Product Features

CQ2B cylinder tube, as an innovative design of aluminum cylinder barrel, achieves spatial optimization through thin-walled structure. After rolling the large-diameter inner diameter of CQ2B cylinder tube, the aluminum cylinder barrel treated with hard oxidation not only significantly improves its surface hardness, but also endows it with excellent wear and corrosion resistance. The piston sealing system designed specifically for CQ2B cylinder tube adopts an irregular bidirectional structure, and its innovative oil storage function ensures the long-term lubrication stability of CQ2B pneumatic cylinder.
The specially designed magnetic slot structure enables the CQ2B pneumatic cylinder to stably support four side mounted magnetic switches. This special structure based on aluminum cylinder barrel makes the CQ2B cylinder tube an ideal choice for fast assembly lines. As a typical thin-walled cylinder, the CQ2B pneumatic cylinder series offers a variety of configurations from standard to magnetic versions, M external tooth versions, etc., to meet the customized needs of aluminum cylinder barrel in different industrial scenarios.
CQ2B cylinder tube stands out in automation scenarios such as electronic product assembly and light industry textiles due to its fast response characteristics. As the core component of the high-precision CQ2B pneumatic cylinder, its aluminum cylinder barrel needs to be used in conjunction with clean and dry compressed air to strictly avoid the mixing of synthetic oil, salt, and corrosive gases, ensuring the precise fit of the moving parts inside the CQ2B cylinder tube.
It is particularly important to note that the CQ2B pneumatic cylinder must be thoroughly purged of the connecting pipes before installation. This pre-treatment can effectively prevent impurities from entering the interior of the aluminum cylinder barrel. For the long-term operation of the CQ2B pneumatic cylinder tube system, it is recommended to install a precision filter at the gas source inlet to maintain the long-term stable operation of the CQ2B pneumatic cylinder.
