Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-30S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 750mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-30S
The AirTAC SAIJ100X750-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa) and features a 25 mm carbon steel rod with an M20x1.5 thread. The built-in rear stopper allows you to fine-tune the travel window from 720 to 750 mm, giving you precise end-position control during commissioning without needing external stops.
This adjustable model features a -S magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a mechanical stop to set the travel end, so it will not hold the load if air pressure drops; for fail-safe load holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-30S Is Used
Machine Changeover
Dial in the 720-750 mm end-stop during product size transitions without physically swapping the cylinder or adding external shims.
End-Position Tuning
Fine-tune the final retract position at commissioning to hit exact mechanical tolerances using the rear adjusting screw.
Heavy-Duty Positioning
Move heavy jigs with 3927 N of push force at 0.5 MPa while relying on the 25 mm rod to handle high side loads.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-30S the Right Cylinder?
Choose this 100 mm bore when 80 mm falls short (delivering 2513 N at 0.5 MPa) but you want to avoid the larger 125 mm footprint. The 30 mm adjustment window is ideal for product changeovers, letting you dial in the exact end-stop on the fly rather than swapping cylinders. Because this is a 750 mm stroke, an external guide is highly recommended to prevent excessive side-loading on the 25 mm rod.
To replace this ISO 15552 cylinder, match the 100 mm bore, 750 mm stroke, 30 mm adjustment, PT G1/2 port, and the -S magnet. It shares the standard SAI footprint but omits the FB, CA, CB, and CR mounts.
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 SAIJ100X750-30S FAQ
It provides 3927 N of push force and 3681 N of pull force at 0.5 MPa, scaling up to 7068 N push at 0.9 MPa. The operational speed range is 30-800 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 750 mm down to 720 mm. It sets the end position but does not lock the load without live air pressure.
