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.

• Large bore tie rod cylinder

The MY2 high precision guide cylinder is available in bore sizes 16mm, 25mm and 40mm. This series has been designed with a high precision single or double axis guide to create a compact, low profile cylinder. Maintenance has been simplified by allowing the cylinder to be detached without disturbing the guide unit and work piece.

Following customer requests for range of easy to maintain rotary clamp cylinders with a good selection of stroke variations and dual mounting options, our R&D engineers have simply taken the best features of two existing SMC products – Series MK and MK2 - and put them together in our newly amalgamated and improved Series MK. Available in bore sizes from 12 to 63mm and in clamp stroke lengths up to 50mm depending on the selected model, the new MK Series helps answer our customer's needs with the option of both body and through hole mounting selections and easy maintenance possibilities with fully replaceable seals and guide pins. Designed for use with our compact D-M9 auto switch, which can be mounted on all four sides (only 2 sides in the case of 20 and 25mm) these new rotary clamp cylinders when required can also be used in conjunction with our magnetic field resistant auto switch Series D-P3DW.

This product is being discontinued and will be replaced by CP96-C (ø32-ø100) series.
With the expansion of our Series C(P)96 ISO range, we can now offer our customers even greater flexibility and cylinder performance. Now available in a non rotating rod type (CP96K(W)/C96K(W)), these cylinders offer great precision and deliver non-rotating accuracy of ±0.5º or ±0.3º in Ø32 to Ø63 or Ø80 and Ø100 bore size respectively. Also, we have introduced a smooth cylinder type, with reduced piston sliding resistance (C96Y) which is particularly suitable for transfer applications requiring smooth movements at low pressure. For applications in explosive atmospheres, the C(P)96 range is now available in an ATEX compliant version (55-C(P)96 which meets ATEX category zone 2, or category zone 3 when fitted with an auto-switch). With a growing range of "made to order" options available as standard and a choice of rod boot materials, there has never been a better time to check out our Series C(P)96 cylinder range.

Stock control of the compact auto switches is easy, since a wide variety of auto switches are available.

When car industry experts work alongside research and development engineers from SMC Pneumatics, the world leaders in automation control, theres only one possible outcome the perfect solution! Just one example of this on-going collaboration is SMC´s latest air operated pin clamp cylinder Series CKQ providing simultaneous positioning and clamping.Designed primarily for use in welding and sheet metal applications, this range of spatter resistant double acting cylinders are currently available in four body type options including lock or without lock models. With further choices of either round or diamond type guide pins, to suit hole diameters from 13mm to 25mm, their unique stainless steel construction combined with a outer coating of titanium nitrate (TiN) ensures maximum operational lifetime and increased weld spatter resistance.Other features include the possibility of altering the height of the clamp position by up to 2mm by simply removing the shims, making last minute adjustments a straight forward exercise. Additionally, ease of maintenance has also been recognised by the inclusion of four separate cleaning covers allowing for any weld spatter entering the cylinder to be easily removed without the need of complete cylinder dis-assembly. Designed to operate at piston speeds of 50 to 300 mm/sec, at a maximum operating pressure of 0,7 MPa and within ambient fluid temperature ranges of between minus10º to plus 60ºC, these pin clamp cylinders really are the perfect solution.
