Description
This Hydraulic Cylinder Rod Glyd Ring is a double-acting composite rod seal composed of a filled PTFE friction ring and pre-tightened rubber O-ring. They can be assembled in grooves according to standard ISO 7425/2. And this Hydraulic Cylinder Rod Glyd Ring can be used for reciprocating hydraulic systems.
It has an excellent performance in high, medium, low pressure, and high load, high-frequency conditions. What's more, it is a very effective and reliable low friction seal. It is particularly suitable as a rod seal in high-pressure and low-pressure systems.
Bulldozers, excavators, forging machines, brick presses, rolling mills, servo valves, and other machine tools all benefit from our Hydraulic Cylinder Rod Glyd Ring, which is especially ideal for long strokes and bigger rod diameters in fluids and high pressures. The various sliding ring colors, such as black, green, coffee, yellow, and others, may meet most of your color requirements.
