About the Airtac SC100 Standard Cylinder SC100X800STC
The SC100X800STC is a double-acting tie-rod cylinder delivering a push force of 3927 N at 0.5 MPa (up to 7068 N at 0.9 MPa). With an 800 mm stroke and a 25 mm diameter rod, this model is built for linear transfer and clamping tasks requiring substantial force over a long reach.
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 TCM1 bracket F-SC100TC) that allows the cylinder to pivot during operation. The body length A is 188 mm, resulting in a total extended length of approximately 988 mm.

Where the Airtac SC100 Standard Cylinder SC100X800STC Is Used
Long-Stroke Part Transfer
The 800 mm stroke and 3927 N push force move heavy pallets or engine blocks between conveyor lines. The centre trunnion mount lets the cylinder body pivot, accommodating slight misalignments in the transfer path.
Automated Welding Fixtures
Clamps large fabrications with up to 7068 N of force at 0.9 MPa. The built-in magnet enables end-of-stroke confirmation via reed sensors, ensuring the fixture is fully closed before the welding cycle starts.
Vertical Lift & Tilt Gates
Operates a heavy tilt gate or diverter chute in bulk material handling. The trunnion mount handles the pivoting motion, while the adjustable air cushion decelerates the 25 mm rod smoothly at each end of the 800 mm stroke.
Is the Airtac SC100 Standard Cylinder SC100X800STC the Right Cylinder?
Choose the SC100 bore for applications needing around 3927 N of push force at standard plant pressure; if your load is lighter, stepping down to an SC80 (2513 N at 0.5 MPa) can reduce air consumption and physical size. For strokes of 800 mm, always check for side loads—long, unsupported rods can bend under lateral force. Use an external guide rail or a guided cylinder if the load is not perfectly axial.
For direct replacement, match five points: 100 mm bore, 800 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC100 of the same configuration.
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 SC100X800STC FAQ
At 0.5 MPa (approx. 73 psi), the cylinder produces 3927 N pushing and 3681 N pulling. 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 SC100X800STC is a double-acting cylinder that does not lock or hold position without live air pressure. If the load must be held stationary during a power loss or valve centre condition, you must add a pilot-operated check valve or an external mechanical rod brake.
