About the Airtac SC40 Standard Cylinder SC40X175SH
The AirTAC SC40X175SH is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 175 mm stroke, delivering a push force of 628 N at 0.5 MPa (up to 1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke positioning tasks.
This model is equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling contactless position sensing along the tie-rod barrel. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot environments like autoclaves or foundry equipment where standard seals would degrade.

Where the Airtac SC40 Standard Cylinder SC40X175SH Is Used
Hot-Zone Actuation
Viton seals allow this cylinder to operate reliably in 0–150°C environments such as autoclave doors, steam valves, or drying oven conveyors where standard seals would fail.
Sensor-Controlled Sorting
The built-in magnet enables CMSG/DMSG sensors to detect piston position for precise end-of-stroke or mid-stroke confirmation in automated sorting and pick-and-place systems.
Packaging Machine Pusher
With 628 N of force at standard shop air, it reliably pushes cartons or products onto a packaging line, and the adjustable cushion reduces noise and impact at the end of travel.
Is the Airtac SC40 Standard Cylinder SC40X175SH the Right Cylinder?
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. If a shorter overall length is required, the 32 mm bore SC32 series offers 402 N at 0.5 MPa. This 175 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore.
To ensure a direct replacement, match five key points: bore (40 mm), stroke (175 mm), PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. When ordering mounting accessories separately, use the F-SC40 prefix (e.g., F-SC40LB for a foot mount).
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC40 Standard Cylinder SC40X175SH FAQ
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. 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 profile cylinder, so it is not dimensionally interchangeable. It is a direct match only for another AirTAC SC40 tie-rod cylinder with the same bore, stroke, PT port, magnet option, and Viton seals.
