About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-10
The AirTAC SAIJ100X300-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 290-300 mm usable travel window, allowing you to dial back the 300 mm nominal stroke by up to 10 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles substantial workloads while maintaining a standard G1/2 port and M20x1.5 rod thread.
This extruded aluminum barrel design includes sensor grooves on both sides for flexible switch placement. The rear stopper mechanism fine-tunes the end position without swapping the cylinder, though it acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-10 Is Used
End-Position Tuning
Dial in the exact 290-300 mm travel distance during machine setup without adding external stopper blocks.
Product Changeover
Quickly adjust the retract stop for slightly different product sizes on a packaging line.
Heavy Assembly
Leverage 3927 N of push force at 0.5 MPa for pressing and clamping tasks requiring fine end-stop control.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-10 the Right Cylinder?
Choose this 100 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is insufficient but a 125 mm bore (6136 N) is excessive. The 10 mm adjustment range is ideal for product changeovers requiring slight end-position shifts. For load-holding without live air, consider the SAIL or BSAI series, as the SAIJ adjuster is not a lock. To match this ISO 15552 replacement, specify: 100 mm bore, 300 mm stroke, PT port thread, carbon steel rod, and no magnet (-S omitted).
Because the 300 mm stroke is relatively long, ensure adequate external guidance to prevent rod side-loading, even with the robust 25 mm diameter rod. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 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 SAIJ100 Adjustable Cylinder SAIJ100X300-10 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10 mm. This provides a usable travel window of 290-300 mm, enabling fine-tuning at commissioning without replacing the cylinder.
At 0.5 MPa, the 100 mm bore provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
