The AirTAC Airtac SC40 Standard Cylinder SC40X304S is a genuine double-acting standard air cylinder with a Ø40mm bore and 304mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X304S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 304 mm stroke is a non-standard length made to order, extending the 16 mm diameter piston rod to a total extended body length of approximately 446 mm.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for contactless position sensing. The adjustable pneumatic cushion at both ends, with a 21 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact.

The 628 N push force at 0.5 MPa easily actuates a gate or diverter arm on a conveyor, sorting cartons by weight or barcode with a reliable 304 mm stroke reach.
With the built-in magnet and CMSG sensors, the cylinder confirms clamp closure in a fixture, holding a workpiece with 1130 N of force at 0.9 MPa during gluing or fastening.
Provides a 304 mm vertical push stroke to raise a small platform or transfer mechanism, using the adjustable air cushion to softly stop the 16 mm rod and payload at both ends.
Choose the SC40 bore when your application needs around 628 N of push force at standard plant air. If you require more force, step up to the SC50, which provides 982 N at 0.5 MPa. For a lighter, more compact solution, the SC32 offers 402 N. At a 304 mm stroke, the unsupported rod is extended significantly; ensure side loads are minimal or use an external linear guide to prevent rod bearing damage and bending.
For a direct replacement, match five key points: 40 mm bore, 304 mm stroke, PT port thread, the built-in magnet for sensors, and the basic (no bracket) mounting configuration. This cylinder is a genuine AirTAC SC tie-rod unit, which is shorter than an ISO 15552 profile and not dimensionally interchangeable with it.
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 an ISO 15552 cylinder. For a correct fit, you must match the SC40 bore, 304 mm stroke, PT ports, and the built-in magnet configuration.
