The AirTAC Airtac SC40 Standard Cylinder SC40X66 is a genuine double-acting standard air cylinder with a Ø40mm bore and 66mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X66 is a double-acting tie-rod cylinder with a 40 mm bore and a custom 66 mm stroke, ideal for compact linear applications where a standard 50 or 75 mm stroke is too long. It generates a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod.
With a body length A of 142 mm, this cylinder's total extended length is approximately 208 mm. The adjustable pneumatic cushion at each end (21 mm length) decelerates the piston smoothly, reducing end-of-stroke impact. This model features PT1/4 ports and an M12x1.25 rod thread, with TPU seals for standard -20 to +70 °C operation.

The 66 mm stroke and 628 N force at 0.5 MPa are well-suited for actuating compact part stops or diverting gates on light-duty conveyor lines.
Provides controlled clamping force for small assembly or welding jigs, where the non-standard 66 mm stroke offers a precise fit for the fixture's geometry.
Suitable for automating small ball or butterfly valves in processing lines, where the 16 mm rod and adjustable cushion ensure reliable, low-impact operation.
Select the SC40X66 when you need a non-standard intermediate stroke in a 40 mm bore. If your force requirement is lower, the SC32 series provides 402 N at 0.5 MPa; for higher force, step up to the SC50, which delivers 982 N at the same pressure. Always match the bore, stroke, port thread (PT), and mounting accessory when replacing an existing cylinder.
For this 66 mm stroke, side loading is not a primary concern, but ensure the load is guided and aligned with the rod axis. The tie-rod construction allows for easy maintenance, but it is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the push force is 628 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No, 66 mm is a non-standard stroke. Standard strokes for the 40 mm bore include 50 mm and 75 mm. A 66 mm stroke is a made-to-order configuration, so confirm lead time with your supplier.
