The AirTAC Airtac SC40 Standard Cylinder SC40X260S is a genuine double-acting standard air cylinder with a Ø40mm bore and 260mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X260S is a double-acting tie-rod cylinder with a 40 mm bore and 260 mm stroke, pre-fitted with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. It generates a push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator for clamping, pressing, and sorting tasks.
This model uses a 16 mm diameter piston rod with an M12x1.25 male thread and a standard PT1/4 pneumatic port. The adjustable air cushion at each end provides a 21 mm deceleration zone, reducing end-of-stroke impact. The total body length A is 142 mm, giving an approximate extended length of 402 mm. The standard temperature range with TPU seals is -20 to +70 °C.

The 260 mm stroke and 628 N push force at 0.5 MPa efficiently actuates a gate or diverter arm on a packaging conveyor, while the built-in magnet allows end-of-stroke confirmation via a CMSG sensor.
Delivers up to 1130 N at 0.9 MPa for pressing bushings or bearings into light alloy housings. The adjustable cushion softens the impact when the tooling bottoms out, protecting the part.
Raises and lowers a heavy-duty stop blade at a palletizing station. The 16 mm rod and tie-rod construction provide the rigidity needed for frequent, repetitive cycling in a dusty environment.
Select the SC40 when your application needs between roughly 500 and 1100 N of push force at standard shop air. If your load consistently exceeds 900 N, consider stepping up to the SC50 bore, which provides 982 N at 0.5 MPa. For strokes of 260 mm, the 16 mm rod is robust for purely axial loads; however, if the cylinder experiences any side loading, an external linear guide or a guided cylinder should be used to prevent rod bending and premature seal wear.
To guarantee a drop-in replacement, match five key points: a 40 mm bore, 260 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC40 of the same stroke.
Quick checklist
At 0.5 MPa (approx. 73 psi), 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 at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. A direct replacement requires another AirTAC SC40 cylinder with a 260 mm stroke, PT1/4 port, and a built-in magnet.
