About the Airtac SC100 Standard Cylinder SC100X55S
The SC100X55S is a double-acting AirTAC SC tie-rod cylinder with a 100 mm bore and 55 mm stroke, delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 25 mm diameter piston rod and 29 mm adjustable air cushion provide smooth end-of-stroke deceleration for consistent cycling.
This model includes the -S suffix for a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The standard PT 1/2 port and TPU seals suit filtered-air applications from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X55S Is Used
Part Stops & Gates
The 55 mm stroke and 3927 N push force at 0.5 MPa make this cylinder ideal for compact part stops and diverter gates on conveyor lines, with the built-in magnet enabling end-of-stroke sensor confirmation.
Clamping & Pressing
Short-stroke, high-force clamping in machining fixtures or assembly jigs. The sensor-ready barrel allows PLC verification of clamp engagement before a cycle starts.
Palletising Pushers
Pushing cartons or totes onto a pallet layer with a controlled 55 mm stroke. The adjustable cushion protects the cylinder and load from impact damage at higher cycle rates.
Is the Airtac SC100 Standard Cylinder SC100X55S the Right Cylinder?
For higher force, step up to the 125 mm bore SC125 series (6136 N push at 0.5 MPa); for a lighter, more compact actuator, the 80 mm bore SC80 delivers 2513 N at 0.5 MPa. When replacing an existing cylinder, match five points: 100 mm bore, 55 mm stroke, PT 1/2 port thread, the built-in magnet (-S), and any mounting accessory.
At this short 55 mm stroke, side loading is rarely a concern, but always align the rod with the load axis to prevent premature rod bearing and seal wear.
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 SC100X55S 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 reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes. The -S suffix in SC100X55S means a magnet is built into the piston, so AirTAC CMSG, DMSG, or EMSG sensors can be clamped directly onto the tie-rod barrel for non-contact position sensing.
