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.

Hydraulic Nut for Hydraulic Cylinder: Hydraulic Nut is mainly used in mobile machinery hydraulic cylinders, industrial engineering hydraulic cylinders, marine engineering hydraulic cylinders, energy technology hydraulic cylinders etc. 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, which has many years experience. Hope to establish business relationship with you!

Welded cylinder base for lock valve is one of hydraulic cylinder parts, it's the important part to ensure the safe and stable operation of the system. It is often used in engineering machinery, metallurgical equipment, ships and other occasions that need to accurately control the position of hydraulic actuator or maintain pressure.

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.

Oil seal RS series, also known as the piston rod one-way sealing ring, is composed of an anti-wear filled polytetrafluoroethylene PTFE ring and an O-type rubber sealing ring. The O-type ring provides elasticity to compensate for the wear of the PTFE step ring and only has a one-way sealing effect.

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.
