About the Airtac SC100 Standard Cylinder SC100X90STC
The SC100X90STC is a genuine AirTAC tie-rod cylinder delivering a substantial 3927 N of push force at 0.5 MPa, making it ideal for medium-stroke clamping and pressing tasks. With a 90 mm stroke and a 25 mm diameter piston rod, this double-acting unit provides robust linear motion for industrial automation.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion (TC) mount with the TCM1 bracket for pivoting applications. The standard PT1/2 ports and TPU seals handle filtered air from 0.15-1.0 MPa, with an adjustable air cushion to decelerate the 3927 N push force smoothly at end-of-stroke.

Where the Airtac SC100 Standard Cylinder SC100X90STC Is Used
Conveyor Diverters
The 3927 N push force at 0.5 MPa easily actuates heavy-duty diverters or gates on packaging lines, while the trunnion mount allows the cylinder body to pivot as it cycles.
Assembly Presses
Ideal for small pneumatic presses requiring a controlled 90 mm stroke, the adjustable cushion protects tooling from impact, and the magnet confirms full extension via a reed switch.
Welding Fixture Clamps
The centre trunnion mount lets this cylinder swing into position on a welding jig. The built-in magnet provides clamp-state feedback to the PLC for interlocking safety circuits.
Is the Airtac SC100 Standard Cylinder SC100X90STC the Right Cylinder?
For higher force needs, step up to the SC125 bore, which provides 6136 N at 0.5 MPa. If space is tight but you need less force, the SC80 bore offers 2513 N at the same pressure. The 90 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring standard lead times.
To guarantee a perfect replacement, match five points: 100 mm bore, 90 mm stroke, PT port thread, TC centre trunnion mount (F-SC100TC with TCM1 bracket), and the built-in magnet for sensor compatibility. Always guide the rod externally if side loads are present, even on shorter strokes, to prevent 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 SC100X90STC FAQ
At the standard 0.5 MPa operating pressure, this double-acting cylinder provides 3927 N pushing force and 3681 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC100 tie-rod cylinder with matching port thread, mounting, and magnet option.
