About the Airtac SC100 Standard Cylinder SC100X975
The AirTAC SC100X975 is a double-acting tie-rod cylinder delivering a substantial 3927 N push force at 0.5 MPa (7068 N at the maximum operating pressure of 0.9 MPa). With a 100 mm bore and a 975 mm stroke, this model is built for applications requiring high force over a long linear travel distance. The 25 mm diameter piston rod and 29 mm adjustable air cushion at each end ensure robust performance and smooth end-of-stroke deceleration.
This cylinder uses a PT1/2 port and an M20x1.5 rod thread, with a body length (A) of 188 mm. The total extended length is approximately 1163 mm. Operating on filtered air from 0.15 to 1.0 MPa, the standard TPU seals provide a temperature range of -20 to +70 °C. As a genuine AirTAC SC series unit, it is a reliable, high-value choice for demanding industrial automation tasks.

Where the Airtac SC100 Standard Cylinder SC100X975 Is Used
Long-Stroke Material Pusher
The 975 mm stroke is ideal for pushing heavy pallets or large components across a wide conveyor or transfer station, leveraging the 3927 N force at 0.5 MPa.
Heavy-Duty Clamping & Forming
Delivers up to 7068 N of force at 0.9 MPa for pressing, clamping, or forming operations in automotive or metal fabrication jigs where a long retraction is needed for part clearance.
Large Gate or Diverter Actuation
Provides the high force and extended reach necessary to open and close large hopper gates, diverters, or chutes in bulk material handling and agricultural processing lines.
Is the Airtac SC100 Standard Cylinder SC100X975 the Right Cylinder?
Select the SC100X975 when your application needs the 3927 N push force of a 100 mm bore at standard plant pressure. If your load requires less force, consider stepping down to an 80 mm bore (2513 N at 0.5 MPa) for a more compact and economical solution. For even greater force, the 125 mm bore provides 6136 N at the same pressure.
For a stroke of 975 mm, careful attention to side loading is critical. The long, unsupported 25 mm rod is susceptible to bending under radial forces. Always ensure the load is guided externally on linear rails, or consider using a guided cylinder, to prevent premature rod bearing and seal wear. When replacing an existing cylinder, match these five points exactly: 100 mm bore, 975 mm stroke, PT1/2 port thread, basic (no) mounting, and confirm if a magnet is required.
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 SC100X975 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 SC100X975 is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift. For load holding, you must add an external rod lock or a pilot-operated check valve.
