Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. They also compensate for large temperature fluctuations. Back up ring including BRT, N4W. Hydraulic cylinder seals prevent the leakage of working medium (internal and external leakage) and prevent foreign objects (such as air, dust and water) from entering the hydraulic components and hydraulic system.
BACK UP RING
Applications
Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. They also compensate for large temperature fluctuations.
Hydraulic cylinder seals prevent the leakage of working medium (internal and external leakage) and prevent foreign objects (such as air, dust and water) from entering the hydraulic components and hydraulic system.
YUDI mian seal is PTFE+Ring, can resist pressure 200-300 bar, but PTFE material can not resist 300-500 Bar. To prevent pushing problem and increase pressure resistance,install the back up ring on both sides of the PTFE
Back up ring including BRT, N4W
Material: Nylon;
Color: As per customer request if you have large quantities;
First, the back up ring of the hydraulic cylinder seal:
The support ring of the hydraulic cylinder seal is installed on the inside of the end cover of the hydraulic cylinder. YD seals tell you that the main role is to support the piston rod; preventing the piston rod from vertical pressure to bring uneven sealing pressure caused by the rod seal and the poor sealing effect. Short life and other effects.
Second, the guide ring of the hydraulic cylinder seal ring
The back up ring of the hydraulic cylinder seal is installed on the piston, and its main function is to guide the piston to perform linear motion, to prevent the piston from deviating due to uneven force, causing internal leakage and reducing the life of the seal.
3. The service life of the back up ring and the support ring directly affects the use effect and life of the piston seal and the piston rod seal, so the requirements for the back up ring are also high, such as low friction coefficient, high hardness, long service life, etc. .
4. There are many forms of guide belts and support rings, and they are also used in combination with the main seal.
Back up ring are installed in a groove with an elastomer O-Ring. Due to their tight fit in the housing, Back-up Rings prevent extrusion of the pressurized elastomer sealing element into the clearance or extrusion gap.
