About the Airtac SC100 Standard Cylinder SC100X55
The SC100X55 is a double-acting tie-rod cylinder delivering 3927 N push force at 0.5 MPa and up to 7068 N at 0.9 MPa operating pressure. Its 100 mm bore and 55 mm stroke suit short-throw clamping, pressing, and ejector tasks where a compact extended length of approximately 243 mm fits tight machine envelopes.
This model uses a 25 mm diameter piston rod with M20x1.5 threads and PT1/2 ports. The adjustable air cushion (29 mm length) decelerates the piston near stroke end to reduce impact. As a genuine AirTAC SC series unit, it is built with a TPU/NBR seal package rated for -20 to +70 °C and filtered-air operation.

Where the Airtac SC100 Standard Cylinder SC100X55 Is Used
Short-Stroke Clamping
Generates up to 7068 N at 0.9 MPa for fixture clamping and workpiece holding in machining centres, with a 55 mm stroke that cycles quickly.
Press-Fit Assembly
Delivers controlled force for bearing or bushing insertion. The adjustable cushion protects tooling at the end of the 55 mm advance.
Part Ejection
Pushes finished parts off a conveyor or out of a die with a short, powerful 55 mm stroke, integrating easily with PT1/2 pneumatic lines.
Is the Airtac SC100 Standard Cylinder SC100X55 the Right Cylinder?
For higher force at the same pressure, step up to the SC125 bore (6136 N at 0.5 MPa); for a lighter, more compact solution, the SC80 bore provides 2513 N at 0.5 MPa. The 55 mm stroke is within the standard range, so no special lead time applies.
When replacing, match five points: 100 mm bore, 55 mm stroke, PT1/2 port thread, basic (no mounting accessory), and no magnet. This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC100X55 FAQ
At 0.7 MPa supply pressure, the SC100X55 double-acting cylinder produces 5497 N of push force on the piston. The pull force at the same pressure is 3681 N, accounting for the 25 mm rod area.
This specific model code (SC100X55) does not include the -S magnet option, so the piston does not carry a magnet and reed/solid-state sensors cannot be used. For sensor-ready position detection, order the SC100X55-S variant instead.
