About the Airtac SC100 Standard Cylinder SC100X700STC
The SC100X700STC is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa), ideal for medium-heavy automation tasks requiring a long 700 mm linear stroke. This model includes a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) pivot mount, supplied with the TCM1 bracket, allowing the cylinder to swing through an arc during operation.
With a 25 mm diameter piston rod, PT1/2 ports, and a 29 mm adjustable air cushion, the SC100X700STC decelerates high-inertia loads smoothly at end-of-stroke. The body length A is 188 mm, giving an approximate total extended length of 888 mm. Operating on filtered air from 0.15 to 1.0 MPa, this genuine AirTAC cylinder uses standard TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X700STC Is Used
Conveyor Diverter Gates
The 700 mm stroke and high push force of the SC100X700STC reliably actuates heavy diverter gates on wide conveyor lines, while the trunnion mount allows the cylinder body to pivot as the gate swings.
Welding Fixture Clamping
Delivers 7068 N of clamping force at 0.9 MPa for securing large fabrications in welding jigs. The built-in magnet enables end-of-stroke confirmation via reed sensors for automated cycle start.
Agricultural Equipment Actuation
Ideal for long-throw actuation on harvesters or spreaders, such as opening discharge chutes. The trunnion mount handles the pivoting motion, and the TPU seals perform reliably in dusty, ambient-temperature environments.
Is the Airtac SC100 Standard Cylinder SC100X700STC the Right Cylinder?
Select the SC100 bore when your application requires between 3927 N (push at 0.5 MPa) and 7068 N (push at 0.9 MPa). For lower force needs, step down to the SC80 bore (2513 N at 0.5 MPa) for a smaller footprint and faster cycling. For higher demands, the SC125 bore provides 6136 N at 0.5 MPa. At 700 mm stroke, the rod is fully supported within the barrel, but external side loads must be managed with an external guide or rod support to prevent bending and premature bearing wear.
For a direct replacement, match these five points: 100 mm bore, 700 mm stroke, PT1/2 port thread, centre trunnion (TC) mounting with F-SC100TC bracket, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders.

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 SC100X700STC FAQ
At the standard 0.5 MPa operating pressure, 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 SC100X700STC is a double-acting cylinder and will not hold position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end to reduce impact. For load holding, you must add an external rod lock or a pilot-operated check valve.
