Parlec retention knob

The material of the T3A hydraulic cylinder balance valve block; Q355D forged, 20# steel, GGG50, etc. Each piece is subjected to flaw detection testing to prevent oil leakage and oil channeling in the hydraulic valve block.

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.

Crane telescopic hydraulic cylinder is a device that uses a hydraulic system to achieve telescopic function, and is mainly used for crane boom telescopic. It consists of an outer cylinder, an inner cylinder, a piston, a seal, a tie rod, and a hydraulic oil pipeline. The pressure of the hydraulic oil drives the piston to move, thereby driving the inner cylinder and the tie rod to telescope, realizing the telescopic function of the crane arm.

ZZ-00336 Precision Combination Modular Vises are made of high quality alloy steel carburized, surface working hardness HRC58-622, Parallelism 0.0005mm/100mm, verticality 0.005m3. With a removable base, fixed jaws, movable jaws, fast tightening, easy operation. Widely used in machining center on precision machine tools.

As an important fitting of hydraulic cylinders, the assembly cylinder base is used to seal the bottom of the hydraulic cylinder, connect the cylinder with external equipment, and fix the piston assembly. For example, in the hydraulic cylinder of engineering machinery, the assembly cylinder base ensures the smooth movement of the piston in the cylinder block, to ensure the normal operation of the entire hydraulic system.

Retention Knob JIS B6339-1986, as stipulated by the Japanese Industrial Standards, are pull studs used in CNC machines to connect tool holders and draw bars, securely pulling the tool holders into the spindle. They are also known as retaining screws or pull knobs. Pull Studs can be customized to different sizes as customer's requirement.
