1.Application and properties

Suitable for double-acting rod seal. It has low friction coefficient and a simple groove structure, and can be used for larger rod clearances. It is recommended to prioritize for servo cylinders requiring rapid response. It can be used for special conditions such as extremely high speed, extremely low speed, micro-stroke etc.

The working medium adaptability and working temperature range can be changed by replacing the material of the O-ring

The installation groove is small, which is beneficial to design the size of cylinder. The seal is easy to install and generally does not require special tools.

Compliant with GB/T 15242.1-94 and GB/T 15242.3-94 standards.

Products of different sections can be selected according to the size of the actual working pressure value, in principle, the greater the working pressure, the larger the cross-section should be selected.
