About the Airtac SC100 Standard Cylinder SC100X820SCB
The AirTAC SC100X820SCB is a double-acting tie-rod cylinder delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With an 820 mm stroke and a 25 mm diameter piston rod, this model is built for linear applications that require a long reach combined with a high force output.
This specific configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, and a rear double clevis mount (CB, part F-SC100CB) for pivoting attachment. The body length A is 188 mm, and the adjustable pneumatic cushion (29 mm) decelerates the piston smoothly at each end of the stroke.

Where the Airtac SC100 Standard Cylinder SC100X820SCB Is Used
Long-Reach Material Transfer
The 820 mm stroke and 3927 N push force at 0.5 MPa efficiently transfer heavy components between distant conveyor stations or work cells.
Agricultural Equipment Actuation
Pivots a heavy chute or gate on a harvester or spreader using the rear clevis mount, with the built-in magnet providing end-of-stroke position feedback.
Heavy-Duty Clamping Fixture
Applies up to 7068 N of clamping force at 0.9 MPa in a large welding or assembly fixture, with sensors confirming the jaw is fully closed.
Is the Airtac SC100 Standard Cylinder SC100X820SCB the Right Cylinder?
Choose the SC100 when your application requires around 4000 N of force at standard plant pressure. If your load is lighter, stepping down to an 80 mm bore reduces the push force to 2513 N at 0.5 MPa. For this 820 mm stroke, ensure the rod is protected from side loads; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
For a direct replacement, match these five points: 100 mm bore, 820 mm stroke, PT port thread, CB rear double clevis mounting, and the -S magnet for sensor compatibility. This is a genuine AirTAC SC tie-rod cylinder, which is shorter than an ISO 15552 profile and not dimensionally interchangeable with it.
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 SC100X820SCB FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a load safely without live pressure, you must add a mechanical lock, an external rod brake, or a pilot-operated check valve.
