Wear Rings Manufacturers, Suppliers & Exporters In India. Wear rings are components used in hydraulic and pneumatic systems to reduce friction and prevent metal-to-metal contact between moving parts. These rings act as guides and support elements within cylinders, ensuring smooth operation and minimizing wear. Wear rings are used in hydraulic and pneumatic cylinders, pumps, and other reciprocating equipment. They are common in industries such as manufacturing, construction, aerospace, and automotive. Wear rings are installed in grooves on either the piston or the cylinder bore, depending on the design of the system. Proper installation is crucial to ensure that the wear rings function as intended.
