Excavator Swing Hydraulic Cylinder pushes the piston to move through the pressure of the hydraulic oil, thereby driving the upper body of the excavator to rotate left and right relative to the lower chassis. It is generally installed in the slewing mechanism of the excavator and works in conjunction with other components to enable the excavator to flexibly change the working direction and angle in various construction scenarios.

Crane counterweight hydraulic cylinder is an important device that realizes crane balance through hydraulic transmission mechanism. It is mainly composed of cylinder body, piston, piston rod, sealing element, oil filter, hydraulic pipeline and oil tank. The working principle is based on Pascal's law, that is, in a closed container, pressure is transmitted to every point in the liquid, and the pressure acting on the liquid is proportional to the area. When the crane is lifting, the hydraulic pump presses the oil into the cylinder, causing the piston to rise, thereby increasing the hook height. When the load of the crane increases, the oil inside the cylinder will be compressed and the piston will drop, thus achieving the balance of the crane.

The ER tool holder is a commonly used tool holding device in machine tool processing, mainly used for fixing and clamping straight shank tools, such as drills and milling cutters, it's also called milling chuck arbor.
Tool holder can be customized to different sizes as customer's requirement.
Its common specification includes BT30, BT40, BT50 etc.

Hydraulic bushing is an economic component in hydraulic cylinders and hydraulic equipments. It could be as the start or end of the installation distance, and mainly has the supporting function in hydraulic equipments.
It's important to select the suitable hydraulic bushing, which could get better performance for the equipments.

Customized Welded cylinder Base, also known as welded cylinder base end, is specially processed as customer's drawing and special requirement. The main function is to form an enclosed space with the cylinder to accommodate the hydraulic oil and piston assembly, while ensuring the tightness of the hydraulic cylinder, preventing oil leakage, and providing support for the piston rod and the whole hydraulic cylinder to ensure its stable work, which is similar function as common welded cylinder base.
