The AirTAC Airtac SC40 Standard Cylinder SC40X100S is a genuine double-acting standard air cylinder with a Ø40mm bore and 100mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X100S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 100 mm stroke is a standard length for the 40 mm bore, making it readily available for general automation tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The 16 mm diameter piston rod and PT1/4 ports provide a robust connection for clamping and pressing applications.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The built-in magnet allows end-of-stroke detection via CMSG/DMSG sensors, confirming the clamp is fully engaged before a machining cycle starts.
Uses the 100 mm stroke to divert parts on a conveyor. Magnetic sensors provide positive gate-open and gate-closed signals to the PLC.
Applies 628 N of consistent force for sample preparation. The standard TPU seals operate reliably in clean, room-temperature environments.
Choose the SC40 bore when 628 N at 0.5 MPa meets your load requirement. If you need more force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore (402 N at 0.5 MPa) may suffice. The built-in magnet makes this cylinder ready for sensor integration without needing external brackets.
For a direct replacement, match five key points: 40 mm bore, 100 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting style. This tie-rod cylinder is shorter than an ISO 15552 profile, so it is not dimensionally interchangeable with those types.
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 reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. Only replace another AirTAC SC40 cylinder or a tie-rod cylinder with identical bore, stroke, port, and mounting dimensions.
