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.

CHM Universal Vises are composed of two parts: a precision tool flat-nose pliers and a turntable base. With the help of a graduated turntable, it can move within a 360° range on the horizontal plane and tilt 45° on the vertical plane. It can be used for precision grinding machines, milling machines etc. for straight, inclined surface or angular surface machine and drilling.

Qingdao Micro Precision Machinery Co., Ltd. is a professional manufacturer and supplier that mainly produces hydraulic parts and hydraulic cylinders with reliable quality and stable delivery.

Retention knob MAS403-1982 is an important component used to connect the machine tool spindle and the tool holder, it's also called CNC pull stud. Its primary function is to fix the tool holder onto the machine tool spindle through tensile force, ensuring the stability and safety of the cutting tool during high-speed rotation.
Pull Studs can be customized to different sizes as customer's requirement.

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.
