Leading Metric Oil Seal Manufacturers

Metric oil seals are non-metallic rings that are used to prevent leakage of liquids in hydraulic systems; they are used primarily in countries that do not use the American system of measurement. Hydraulic systems are machines that use pressurized hydraulic fluids to facilitate the movement of equipment.

Bulldozer shovels, for example, are moved by hydraulic cylinders filled with pressurized hydraulic fluid. That fluid is transmitted throughout transmission lines and cylinders. This movement of the fluid forces pistons and other similar equipment back and forth; the equipment connected to the pistons moves as a result. Oil seals, which are sometimes also known as hydraulic cylinder seals, are necessary to help prevent contamination of hydraulic systems. They are also used to help maintain fluid pressure in those systems.

Hydraulic cylinders and fluid transmission lines must be carefully controlled in order to ensure that the entire system performs as it should. Contaminants and poor seals in a hydraulic system can cause inefficiency in that system and sometimes failure. Total and even partial failure of hydraulic systems, particularly in cases when those systems are applied in load bearing or lifting capacities, poses a very severe hazard to nearby people and objects.

For example, if an earth mover's hydraulic cylinder failed while lifting a large amount of dirt, the rapid and unexpected descent of the equipment could cause serious damage to anything in its falling path. Also, the impact could cause damage to the rest of the equipment, which could derail whatever project in which it was involved.

Properly installed and maintained oil seals help reduce the chances of hydraulic system failure. Metric oil seals and American oil seals are both important parts of all kinds of industrial, commercial and consumer utilities. Carefully pairing them with their applications is important ensuring the sustained effectiveness of the machinery in which they are used.
