About the Airtac SC100 Standard Cylinder SC100X15STC
The SC100X15STC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a compact 15 mm stroke. This configuration produces a push force of 3927 N at 0.5 MPa (7068 N at 0.9 MPa), making it a compact powerhouse for short-throw clamping and ejecting tasks.
It features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors on the barrel, and ships with a centre trunnion mount (TC) including the TCM1 bracket (F-SC100TC) for pivoting applications. The 25 mm diameter rod, PT1/2 ports, and 29 mm adjustable air cushion ensure reliable deceleration in a tight envelope.

Where the Airtac SC100 Standard Cylinder SC100X15STC Is Used
Short-Stroke Clamping
The 3927 N force at 0.5 MPa and 15 mm stroke provide rapid, high-force clamping for CNC fixtures, welding jigs, and assembly stations.
Part Ejection
Delivers a sharp, controlled push to eject parts from injection molds or stamping dies, with sensor confirmation via the built-in magnet.
Pivoting Actuator
The centre trunnion mount allows the cylinder to pivot, making it suitable for actuating levers, diverters, or compact press mechanisms.
Is the Airtac SC100 Standard Cylinder SC100X15STC the Right Cylinder?
For higher force in a similar footprint, the SC125 series steps up to 6136 N at 0.5 MPa. If you need a longer stroke, the SC100 standard range extends to 1500 mm. This model's short 15 mm stroke is ideal for clamping fixtures where speed and repetition are key.
When replacing, match five points: 100 mm bore, 15 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC100X15STC FAQ
At the standard 0.5 MPa operating pressure, it delivers 3927 N pushing and 3681 N pulling. At the maximum 0.9 MPa, the push force reaches 7068 N.
No. The SC100 is a double-acting cylinder and will drift or drop if pressure is lost or the valve is centred. A pilot-operated check valve or external rod lock is required for static load holding.
