Guide Ring for Mechanical Seals

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.

Welded cylinder base is generally a metal plate structure, and the shape is usually round or square. The edge is designed for tight welding with the cylinder, and the central position has holes for the piston rod to pass through, and some have screw holes or positioning pin holes for connecting other components.

Glyd ring for piston is composed of a rubber O-ring and a PTFE ring. The O-ring applies force and the Glyd ring is a double-acting piston seal. It has low friction, no creeping, small starting force, and high pressure resistance. It can be divided into Glyd rings for holes and Glyd rings for shafts.

Retention Knob DIN69872-1988, also known as the DIN pull stud, can be customized to different sizes as customer’s requirement, is a fastening element used for the clamping of tool holders in CNC machines, and it conforms to the German Industrial Standard DIN 69872.

Garbage Truck Lifting Cylinder is a critical hydraulic component in waste collection vehicles, primarily used to drive the lifting and tilting motions of the cargo compartment or compacting mechanism for waste disposal and compression. Typically constructed from high-strength steel, the cylinder offers excellent corrosion resistance and load-bearing capacity, along with a reliable sealing system to withstand harsh operating conditions. Modern designs emphasize energy efficiency, with some models integrating sensors for smart control. Its performance directly impacts the operational efficiency and reliability of sanitation trucks, requiring regular maintenance to ensure long-term durability and stable functionality.

China Hydraulic manifold block from Micro Precision Machinery is the core component of the hydraulic system, primarily comprising valve blocks, hydraulic valves, pipe joints, and other accessories. Its applications predominantly span across sectors such as construction machinery, agricultural machinery and industrial equipment.
