About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-40S
The AirTAC SAIJ100X750-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 710 to 750 mm, allowing you to dial in the exact retract end-position during commissioning without adding external stops. Delivering 3927 N of push force at 0.5 MPa, it is built for heavy-duty tasks.
This model includes a -S magnet for position sensing with AirTAC CMSE reed or DMSE electronic switches. It uses a standard carbon steel piston rod and a PT tapered G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-40S Is Used
Product Size Changeover
Quickly reconfigure the retract distance on packaging lines when switching to different box sizes, using the 710-750 mm window to set new end stops without changing hardware.
Machine Setup Tuning
Fine-tune the end-of-stroke position during initial commissioning to dial in exact pressing or lifting distances, absorbing mechanical tolerances via the rear adjuster.
Heavy Material Handling
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or workpieces, relying on the robust 25 mm carbon steel rod for demanding industrial cycles.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-40S the Right Cylinder?
Choose this 100 mm bore when you need more thrust than the 80 mm bore (which yields 2513 N push at 0.5 MPa) but want to avoid stepping up to the 125 mm class. The adjustable 710-750 mm travel is ideal for product changeovers on a line, letting you fine-tune the retract distance on the fly instead of physically swapping a fixed-stroke SAI cylinder.
Because the 750 mm stroke is long, an external guide is recommended to prevent rod side-load damage, as the 25 mm rod and M20x1.5 thread can only compensate so much. Note that the rear adjuster acts as a travel stop, not a lock; the SAIJ does not hold loads without live air, so for fail-safe holding you should look at the SAIL or BSAI series. To replace an ISO 15552 cylinder, match the 100 mm bore, 750 mm stroke, 40 mm adjustment, PT G1/2 port, and -S magnet.
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 SAIJ100X750-40S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the effective travel from the 750 mm nominal stroke down to 710 mm. This creates a 710-750 mm usable window for fine-tuning the retract end-position without swapping the cylinder.
