Product feature
1.Standard cylinder manufactured by our enterprise.
2.The seal of piston adopts heterogeneous two way seal structure. It's dimension is tight and it has the function of oil reservation.
3.It is no tie rod cylinder. The cylinder barrel is "Mickey Mouse" shape ,and have good corrosion
4.Compared with ISO15552 standard cylinder, SU series cylinder with the same bore size is shorter
5.The buffer adjustment of cylinder is smooth and steady
6.Mounting accessories are the same as SC series
7.The seal material with high temperature resistance is adopted to guarantee the normal operation of cylinder at 150C

Product Advantages
Installation and application
1. Whenload changesin the work, the cylinder with abundant output capacity shall be selected.
2. Relative cylinder with high temperature resistance or corrosion resistance shall be chosen under the condition of high temperature or corrosion.
3. Necessary protection measure shall be taken in the environment with higher humidity, much dust or water drops, oil dust and welding dregs.
4. Dirty substances in the pipe must be eliminated before cylinder is connected with pipeline to prevent the entrance of particles into the cylinder.
5.The medium used by cylinder shall be filtered to 40um or below.
6. Anti-freezing measure shall be adopted underlow temperature environment to prevent moisture freezing.
7.The cylinder shall be carried out test run without load before application. Prior to run, buffer shall be turned to the minimum and gradually released to avoid the damage on cylinder caused by excessive impact.
8.The cylinder shall avoid the influence of side load in operation to maintain the normal work of cylinder and extend the service life.
9. If the cylinder is dismantled and stored for a long time, please conduct anti-rust treatment to the surface. Anti-dust caps shall be added in air inlet and outlet ports.
FAQ
