About the Airtac SC100 Standard Cylinder SC100X235STC
The SC100X235STC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa, making it a powerful actuator for medium-to-heavy industrial tasks. Its 235 mm stroke is paired with a 25 mm diameter piston rod and a 29 mm adjustable air cushion at each end, effectively decelerating the 100 mm bore piston to reduce end-of-stroke impact.
This configuration includes a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise, non-contact position feedback along the barrel. The TC centre trunnion mount (supplied with the TCM1 bracket, part code F-SC100TC) allows the cylinder to pivot, accommodating swinging or articulating loads in constrained spaces.

Where the Airtac SC100 Standard Cylinder SC100X235STC Is Used
Conveyor Diverter Gates
The 3927 N push force at 0.5 MPa easily actuates heavy diverter gates on high-throughput conveyor systems, while the trunnion mount absorbs the pivoting motion.
Clamping & Fixturing
Provides up to 7068 N of clamping force at 0.9 MPa for holding large weldments or castings during machining, with magnetic sensors confirming clamp engagement.
Press & Forming Assist
Ideal as a stripping or ejection cylinder in medium-duty presses, where the 29 mm cushion softens the return stroke and the trunnion mount simplifies alignment.
Is the Airtac SC100 Standard Cylinder SC100X235STC the Right Cylinder?
For applications needing slightly less force, stepping down to an 80 mm bore reduces push force to 2513 N at 0.5 MPa, while a 125 mm bore increases it to 6136 N if the load demands more power. The 235 mm stroke is well within the 1500 mm maximum standard stroke for the 100 mm bore, ensuring standard lead times.
When replacing an existing cylinder, match five key points: 100 mm bore, 235 mm stroke, PT port thread, the TC centre trunnion mounting style, and the -S magnet option for sensor compatibility. For strokes over 300 mm, always assess side-loading on the 25 mm rod; external guides are recommended to prevent rod bending and premature bearing wear.
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 SC100X235STC FAQ
At the standard operating pressure of 0.7 MPa, the push force is 5497 N and the pull force is 3681 N (at 0.5 MPa). The maximum theoretical push force at 1.0 MPa is 801 kgf. These values are based on the 100 mm bore and 25 mm rod diameter.
No. The SC100X235STC is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the end of its stroke to reduce impact; it is not a locking or holding brake. For load-holding applications, you must add a pilot-operated check valve or an external mechanical rod lock.
