About the Airtac SC100 Standard Cylinder SC100X73
The AirTAC SC100X73 is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and a compact 73 mm stroke, it provides a robust linear thrust in a relatively short package, making it ideal for clamping and pressing operations where space is limited.
This model features a 25 mm diameter piston rod with M20x1.5 male threads and PT1/2 ports. The total body length is 188 mm, and the adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly at end-of-stroke. Standard TPU seals provide an operating range of -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X73 Is Used
Heavy Clamping
The 3927 N force at 0.5 MPa makes the SC100X73 perfect for pneumatic toggle clamps and vise fixtures requiring high holding power in a short stroke.
Product Rejection Gates
Ideal for fast-acting diverter gates on conveyor lines, using the 73 mm stroke to push defective items off the belt with significant force.
Press-Fit Assembly
Delivers a controlled 7068 N peak thrust at 0.9 MPa for pressing bearings, bushings, or pins into housings in automated assembly cells.
Is the Airtac SC100 Standard Cylinder SC100X73 the Right Cylinder?
The SC100 bore sits in the high-force mid-range. If 3927 N at 0.5 MPa is more thrust than needed, stepping down to an 80 mm bore reduces push force to 2513 N. For strokes of this length, the standard tie-rod construction provides excellent rigidity, but always ensure the load is aligned axially with the rod to prevent side-load bending.
When replacing an existing unit, match five key points: 100 mm bore, 73 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and the absence of a magnet. This ensures a direct dimensional and performance swap.
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 SC100X73 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 3927 N. The pull force on the retract stroke is 3681 N due to the rod area. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
No. The AirTAC SC series is a tie-rod cylinder and is shorter in overall length than a standard ISO 15552 profile cylinder. It will not be dimensionally interchangeable. Only replace with another AirTAC SC tie-rod cylinder matching the 100 mm bore, 73 mm stroke, and PT port thread.
