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.

Combining compact cylinder size and rotational capability, the MK2 cylinder is designed for heavy duty clamping applications, with an available integrated arm that swings out of the way when the cylinder is extended. 90deg. clockwise or counter clockwise rotation is available, and clamping arms with adjustment screw are standard options. MK2 is available in 6 bore sizes from 20mm to 63mm and stokes from 10 mm to 50 mm.

This product is being discontinued and will be replaced by CK1-Z1 series.
At SMC we are tightening our hold on the clamp cylinder market with the launch of our CK1-Z series. This updated series features improved speed adjustments and optimised tube lengths, reinforcing our investment in research and development to meet our customers’ commercial needs. Either end features a built-in, easily adjusted speed controller delivering both labour and space savings. Shorter in length, other user friendly features include a simple to adjust, flexible air cushion, as well as magnetic field resistant auto-switches mountable from three directions and an optional auto switch mounting rod. Piping flexibility is achieved through the ports located on three surfaces. The CK1-Z Series is ideal for clamping operations in locations that have standard or strong magnetic fields, and in the automotive manufacturing sector.

With the addition of two new space-saving options to our popular Series C(L)KG and C(L)KP clamp cylinder we now have some great solutions for robot assembly and welding applications. These latest cylinders, which can be selected with or without lock, are almost 20% shorter and 50% lighter than our existing products. Available in 25, 32 and 40mm small bore sizes, these ultra-compact, slim style cylinders can also be used in conjunction with our small, magnetic field resistant, dual colour auto-switch range - Series D-P3DW.

SMC's CKZ2N power clamp cylinder conforms to the new NAAMS standard. The rounded cover design and release button with minimal protrusion, reduce weld spatter accumulation. The arm opening angle can be easily changed by replacing the stopper bolt. The CKZ2N is available in sizes equivalent to 50, 63 and 80mm bore with arm opening angles ranging from 30° to 135°.
