About the Airtac SC100 Standard Cylinder SC100X720S
The SC100X720S is a double-acting single-rod pneumatic cylinder with a 100 mm bore and 720 mm stroke, factory-equipped with a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed and solid-state sensors clip directly onto the barrel for contactless position sensing. At 0.5 MPa it generates 3927 N pushing force, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N — a force class suited to heavy pressing, clamping, and lifting fixtures.
This tie-rod cylinder uses a 25 mm diameter hard-chrome-plated rod with M20×1.5 male threads and PT1/2 ports. The adjustable air cushion at each end (29 mm cushion length) decelerates the piston smoothly, and the body length A is 188 mm, giving an approximate extended length of 908 mm. Operating range is -20 to +70 °C with the standard TPU/NBR seals, and the speed range is 30-800 mm/s. The 720 mm stroke is within the 1500 mm maximum standard stroke for bore 100.

Where the Airtac SC100 Standard Cylinder SC100X720S Is Used
Pallet & Container Handling
The 3927 N push force at 0.5 MPa moves heavy pallets or tote bins through 720 mm of travel in logistics and distribution centres. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors.
Heavy-Duty Clamping
With 7068 N available at 0.9 MPa, this cylinder provides secure clamping for large weldments or structural assemblies. The adjustable cushion protects tooling by absorbing impact at the end of the 720 mm stroke.
Long-Stroke Part Transfer
The 720 mm stroke transfers large components between conveyor lanes or machining stations. The tie-rod construction allows straightforward maintenance, and the magnet-equipped barrel simplifies sensor integration for automation controllers.
Is the Airtac SC100 Standard Cylinder SC100X720S the Right Cylinder?
For a 100 mm bore at 0.5 MPa, push force is 3927 N. If your load requires less force, stepping down to an 80 mm bore (2513 N push at 0.5 MPa) can reduce air consumption and footprint; for higher force, the 125 mm bore delivers 6136 N at the same pressure. With a 720 mm stroke, the rod is extended significantly — ensure side loads are minimal or add an external linear guide, because a long unsupported 25 mm rod is vulnerable to bending under off-axis forces.
When replacing an existing cylinder, match five points: 100 mm bore, 720 mm stroke, PT1/2 port thread, the built-in magnet for sensor mounting, and the basic (no-bracket) mounting style. This SC model is a tie-rod cylinder and is shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable with ISO 15552 types — only direct SC-to-SC replacement is assured.

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 SC100X720S FAQ
At 0.5 MPa the push force is 3927 N and pull force is 3681 N. At 0.7 MPa push force rises to 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf. These values assume a clean, filtered air supply at 40 µm.
No. The SC100X720S is a double-acting cylinder that requires live air pressure on one side of the piston to maintain position. If pressure is lost or the directional valve centres, the piston will drift. For load holding without pressure, add a pilot-operated check valve or an external rod brake — the adjustable air cushion only decelerates the piston near stroke end and does not lock it.
