About the Airtac SC100 Standard Cylinder SC100X440S
The AirTAC SC100X440S is a double-acting single-rod pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore, 25 mm diameter piston rod, and a 440 mm stroke, it is built for demanding linear automation tasks that require substantial force over a mid-range travel distance.
This model features a built-in magnet (denoted by the -S suffix), allowing for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for precise, non-contact position feedback. The total extended body length is approximately 628 mm, and the adjustable pneumatic cushion at each end (29 mm length) decelerates the piston smoothly to absorb impact energy.

Where the Airtac SC100 Standard Cylinder SC100X440S Is Used
Pallet Stop & Transfer
Provides the high force needed to stop and transfer heavy pallets on conveyor lines, with magnetic sensors confirming the raised or lowered position.
Heavy-Duty Clamping
Applies up to 7068 N of clamping force at 0.9 MPa for securing large weldments or engine blocks in machining fixtures.
Bin Tilter & Dumper
Powers the tilt mechanism on large bin dumpers, where the 440 mm stroke provides the necessary arc of motion for complete discharge.
Is the Airtac SC100 Standard Cylinder SC100X440S the Right Cylinder?
Select the SC100 bore when your application needs a push force around 3927 N at standard 0.5 MPa shop air, stepping up from the 2513 N offered by the SC80 bore. For strokes of 300 mm or more, like this 440 mm unit, be mindful of side loading; the 25 mm rod can bend under high lateral forces, so an external guide or a guided cylinder is recommended to protect the rod bearing and seals. For a direct replacement, match five key points: 100 mm bore, 440 mm stroke, PT port thread, basic mounting (no bracket), and the built-in magnet (-S) 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 SC100X440S FAQ
At 0.5 MPa, the cylinder pushes with 3927 N and pulls with 3681 N. At 0.7 MPa, the push force increases to 5497 N, and at the maximum operating pressure of 0.9 MPa, it reaches 7068 N.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
