The requirements for Pneumatic cylinder are constantly increasing in terms of design, hub, maintenance and energy efficiency. SMC offers ISO cylinders from the CP96 series in accordance with DIN ISO 21287, specifically double-acting in four new versions. They include an ISO standard and compact version, an ISO-based version with energy return and an energy-efficient compact cylinder. This special pneumatic cylinder with energy recovery and the compact cylinder offer a reduction in compressed air consumption of up to 48% - one world first.
For pneumatic applications in the automotive industry, machine tool construction, material handling or automation, ISO compressed air cylinders are used, which with their comprehensive properties ensure high process reliability. In addition to the basic functions, a large number of different strokes, simple assembly even in tight spaces, uncomplicated maintenance and a energy efficient consumption required. The specialist for pneumatic and electrical automation SMC offers pneumatic cylinders of the CP96 series double-acting in four different versions.
Pneumatic cylinder: extremely short and light
The new construction of the compressed air cylinder is immediately noticeable: the tubing for the Energy return takes place via the three connections retraction, energy return and extension. The connections of the pneumatic cylinders are arranged on the cover side and are therefore immediately recognizable. While the standard cylinder with a piston diameter of 63 mm is a whole 14 mm shorter than the previous model, the compact cylinder has been shortened by a further 29 mm and thus by 12%. This also has a positive effect on the weight if a pneumatic piston with a diameter of 22 g is 13% lighter.

The pneumatic cylinders CP96 in a small implementation can be used extremely flexibly thanks to the radical reduction in length and weight. Process engineers can easily use the pneumatic cylinder in areas where conventional ISO cylinders are too long. They can also create very compact and lightweight machine designs.
In the CP96 series, the number of grooves and unevenness on the housing of the cylinder barrel, head and cover has been reduced in all four variants. This gives the pneumatic cylinders a smooth surface, on which dust and other foreign matter can settle less and, if they do, can be removed more easily. This makes maintenance easier and improves process reliability on the air cylinder.
Large selection of variants
With the standard and Compact cylinder Double-acting and in accordance with ISO 15552, for piston rods with a diameter of 32, 40, 50 and 63 mm, the stroke can be 25, 50, 80, 100, 125, 160, 200, 250, 320, 400, 500 and 600 mm. (the latter only for pistons Æ 50 and 63 mm). When the piston rod extends, pneumatic and elastic damping takes place. The two particularly energy-efficient versions (also available as standard and compact versions) enable strokes of 25, 50, 80, 100, 125, 160 and 200 mm with the piston Æ mentioned above - in this case the latter only with a piston Æ of 63 mm. The damping takes place pneumatically and elastically when extending, and elastic when retracting.

The energy-efficient pneumatic cylinders of the CP96 series make the energy return function a real highlight. The technology used makes it possible to use the air from the working stroke for the return stroke of the cylinder. This reduces the consumption of compressed air by up to 48% overall. In addition to cost savings, this is also good for the environment. The lower energy consumption leads to less CO2 Emissions. The minimum and maximum operating pressure is 0,4 or 0,7 MPa, for the variants without energy return it is 0,05 or 1,0 MPa.
There are many mounting options
Project engineers stand diverse options for mounting of the new CP96 pneumatic swivel cylinder. The two variants without energy return can be attached as a basic version, with a flange at the rear and with a swivel mount and clevis mount. In the standard version, there are also fastenings with a foot and with a flange at the front. The pneumatic cylinders with energy recovery can be mounted both as a basic version and with a flange at the rear. The standard version is also available with a foot or with a flange at the front.
Reading tip: Rollon | The engineering partner
For the latter pneumatic cylinder, the installation direction must be horizontally or vertically because the air cylinders only work with the extension stroke, while the retraction stroke only takes place with low pressure or low force. In addition, the compact cylinder with energy return only partially complies with ISO standard 15552. The standard version of the counterpart conforms to the mounting dimensions of the specified standard.
