About the Airtac SC100 Standard Cylinder SC100X1250S
The SC100X1250S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a long 1250 mm stroke and a factory-installed magnet. At 0.5 MPa it generates 3927 N pushing force and 3681 N pulling force, rising to 7068 N push at the 0.9 MPa maximum operating pressure. The 25 mm diameter piston rod and 29 mm adjustable air cushion help manage end-of-stroke deceleration even at this extended reach.
This model includes the -S magnet option, so CMSG/DMSG/EMSG reed and solid-state sensors clamp directly onto the barrel for non-contact position sensing. The total extended body length is approximately 1438 mm (188 mm body length A plus 1250 mm stroke). Standard PT 1/2 ports and TPU seals with a -20 to +70 °C operating range complete the specification.

Where the Airtac SC100 Standard Cylinder SC100X1250S Is Used
Pallet Transfer Lines
The 1250 mm stroke moves pallets across wide conveyor gaps. The built-in magnet enables end-of-stroke confirmation sensors to sequence downstream equipment reliably.
Long-Reach Material Pushers
Pushes heavy bins or sheet metal stacks off a production line. The 3927 N force at 0.5 MPa handles substantial loads, while the 29 mm cushion absorbs impact quietly.
Large-Format Woodworking Clamps
Applies clamping pressure across wide glue-up tables. The -S magnet allows position monitoring to verify full clamp engagement before a CNC cycle starts.
Is the Airtac SC100 Standard Cylinder SC100X1250S the Right Cylinder?
Choose the SC100 when your application needs around 3927 N of push force at standard plant air pressure. If you can work with roughly 2513 N, stepping down to an SC80 reduces weight and air consumption. For strokes of 1250 mm, always check side-load conditions—a rod this long can bend under off-axis force. Use an external linear guide or a guided-cylinder assembly to protect the rod bearing and extend seal life.
For a direct replacement, match five points: 100 mm bore, 1250 mm stroke, PT 1/2 ports, the built-in magnet (-S), and the basic (no bracket) mounting configuration. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC100 of the same stroke and options.
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 SC100X1250S FAQ
At 0.5 MPa (approx. 73 psi) the cylinder pushes with 3927 N and pulls with 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical force at 1.0 MPa is 801 kgf, but the cylinder is rated only to 1.0 MPa.
No. The SC100 is a standard double-acting cylinder—it does not lock or hold position when air is exhausted or the directional valve is centered. For load-holding applications, add a pilot-operated check valve or an external rod brake.
