Compact Pneumatic Cylinders

Following a review of our popular CQ2 compact cylinder Series our R&D engineers have totally redesigned the complete cylinder range to bring you even more performance benefits and increased cylinder options. The major difference between the new CQ2 range and the old model is the totally redesigned body, which offers improved auto-switch mounting possibilities plus an overall reduction of cylinder weight of between 5 -13% depending on the model. Now, all CQ2 cylinders from Ø 32 to 200mm are designed with slide in grooves which can accommodate auto-switches on all four cylinder sides without the need for auto-switch brackets. And, for smaller bore sizes between Ø 12 and 25mm, slide in grooves have also been integrated in the new body design to accommodate bracket free auto-switches on two surfaces. Designed for use with our simple to set, dual colour, solid state auto-switches, the integrated auto-switch channel ensures total protection against potential accidental damage and improved health and safety benefits during both installation and maintenance procedures.

The CQS compact cylinder is available for those small bore cylinder applications where saving space is a concern. While sharing many of the outstanding features of the CQ2 series, the CQS offers standard long strokes (up to 300mm) in four bore sizes from 12 to 25mm. Long stroke versions incorporate a wear band and thicker piston to handle the increased bearing needs of the longer strokes. Both switch capable and non-switch capable body styles are the same, and switches can be mounted on three (12-16 bore) and four (20-25 bore) sides. An increased side load version (CQS*S) is available for more demanding applications.

The CQM is a compact cylinder integrated with a guide rod and plate. The series is available in 12, 16, 20, 25, 32, 40, 50, 63, 80 and 100mm bore sizes with the same mounting dimensions as the CQ2. The guide rod and plate allow work to be directly mounted. The CQM series offers 4 times the lateral load resistance of the CQ2K and non-rotating accuracy of ±0.2°.

The RQ series' new air cushion construction allows this series to retain the merits of a compact cylinder. The unique air cushion construction eliminates the cushion ring used in conventional type air cushions, which reduces the overall length of the cylinder. The RQ series meets the demands for reduced shock, noise reduction and improved repeatability at the stroke end.

Machine builders who traditionally use a cylinder and solenoid valve for pushing and clamping applications now have a space and time saving solution with the launch of SMC´s new Series CVQ cylinder and valve range.Developed initially to provide a unique all-in-one compact cylinder/valve system, engineers from world leaders SMC have simply taken their most popular compact CQ2 cylinder and V100 solenoid valve and literally built them together in one single unit. By adopting this innovative approach, the new CVQ cylinder range offers some major space savings as there is no need to allocate space for either the valve or the necessary piping. And by eliminating the piping, further performance benefits are also achieved such as reduced pressure drop and air consumption - by up to 37% per cycle - plus improved response speed when compared to previous separate cylinder and valve configurations. As a single one piece unit, the new CVQ only requires only three piping connections instead of seven connections as previously required thereby ensuring reduced labour time for both installation and maintenance.Currently the CVQ Series combines a double acting compact cylinder in either 32mm, 40mm, 50mm or 63mm bore sizes for application requiring cylinder speed of between 50 – 500 mm/s and a 2 position solenoid valve, which is IP 40 dust proof and is available in low power consumption 24 or 12 V options.

The MU plate cylinder, with its elliptical design, provides a low profile while maintaining force output. The MU cylinder can eliminate the need for higher operating pressures that may be required for typical flat cylinders. The oval piston shape also provides an intrinsic non-rotating function without having to use a rod with flats, offering increased bearing and seal life.

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.

Compact cylinder series CLQ, although equipped with locking function, is designed to minimize the overall length. Overall length of the model is achieved to be the same as that of the CQ2 compact cylinder. CLQ is available in 5 bore sizes ranging from 40 to 100mm and is auto switch capable.

Following automobile industry requests for a lightweight small cylinder with a simple lock function. SMC Pneumatics, the world leading automation control experts, are pleased to announce the launch of their latest range of compact cylinders with both lock and air cushion – series RLQ. Developed to provide the safety of drop prevention, at any point of the stroke, should the air supply be cut off, series RLQ benefits from additional features such as its own built in air cushion, standardized bypass piping and home position holding function. Also with the air cushion and lock unit contained inside the cylinder, the RLQ series offers similar space saving dimensions to SMC’s existing compact CQ2 range. The new series RLQ is the perfect solution for applications which require larger kinetic energy, high stroke repeatability and decreased sound levels.Series RLQ, is currently available in bore sizes of 32, 40, 50 and 63mm, with standard stroke options of between 20 – 100mm, series
