About the Airtac SC100 Standard Cylinder SC100X990SCB
The AirTAC SC100X990SCB is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and a long 990 mm stroke, this model is built for applications requiring substantial linear thrust over a significant travel distance.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a rear double clevis mount (CB, part F-SC100CB) for pivoting installation. The 25 mm diameter piston rod and 29 mm adjustable air cushion provide smooth deceleration, while the PT1/2 port supplies the operating flow. The total extended body length is approximately 1178 mm.

Where the Airtac SC100 Standard Cylinder SC100X990SCB Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or steel sheets across a 990 mm span on a transfer table, using the rear clevis mount to accommodate the pivoting motion of the linkage.
Press-Frame Ejection
Ejects large molded parts from a 100-ton press with 7068 N of force at full pressure, with the magnetic piston confirming full extension and retraction.
Diverter Gate Actuation
Operates a large diverter gate in a gravity chute, where the CB clevis allows the cylinder body to swing as the gate opens and closes over the long stroke.
Is the Airtac SC100 Standard Cylinder SC100X990SCB the Right Cylinder?
For higher force requirements, step up to the SC125 bore (6136 N at 0.5 MPa). If a shorter, more compact solution is acceptable, the SC80 bore provides 2513 N at 0.5 MPa. At a 990 mm stroke, the unsupported rod length is significant; external guides or a self-guided cylinder are strongly recommended to prevent rod bending and seal wear from side loads.
To ensure a correct drop-in replacement, match five key points: 100 mm bore, 990 mm stroke, PT1/2 port thread, the CB rear double clevis mounting accessory, and the -S built-in magnet for sensor compatibility.
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 SC100X990SCB 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 SC100 is a double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. To hold a load safely without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
