About Hydraulic Support Ring
The hydraulic support ring is made of filled polytetrafluoroethylene PTFE and is used on the piston or piston rod of the hydraulic cylinder or cylinder. Supports the moving parts of the piston or piston rod. It can prevent the piston or piston rod from direct contact and friction with the cylinder during movement, protect the cylinder and the piston or piston rod from damage, and mainly serves as support and guide.

Introduction
The wear resistance of the hydraulic support ring in the seal system is key to increasing the service life of the overall component. The wear of seals is mainly divided into abrasive wear, abrasive wear and lubrication wear. Factors such as friction, pressure, temperature and media will also affect the wear resistance of the sealing system.
Hydraulic support rings enhance the performance of other hydraulic seals by providing additional support and anti-extrusion force. They are usually installed on one or both sides of an O-ring or other primary seal. Hydraulic seals play an integral role in ensuring the efficient operation of hydraulic systems.
Advantages
1. Improve sealing performance
By providing additional support to the main seal, the support ring can help prevent leaks and improve overall sealing performance. This is especially important in high-pressure applications, where even small leaks can cause significant losses in system efficiency.
2. Extend seal life
In addition to improving sealing performance, backup rings can help extend seal life by reducing wear. By providing a barrier between the seal and the piston or rod, the support ring prevents damage from friction and vibration that can otherwise cause premature seal failure.
3. Enhance system stability
Support rings can help improve the stability and reliability of hydraulic systems by reducing the risk of leaks and premature seal failure. This is especially important in applications where downtime is costly or dangerous, such as industrial machinery or heavy equipment.
Overall, hydraulic support rings are an important component of any hydraulic system that requires reliable and efficient performance. Providing additional support and protection to your system’s primary seal helps prevent leaks, extend seal life, and improve overall system stability.
The Difference Between Support Ring and Guide Ring
The hydraulic cylinder is an important part of the hydraulic system and consists of a variety of components. The support ring and the guide ring are two important components. Although they are very similar in appearance, they have obvious differences in function and structure.
1. Support ring
The cylinder support ring is a component used to support the piston. It is usually located between the piston and the end cover. It has high strength and hardness, can withstand large lateral forces, and can keep the geometry of the cylinder stable.
2. Guide ring
The guide ring is a component used to position the piston, usually between the piston and the cylinder barrel. Guide rings are usually made of polymer materials and have good wear resistance and corrosion resistance. Its main function is to keep the direction of movement of the piston in the cylinder barrel stable and to prevent the piston from deviating during movement.
Through the above introduction, we can see that there are differences in the functions and structures of the support ring and the guide ring in the hydraulic cylinder. The hydraulic support ring is mainly used to support the geometry of the cylinder and withstand lateral forces, while the guide ring is mainly used to position the piston and keep its direction of motion stable. Although the two are similar in appearance, they play different roles in the composition of the hydraulic cylinder.
Conclusion
In hydraulic systems, support rings and guide rings are common components with a wide range of uses. From the above, we understand that there are obvious differences in their structures and functions, which can effectively avoid confusing use, improve the service life and work efficiency of the hydraulic system, and also avoid failures and damage caused by improper use of these components.
