About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-20S
The AirTAC SAIJ100X750-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers a robust 5497N push force at 0.7 MPa, making it well-suited for heavy-duty positioning tasks. The integrated -S magnet enables precise end-of-stroke detection when paired with AirTAC CMSE reed or DMSE electronic sensors.
This specific SKU provides a 730-750mm usable travel window, allowing you to fine-tune the retract end-position by up to 20mm during commissioning without adding external stops. The extruded aluminum barrel features dual sensor grooves, and the carbon steel piston rod utilizes an M20x1.5 thread. It supports a standard operating speed of 30-800mm/s.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-20S Is Used
Product Size Changeovers
Dial in the 730-750mm retract end-stop on the fly when switching a packaging line between different large-format container sizes.
Long-Stroke Assembly Press
Leverage the 5497N push force at 0.7 MPa to seat heavy components, using the 20mm adjuster to dial in the exact final contact position.
Variable End-Stop Conveying
Act as a robust 100mm bore stopper arm on a conveyor, fine-tuning the physical blocking distance by up to 20mm during machine setup.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-20S the Right Cylinder?
Selecting this 100mm bore unit is ideal when an application demands high thrust over a long 750mm stroke but requires exact end-position tuning for varying product sizes. If you need slightly less force, stepping down to an 80mm bore yields 3518N at 0.7 MPa; stepping up to 125mm provides 8590N. Because the 750mm stroke is substantial, an external guide is strongly recommended to prevent excessive side-loading on the M20x1.5 rod.
The rear adjuster functions strictly as a travel stop, not a load-holding lock; the cylinder will not maintain its position without live air pressure. For true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. This SAIJ model uses a PT tapered port and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100X750-20S FAQ
At a 0.7 MPa operating pressure, this 100mm bore cylinder generates a push force of 5497N and a pull force of 3681N. It can achieve a maximum push force of 7068N at 0.9 MPa.
The rear adjuster allows you to shorten the effective stroke by up to 20mm, creating a 730-750mm usable travel window. This lets you fine-tune the end position at commissioning without swapping the cylinder.
