The AirTAC Airtac SC40 Standard Cylinder SC40X90S is a genuine double-acting standard air cylinder with a Ø40mm bore and 90mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X90S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 90 mm stroke, delivering 628 N of push force at 0.5 MPa (1130 N at the 0.9 MPa maximum operating pressure). Its 16 mm diameter piston rod and PT1/4 ports suit compact automation tasks where moderate force and a short stroke are required.
This model includes the -S suffix, indicating a built-in magnet along the barrel. The magnet allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors to detect piston position without external brackets, simplifying end-of-stroke or mid-stroke sensing on packaging and assembly equipment.

The built-in magnet and CMSG/DMSG sensor compatibility make the SC40X90S ideal for pick-and-place units and small assembly fixtures that require precise end-of-stroke confirmation to the PLC.
With 628 N of push force at standard shop air, this 90 mm stroke cylinder reliably actuates gates and diverters on light to medium-duty packaging conveyors, sorting cartons or pouches.
The 16 mm rod and 1130 N maximum force suit clamping, holding, or light press-fit operations on jigs and fixtures, where the adjustable air cushion protects tooling from impact damage.
Choose the SC40 bore when your application needs between 628 N and 1130 N of pneumatic force. If you require higher force, step up to the SC50 bore which provides 982 N at 0.5 MPa; for a lighter, more compact solution, the SC32 bore offers 402 N at the same pressure. Always confirm your load, speed, and available air pressure before finalizing the bore size.
For a drop-in replacement, match these five points: 40 mm bore, 90 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting configuration. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. These values assume clean, filtered air at 40 µm and a standard double-acting circuit.
Yes. The -S suffix means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional mounting hardware.
