About the Airtac SC100 Standard Cylinder SC100X550STC
The SC100X550STC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the 0.9 MPa maximum operating pressure. With a 100 mm bore and 550 mm stroke, this model uses a 25 mm diameter piston rod with M20x1.5 threads and PT1/2 ports, making it a robust choice for medium-to-heavy linear actuation tasks.
This configuration includes a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC suffix) supplied with the TCM1 bracket (F-SC100TC) for pivoting applications. The adjustable air cushion (29 mm length) decelerates the piston smoothly at end-of-stroke, protecting the end caps during high-cycle operation.

Where the Airtac SC100 Standard Cylinder SC100X550STC Is Used
Conveyor Diverter Gates
The 3927 N push force at 0.5 MPa easily actuates heavy diverter gates on wide conveyor systems, while the centre trunnion mount allows the cylinder body to pivot as the gate swings through its arc.
Clamping & Fixturing
Apply consistent, high clamping pressure for CNC machining fixtures or welding jigs. The built-in magnet enables end-of-stroke confirmation via CMSG sensors to interlock with machine safety circuits.
Press & Forming Assist
Delivers up to 7068 N at 0.9 MPa for light press-fit assembly or forming operations. The 29 mm adjustable cushion absorbs impact energy, reducing wear when the tooling bottoms out.
Is the Airtac SC100 Standard Cylinder SC100X550STC the Right Cylinder?
Select the SC100 when your application needs roughly 4000 N of force at standard plant air pressure; stepping down to an SC80 bore reduces push force to 2513 N at 0.5 MPa, while moving up to an SC125 provides 6136 N. For this 550 mm stroke, ensure the rod is not subjected to significant side loading—long, unsupported strokes on a 25 mm rod can experience bending moments. Use an external linear guide or a guided cylinder if the load is not perfectly axial.
To replace an existing cylinder, match five points: 100 mm bore, 550 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC100TC bracket, and the built-in magnet for sensors. The SC is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile, so it is not a drop-in replacement for those types.
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 SC100X550STC FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf (7850 N push).
No. The SC100 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is exhausted or the directional valve centers, the piston can drift. For load holding, you must add a pilot-operated check valve or an external mechanical rod lock.
