not have to move the entire excavator.
The arm cylinder, or also known as the bucket housing sliding sleeve, is an important excavator hydraulic cylinder responsible for controlling the movement of the arm or stick. It is usually located inside the bucket or the housing of the bucket. The main job of the arm excavator bucket cylinder is to extend and retract the bucket or excavator bucket stick. Thanks to the arm and boom excavator cylinders, the excavator can easily reach the digging or loading position. The operation of the entire excavator is very smooth and precise.
As the name suggests, the bucket cylinder excavator bucket has the job of controlling the movement of the excavator bucket. The bucket cylinder is usually located inside the bucket. The bucket excavator cylinders are responsible for the opening and closing movement of the bucket. The bucket is the part of the excavator that actually digs or scoops material. Thanks to the bucket cylinders, the excavator bucket can perform accurate and delicate movements.
Cylinder body
The practical size from outside of the cylinder body, or shell, of the digging rod. Adopts high-precision steel pipe manufacture, and bore is grinded and seems chrome-plated, which can improve its anti-wear characteristic and anti-corrosion characteristic.
Piston
The piston of the excavator bucket hydraulic cylinder has a seal. It can keep the oil from leaking and make the cylinder move steadily. The size of the piston is appropriate, so it fits perfectly inside the cylinder body, allowing it to move without any problems.
Rod
The rod, also known as the piston rod, extends out of the hydraulic excavator bucket cylinder and is responsible for transmitting the excavator bucket cylinder's motion and force. The digging cylinder's rod is manufactured from high-strength steel, which has great tensile strength and is not simple to break. The surface usually undergoes a plating therapy to resist corrosion and wear.
Seal and Ring
The Hydra excavator bucket cylinder is made up of a piston seal and a rod seal. Their job is to stop the hydraulic oil from leaking and to protect the cylinder from dust and debris. The sealing rings are resilient and should have excellent tensile strength, allowing them to support many years of use.
End Cap / Head

Q: What are the key components of an excavator bucket cylinder?
A: The main components of an excavator bucket hydraulic cylinder include the bucket cylinder rod, which connects to the excavator bucket and extends or retracts the bucket; the bucket cylinder head, a round metal piece at the top of the excavator bucket cylinder that houses the rod sealing mechanism; the cylinder barrel, which contains the hydraulic fluid and piston; the piston, which is located inside the cylinder and is responsible for moving the hydraulic fluid; and the seals and gaskets, which prevent the hydraulic fluid from leaking out of the excavator bucket cylinder.
Q: How does an excavator bucket cylinder work?
A: Excavator bucket hydraulic cylinders work by using hydraulic pressure to move the excavator buckets. When the excavator operator wants to open or close the bucket, hydraulic fluid is pumped into the bucket's cylinder from the hydraulic system of the excavator. This process brings about the movement of the piston in the cylinder. As the piston moves, it causes the bucket to either move up or down, thereby enabling the operations of digging, holding, or releasing of materials.
Q: What are the signs of a damaged excavator bucket cylinder?
A: There are several signs to look out for if an excavator bucket cylinder is damaged or worn out. They include visible leaks from the cylinder, which could be a clear or dark fluid on the ground; reduced or sluggish movement of the bucket; unusual noises such as grinding or rattling; bumping or jerking movements while operating the excavator; and any visible damage to the cylinder such as cracks or dents. If any of these signs occur, it is important to check the excavator bucket cylinder carefully to see if it needs a replacement or repair.
