Hydraulic cylinder rods for various equipment

The stem can be cylindrical, conical, or have the shape of a truncated cone. At one end of the rod, an inner sleeve with a threaded hole for mounting the piston is fixed., on another – sealing ring, which the rod is hermetically connected to the cylinder body.

Design features

Cylindrical rod has one end, which is inserted into the hole of the piston of the hydraulic cylinder. O-rings are located on the other end of the stem, which are tightly pressed against the ends of the piston and cylinder body.

Stock, usually, has a screw threaded hole and a conical undercut for centering it in the hydraulic cylinder body. In the lower part of the stem there is a slotted hole for connecting to the stem of the connecting rod. The stem can be threaded or threaded and splined at the same time. In some designs of hydraulic cylinders, the rod may have a cylindrical thread., and at the bottom – slots. This design is used when, when the rod should rotate with the piston.

Where are stems used?

Rods are one of the most important elements of a hydraulic system.. They transmit force from the hydraulic cylinder to the piston. Rods are of two types: brass and steel. Brass rods are more prone to corrosion, Therefore, they are mainly used in systems with a large load.. Steel rod have a long service life, due to its strength and durability. Steel rods are most often used in hydraulic cylinders for lifting and lowering the trawl. Installed in hydraulic cylinders:

• telehandlers,
• hydraulic motors,
• hydraulic pumps,
• and other hydraulic systems.

The rod is the main part in the hydraulic system, it transmits force from the pump rod to the hydraulic cylinder. There is a thread on the stem, therefore it can be fixed in the right place of the hydraulic system. AISI 316L steel is used as a material for the manufacture of the stem., which has high strength and corrosion resistance. Used as wear resistant steel.

Depending on the size and design, the hydraulic cylinder may have either one, or two stems. The rod is one of the most important structural elements of the hydraulic cylinder. It is he who transmits the force from the piston rod and ensures the movement of the piston in the cylinder. The performance of the cylinder depends on the design of the rod.
