Product Introduction
We promote the development of the hydraulic o rings, Square Composite Piston Seals, vee packing seals industry through innovation, continuously improve product quality through user feedback, and reflect corporate value by meeting user needs. We have formed a more complete domestic and international sales channels, and actively explore overseas markets. After years of development, our company has formed a marketing network and service system that radiates globally and moves into the international market.
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.

Features
This Hydraulic Cylinder Rod Glyd Ring has the following features:
1) For both static and dynamic applications, the optimal seal is available.
2) There is no stick-slip effect because of the low coefficient of friction.
3) Extrusion resistance and wear resistance are both excellent.
4) Depending on the O-ring material, a wide temperature range and great chemical resistance are possible.


The company has 5,000 square meters of professional production plants, 2000 square meters of constant temperature and humidity production workshop, dozens (of sets) of advanced production equipment.
