Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-75S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-75S 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 SAIJ100X750-75S
The AirTAC SAIJ100X750-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers robust thrust, pushing 7068 N at 0.9 MPa, making it suited for heavy-duty positioning tasks. The integrated magnet (-S) enables seamless position feedback using AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves.
This model features a 750 mm nominal stroke that can be dialed back by up to 75 mm, providing a usable travel window of 675 to 750 mm. This built-in adjuster acts purely as a mechanical stop to fine-tune the retract end-position during commissioning or product changeover without adding external stops. It is not a locking device; the cylinder relies on live air pressure to hold the load, so for fail-safe load holding, a SAIL or BSAI variant is required.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-75S Is Used
Machine Changeover
Dial in the retract position by up to 75 mm to accommodate different product lengths on a packaging line without physically swapping cylinders.
End-Stop Calibration
Fine-tune the 675-750 mm travel window during initial commissioning to perfectly align heavy tooling without machining external spacers.
Variable Positioning
Adjust the stroke end-point on the fly for sorting or diverting items of varying widths on a high-thrust conveyor system.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-75S the Right Cylinder?
Choose this 100 mm bore when substantial force is required, pushing 7068 N at 0.9 MPa. If a smaller footprint is acceptable, a 80 mm bore provides 4523 N at 0.9 MPa. Conversely, scaling up to a 125 mm bore yields 11045 N at 0.9 MPa. The 75 mm adjustment range here is ideal for machines needing variable end-stops on the fly, contrasting with a fixed-stroke SAI cylinder when no tuning is needed.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 750 mm stroke, 75 mm adjustment, PT tapered port thread, and the -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this features a long 750 mm stroke with a 25 mm diameter carbon steel rod, external guide rails are recommended to prevent excessive side-loading and rod deflection.
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 SAIJ100X750-75S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides a push force of 7068 N and a pull force of 3681 N. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster screw allows you to shorten the 750 mm nominal stroke by up to 75 mm, creating a usable travel window of 675 to 750 mm. This mechanical stop fine-tunes the end position but does not lock the load without live air pressure.
