DMS SEALS TECHNOLOGY CO.,LIMITED
DMS Seals-Mechanical Seals and Oil Ring Seals Manufacturer
The Professional Sealing Solution Supplier(O Ring Suppliers & Oil Seal Manufacturers).
1. Performance and use
It is suitable for two-way sealing of reciprocating pistons, especially high-pressure heavy-duty oil cylinders that require low friction, no crawling, and quick response, such as metallurgy and construction machinery.
Small coefficient of friction, wear resistance, long life.
The working medium adaptability and working temperature range can be changed by changing the material of the square ring.
It can be used in special working conditions such as extremely high speed and extremely low speed.
Adapt to the one-piece piston, the installation groove is small, which is beneficial to the design of the cylinder size.
Comply with GB/T 15242.1-94 and GB/T 15242.3-94 standards.
The working pressure is high, the extrusion resistance is good, and the installation gap is larger than that of ordinary seals.
Sealing ring: Filled with polytetrafluoroethylene (PTFE). According to different working conditions and sealing requirements, different filling materials and filling processes can be selected, please contact us for details.
Square ring: nitrile rubber NBR, fluororubber FKM. The material of the square ring is determined according to the temperature and working medium of the working condition, if you are not sure, please contact us. If it needs to be equipped with fluorine rubber (FKM) square ring, please explain before ordering.
Ⅰ. This seal is designed for heavy-duty oil cylinders, and it is recommended to be used with caution for light-duty oil cylinders (oil pressure<10MPa).
Ⅱ. For the matching square ring, if other parameters are qualified, the diameter of the ring is 1-2% different from the value listed in the sample, which will not affect the use.
Ⅲ. Before installation, use tooling or hot oil to expand the slip ring, and return it to its original shape after installation.
