Z8 type sealing ring for cylinder hole

Z8 type pneumatic seal is a kind of lip seal for cylinder piston and valve. The Z8 type standard series corresponds to the bore of the ISO3320 and CETOPRP52P, RP43P, RP53P standards.

I. Scope of Application
Working pressure: ≤ 1.6Mpa
Working temperature: standard material NBR: -20 to 80C
Imported polyurethane TPU: -35 to 80C
Reciprocating speed: ≤ 1 m/s
Working medium: oil-lubricated air, dry air and oil-free air (after initial lubrication with oil)

Second, the main advantages
The special structure of the Z8 lip seal has the following advantages when used in pneumatic equipment: small installation groove and good sealing performance. Due to the optimum sealing lip geometry to maintain the lubricant film, and also due to the use of pneumatic equipment. It is proved to be a very suitable synthetic rubber material, so the operation is very stable. The structure is small, so the static and dynamic friction is very low. Suitable for dry air and oil-free air. The initial lubrication during assembly plays an important role in extending the working life. The lip seal structure ensures the proper function of the seal. Easy to fit into the sealing groove. It is also suitable for cylinders with buffering effect.

3. installation
This type of Z8 pneumatic piston seal can be easily installed in the groove on the piston. To avoid damaging the seals, remove the sharp edges on the live and cylinder barrel. In the case of no lubrication, it is important to obtain a complete lubrication film in the cylinder, which should be done before assembly to ensure the working life of the seal.
