Hydraulic cylinder parts
Cylinder barrel
The main function of the cylinder body is to contain cylinder pressure. The cylinder barrel is mostly made from honed tubes. Honed tubing is used for hydraulic cylinders that do not need further ID processing. The surface finish of the cylinder barrel is typically 4 to 16 micro inch.
Honing process and Skiving & Roller burnishing process are the two major processes for manufacturing cylinder tube. The piston reciprocates in the cylinder. The cylinder barrel has features of smooth inside surface, high precision tolerance, durable in use etc.
Cylinder base or cap
The cap encloses the pressure chamber at one end. It is connected to the body by means of welding, threading, bolts, or tie rod.
Cylinder head
The head is to encloses the pressure chamber from the other end. It contains an integrated rod sealing arrangement or the option to accept a seal gland.
Piston
The piston separates the pressure zones inside the barrel. It is machined with grooves to fit elastomeric or metal seals and bearing elements.
Piston rod
The piston rod is a typically a hard chrome-plated piece of cold-rolled steel which attaches to the piston and extends from the cylinder through the rod-end head. The piston rod connects the hydraulic actuator to the machine component doing the work. This connection can be in the form of a machine thread or a mounting attachment. The piston rod is highly ground and polished so as to provide a reliable seal and prevent leakage.
Seal gland
The seal gland area of the cylinder head that is fitted with seals to prevent the pressurized oil from leaking past the interface between the rod and the head. The advantage of a seal gland is that it allows for easy removal and seal replacement.
The Hydraulic Cylinder seal gland contains a primary seal, a secondary seal or buffer seal, bearing elements, wiper or scraper and static seal. In some cases, especially in small hydraulic cylinders, the rod gland and the bearing elements are made from a single integral machined part.
