1. Performance and use
Adapts to two-way rod seals. Low friction and simple grooves allow for larger piston rod clearances. Servo cylinders that require quick response are recommended to be preferred.
The adaptability of the working medium and the working temperature range can be changed by changing the material of the O-ring, so the adaptability of the medium and the working temperature range are relatively wide.
It can be used in special working conditions such as extremely high speed, extremely low speed, and micro stroke.
The installation groove is smaller. The seal is easy to install and generally requires no special tools.
Comply with GB/T 15242.1-94 and GB/T 15242.3-94 standards.
Products with different cross-sections can be selected according to the actual working pressure. In principle, the greater the working pressure, the larger the cross-section should be selected.
2. Materials
Sealing ring: Filled with polytetrafluoroethylene (PTFE). According to different working conditions and sealing requirements, different filling materials and filling processes can be selected, please inquire for details.
O-ring: nitrile rubber NBR, fluororubber FKM. The material of the O-ring is determined according to the temperature and working medium of the working condition, if you are not sure, please contact us. If you need to match fluorine rubber (FKM) O-ring, you need to explain before ordering.
3. Precautions:
Ⅰ. If other parameters of the matched O-ring are qualified, the diameter of the ring is 1-2% larger than the value listed in the sample, which will not affect the use.
Ⅱ. When installing, you can bend the sealing ring into a heart shape and put it into the groove, but there must be no creases, as shown in the following two cases, A is allowed, and B is prohibited.
Ⅲ, it is recommended that the surface hardness of the piston rod be greater than HRC40.
Ⅳ. The static leakage is larger than that of the Steering seal, but the service life is longer than that of the Steering seal.
