About the Airtac SC100 Standard Cylinder SC100X340STC
The AirTAC SC100X340STC is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 340 mm stroke, it uses a 25 mm diameter piston rod and PT1/2 ports, making it a robust choice for medium-to-heavy linear actuation tasks.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and the TC suffix supplies a centre trunnion pivot (F-SC100TC) with the TCM1 bracket, allowing the cylinder to swing through an arc. The body length A is 188 mm, and the adjustable air cushion (29 mm) decelerates the piston smoothly at end-of-stroke.

Where the Airtac SC100 Standard Cylinder SC100X340STC Is Used
Conveyor Diverters
Pneumatic gate or pusher on a packaging line. The 3927 N push force at 0.5 MPa easily shifts cartons, and the centre trunnion mount lets the cylinder pivot as the diverter blade moves through its arc.
Clamping & Fixturing
Heavy-duty workpiece clamping in a machining centre. The 340 mm stroke provides ample retraction for part loading, while the magnet enables clamp/unclamp confirmation via barrel-mounted sensors.
Press & Forming Assist
Material pressing or forming station requiring 7068 N at 0.9 MPa. The adjustable cushion handles the high cycle rate, and the trunnion mount absorbs the slight angular movement of the press linkage.
Is the Airtac SC100 Standard Cylinder SC100X340STC the Right Cylinder?
Choose the SC100 when your application needs roughly 3927 N at 0.5 MPa. If you can accept less force, stepping down to an SC80 bore saves space and weight (2513 N at 0.5 MPa). For higher force demands, the SC125 bore provides 6136 N at the same pressure. Always match five points when replacing: bore (100 mm), stroke (340 mm), PT port thread, TC centre trunnion mounting, and the built-in magnet for sensors.
At a 340 mm stroke, the 25 mm rod is well-supported inside the barrel, but avoid direct side loads on the rod end. If the load applies any lateral force, use an external linear guide or rod-alignment coupler to prevent bending stress on the rod bearing and premature seal 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 SC100X340STC FAQ
At the standard operating pressure of 0.7 MPa, the push force is 5497 N and the pull force is 3681 N. The maximum push force at 0.9 MPa is 7068 N. These values assume a static load; always apply a safety factor for dynamic applications.
Yes, if the original is an AirTAC SC100 tie-rod cylinder with the same 340 mm stroke, PT1/2 ports, centre trunnion (TC) mount, and built-in magnet. The SC series is not dimensionally interchangeable with ISO 15552 cylinders, so verify the body length A (188 mm) and trunnion position match your existing setup.
