The AirTAC Airtac SC40 Standard Cylinder SC40X435S is a genuine double-acting standard air cylinder with a Ø40mm bore and 435mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X435S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), driven by a 16 mm diameter piston rod. Its 435 mm stroke sits well within the 1200 mm maximum standard stroke for the 40 mm bore, making it a standard-order item with no extended lead time.
This model carries the -S suffix, meaning a magnet is built into the piston. That lets you clip CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the tie-rod barrel for reliable end-of-stroke or mid-stroke position sensing without external brackets. The adjustable air cushion at each end (21 mm cushion length) decelerates the load smoothly, and the PT1/4 port threads accept standard pneumatic fittings.

The built-in magnet lets you mount CMSG/DMSG sensors to confirm cylinder position at each end of the 435 mm stroke, ideal for pick-and-place or diverting stations on packaging lines.
628 N of force at 0.5 MPa provides solid workpiece clamping. Sensor feedback confirms the clamp is fully engaged before a machining or welding cycle starts, improving safety and cycle reliability.
The 435 mm stroke suits sliding gates or flow diverters in material handling. The magnet allows remote position verification without physical limit switches, simplifying wiring and maintenance.
For applications needing more force, stepping up to the 50 mm bore (SC50) raises push force to 982 N at 0.5 MPa. If a shorter, lighter cylinder is acceptable, the 32 mm bore (SC32) provides 402 N at the same pressure. At 435 mm stroke, the 16 mm rod is adequately supported for purely axial loads, but any significant side load or off-centre mass will require an external linear guide or a guided-cylinder configuration to protect the rod bearing from bending stress.
When replacing an existing unit, match five points: 40 mm bore, 435 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no accessory) mounting. This is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a drop-in ISO interchange part.
Quick checklist
At the standard operating pressure of 0.5 MPa, this cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the extending force rises to 1130 N.
Yes. The -S suffix indicates a factory-installed magnetic piston. AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors mount directly onto the tie-rod barrel to detect piston position. Without the -S option, the piston is non-magnetic and these sensors will not function.
