About the Airtac SC100 Standard Cylinder SC100X40STC
The SC100X40STC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa, making it a compact powerhouse for short-stroke clamping and pressing tasks. Its 100 mm bore houses a 25 mm diameter piston rod with PT1/2 ports, and the 40 mm stroke keeps the overall extended length to just 228 mm (body length A=188 mm + stroke).
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (-TC suffix) with the TCM1 bracket for pivoting applications. The adjustable air cushion (29 mm length) decelerates the piston smoothly, protecting end caps during high-cycle operation.

Where the Airtac SC100 Standard Cylinder SC100X40STC Is Used
Short-Stroke Clamping
The 40 mm stroke and 3927 N force at 0.5 MPa make this cylinder ideal for pneumatic clamping fixtures in machining centres, where rapid, high-force clamping and unclamping is required within a compact envelope.
Pivoting Press Mechanism
With the centre trunnion mount, the SC100X40STC can pivot to follow an arc path in a toggle press or stamping mechanism. The built-in magnet allows end-of-stroke sensing to confirm each press cycle.
Part Ejection Gate
Used as a short-throw actuator for a diverter gate on a conveyor line. The 3927 N push force easily moves heavy parts, while the trunnion mount accommodates the slight angular movement of the gate linkage.
Is the Airtac SC100 Standard Cylinder SC100X40STC the Right Cylinder?
For higher force requirements, stepping up to the SC125 bore provides 6136 N of push at 0.5 MPa. If a shorter body is needed, the SC80 bore offers 2513 N at 0.5 MPa with a 182 mm body length. The centre trunnion (F-SC100TC) allows the cylinder to swing during operation, ideal for applications where the load path is not perfectly linear.
When replacing this cylinder, match five key points: 100 mm bore, 40 mm stroke, PT1/4 port thread, centre trunnion mounting (TC with TCM1 bracket), and the built-in magnet (-S) for sensor compatibility. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC100 models with identical mounting.
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 SC100 Standard Cylinder SC100X40STC FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder produces 5497 N of push force. The maximum push force at 0.9 MPa is 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, allowing you to directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel tie-rods to detect piston position without any additional brackets.
