Electric cylinders

Benefit in many cases

Benefit in many cases

When applications such as pick-and-place or lifting and clamping processes require high force, a suitable cylinder is needed. At the same time, force is not everything: speed, precision and flexibility during assembly are also extremely important aspects that determine the overall appearance of a cylinder solution. The specialist for pneumatic and electric automation SMC has therefore revised its CXS series once again and, with the CXS2 series, offers a double-piston cylinder that impresses in several respects: from the increase in output force and standard strokes to a more than doubled piston speed and 7 times the permissible kinetic energy.

Clamping processes or workpiece transports require high forces. At the same time, precision, productivity and flexible assembly as well as lightweight machine design are required. With the CXS series, SMC already has impressive double-piston cylinders in its portfolio. In addition, the automation specialist now offers a comprehensively optimized double-piston cylinder with the CXS2 series. Among other things, users benefit from a piston speed of 800 mm/s, higher standard strokes of up to 200 mm, a permissible kinetic energy of 0.016 J at a piston diameter of 6 mm, a weight reduction of up to seven percent and extensive mounting and connection options.

New top performer among the cylinders

The double piston design, in which the bearing design can be selected between ball bearing and plain bearing, ensures double the thrust force. This has been increased by around 14 percent by enlarging the piston diameter from 15 to 16 mm to an initial force of 1126 N. The sizes 6, 10, 20, 25 and 32 mm are also available for the piston Æ. Thanks to the piston speed of up to 800 mm/s (piston Ø 6 and 10 mm), which has been increased by a factor of 2.5 compared to the previous series, users benefit from greater productivity.

SMC has also made significant improvements to the existing standard strokes: Stroke ranges of 1 to 100 mm (piston Ø 6 mm), 1 to 150 mm (piston Ø 10 mm) and 1 to 200 mm (piston Ø 16 to 32 mm) are available. Compared to the CXS series, these have been doubled in some cases. This means that users can achieve the required stroke with a smaller piston diameter without having to switch to the next larger version. Compared to the standard stroke, the stroke can be easily adjusted from 0 to -5 mm at the front using a hexagon nut.
More robust, lighter and precise

The CXS2 series also comes up trumps in terms of permissible kinetic energy: Whereas a maximum of 0.0023 J was permissible for the predecessor with a piston Ø of 6 mm, now up to 0.016 J is possible, which is around 7 times higher. With a piston Æ of 32 mm, the value is even 0.32 J. At the same time, users benefit from lighter machines overall thanks to the seven percent weight reduction from 0.15 to 0.14 kg (piston Æ and stroke ten mm each).

Thanks to the double-piston design, the CXS2 series, which is suitable for ambient and media temperatures of -10 to 60 C° (no freezing), has a torsional accuracy of ± 0.1°. In addition to high force, it also impresses in terms of precision. The optionally mountable compact signal transmitters of the D-M9 and D-A9 series from SMC and the elastic damping also contribute to a high level of process control.

A gain in flexibility

Users have four options for mounting the housing: Fixation from below (fixed housing), fixation from above (through-hole fixation) and lateral fixation, either with fixed housing from side A or from side B. You can choose between M-thread (piston Ø 6 to 20 mm) or Rc1/8, NPT1/8 and G1/8 (piston Ø 25 and 30 mm). A workpiece can be mounted either from the front, from below or from above. The line connection can be made from two sides - an axial connection is also possible for piston Ø 6 mm.

Thanks to the same mounting dimensions, users of the previous CXS series can easily replace them with the new CXS2 series. This allows them to quickly and easily update their machines, benefiting from high force and precision while reducing weight in the smallest of spaces.
