One of the challenges faced by machine builders is the repeated request for smaller and more compact machines. In many cases this challenge is not too difficult to achieve but often major size reductions are restricted by the performance of the components used in its construction.As the world leaders in pneumatics, SMC are very much aware of these issues and their new Series CQU compact plate type cylinder meets this challenge with both power and space saving performance.Designed for use in general automation application, the CQU range offers the best performance features of SMC´s popular Series MU plate cylinder and Series CQ2 compact cylinders in one exceptionally small plate cylinder body. Thanks to the development of a unique patented elliptical retaining ring, which eliminates the need for cylinder end caps, Series CQU is up to 15% shorter than the MU, 40% narrower than the CQ2 and offers a body mass reduction of up to 36% depending on the selected model. A further benefit of this innovative construction ensures that the CQU range is also dramatically lighter than any plate cylinder currently in the market.Ideal for tight pitch mounting applications or where you need to mount a cylinder with a low centre of gravity, Series CQU can also be used with an external guide. Designed for use with a small auto switch – which can be fitted in 4 directions – Series CQU can also be mounted using vertical, horizontal, foot and double clevis options.
