About the Airtac SC100 Standard Cylinder SC100X990S
The AirTAC SC100X990S is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa operating pressure. With a 100 mm bore and a long 990 mm stroke, it uses a 25 mm diameter piston rod with M20x1.5 male threads and PT1/2 ports. The built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing.
This model falls within the standard stroke range for the SC100 bore (max 1500 mm). The body length A is 188 mm, making the total extended length approximately 1178 mm. Adjustable pneumatic cushioning at both ends (29 mm cushion length) decelerates the piston near stroke end to reduce impact. Operating pressure is 0.15-1.0 MPa with air filtered to 40 µm, and the standard TPU/NBR seals work from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X990S Is Used
Long-Reach Material Transfer
The 990 mm stroke moves pallets or bins across conveyor gaps in distribution centers. The built-in magnet enables end-of-stroke confirmation via CMSG sensors for automated sortation control.
Press-Feed Automation
Delivers 3927 N at 0.5 MPa to push heavy sheet metal blanks into a stamping press. The adjustable cushion absorbs impact at full extension, protecting tooling and reducing cycle noise.
Sawmill Log Positioning
Positions logs or heavy timber on infeed decks. The 25 mm rod and tie-rod construction handle repetitive thrust, while the magnet allows sensor-based stroke verification in dusty environments.
Is the Airtac SC100 Standard Cylinder SC100X990S the Right Cylinder?
The SC100 bore generates 3927 N push at 0.5 MPa—a significant step up from the SC80 (2513 N) and below the SC125 (6136 N). If your load requires more force, step up to the SC125; if speed is the priority and force can be lower, the SC80 may suit. For this 990 mm stroke, ensure the rod is not subjected to side loading: a 25 mm rod extended nearly a meter can bend under lateral force. Use an external linear guide or a guided cylinder variant if side loads are present.
For replacement, match five points: 100 mm bore, 990 mm stroke, PT1/2 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting (no accessory bracket). This is a tie-rod cylinder, not an ISO 15552 profile unit—it is shorter and not dimensionally interchangeable with ISO 15552 cylinders. Only the SC125–SC250 bores are classed as ISO 6430.
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 SC100X990S 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, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf. Actual force depends on your supply pressure and piping.
No. The SC100X990S is a double-acting pneumatic cylinder and will not hold position if pressure is exhausted or the directional valve centers. The piston can drift or drop. For load holding without live pressure, add a pilot-operated check valve or an external mechanical rod brake.
