The AirTAC Airtac SC40 Standard Cylinder SC40X335 is a genuine double-acting standard air cylinder with a Ø40mm bore and 335mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X335 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. With a 40 mm bore and 335 mm stroke, it features a 16 mm diameter piston rod and a compact body length of 142 mm, making it suitable for medium-force linear applications where space is a consideration.
This model includes a 21 mm adjustable air cushion at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The standard PT1/4 port and M12x1.25 rod thread ensure straightforward pneumatic connections. As a genuine AirTAC component, it is built for reliable industrial automation with a standard operating temperature range of -20 to +70 °C using TPU seals.

The 628 N push force at 0.5 MPa is ideal for diverting or pushing medium-weight packages on conveyor lines, with the 335 mm stroke providing ample reach across standard belt widths.
Provides consistent clamping force for machining or welding jigs. The adjustable cushion protects the fixture and workpiece by softening the clamping impact at the end of the 335 mm stroke.
Suitable for light-duty pressing or forming operations where a controlled linear motion of 335 mm is needed. The double-acting function allows for powered retraction, speeding up cycle times.
Select the SC40 bore when your application requires around 628 N of force at 0.5 MPa. If you need more force, consider stepping up to the SC50, which provides 982 N at the same pressure. For a lighter, more compact solution, the SC32 delivers 402 N. Always match replacement cylinders across five key points: bore (40 mm), stroke (335 mm), port thread (PT1/4), mounting accessory, and magnet option.
At a 335 mm stroke, the 16 mm rod is well-supported for axial loads, but any significant side loading requires an external guide or a guided cylinder to prevent rod bending and premature bearing wear. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than a standard ISO 15552 cylinder. It is not dimensionally interchangeable. It should only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port, and mounting specifications.
