How are hydraulic cylinders made?
A hydraulic cylinder, sometimes also known as a linear hydraulic motor, is a mechanical actuator capable of creating linear motion, used wherever great strength and motion are required. Depending on whether the cylinder is single-acting or double-acting, this motion can go in one direction or two. A
hydraulic cylinder supplier. will provide cylinders to manufacturers in a vast variety of different industries, including construction, agriculture, and mechanical engineering. Cylinders are used in all manner of machinery and applications including excavators, bulldozers, conveyor belts and production lines, feeding lines, and transport equipment.
Hydraulic cylinders are made up of several main components: the barrel and the piston. A cylinder bot-tom and a cylinder head close the respective sides of the cylinder, with the piston rod exiting through the head. The base is welded (or screwed) to the barrel. It’s the pressurised fluid (usually oil) within the cylinder that creates the force that makes cylinders a key part of hydraulics systems.
Hydraulic cylinders are only one element of whatever machinery or application they are used in – but they are always an essential element. This means that if the cylinders fails or malfunctions, speed is of the essence when it comes to replacement or repair, potentially the entire operation the cylinder is essential to may have ground to a halt. For this reason, cylinders need to be hardy and robust – which is why they are made out of high-strength steel. When buying from a hydraulic cylinder supplier, a manufacturer will prioritise reliability and durability.
A significant part of the process of manufacturing cylinders is done by hand. Though much of the work is carried out by machines (with powerful drills creating the piston itself), the placement of the piston rod in the cylinder is a delicate process – one that must be done by human hands to avoid damaging the cylinder. The screws on the cylinder head are also added by hand, as are the sealers. Careful and comprehensive testing and measuring by humans is also necessary to make sure each piece will fit into and work with one another perfectly.
Some hydraulic cylinder suppliers will provide custom-built cylinders, which have been designed and created for a very specific application. These cylinders cost more, but will often be a more cost-effective solution in the long run, as they will perfectly fit the requirements they were made for, and last longer as a result. The ability to create cylinders according to precise requirements and specifications is thanks to CNC (computer numerical control) machines, which can be programmed to do the cutting and drilling to exact measurements. This means that even if a manufacturer requires one hundred cylinders, each one will be identical down to the millimetre.
Hydraulic cylinder suppliers can provide all sizes of cylinders, from very small to extremely large to everything in between. And with the wide variety of uses for cylinders in so many industries, there is no shortage of demand.
