About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-75S
The AirTAC SAIJ100X290-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 215 to 290 mm. Delivering 5497 N of push force at 0.7 MPa, it handles heavy actuation tasks with precision. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for direct compatibility with CMSE reed and DMSE electronic sensors.
A defining advantage of this SKU is the 75 mm adjustment range, which allows operators to fine-tune end positions during commissioning or product changeovers without physically swapping the cylinder or adding external stops. It uses a robust 25 mm carbon steel rod with an M20x1.5 thread, and the mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts only as a travel stop to set deceleration endpoints; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-75S Is Used
Machine Changeover
Dial in the exact 215 to 290 mm end-position during product size transitions without swapping out the physical actuator.
End-Stop Tuning
Use the 75 mm rear adjustment screw to precisely set deceleration endpoints at commissioning, avoiding the need for external mechanical stops.
Heavy Forming Press
Leverage the 5497 N push force at 0.7 MPa to actuate heavy stamping or forming stations while trimming the stroke to match die heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-75S the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial thrust—5497 N at 0.7 MPa—combined with variable end-stop positioning across a 215-290 mm window. If you need less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, whereas moving up to a 125 mm bore provides 8590 N. The integrated rear adjuster is ideal for machine setups requiring on-the-fly stroke trimming rather than installing a fixed-stroke SAI cylinder.
For a drop-in ISO 15552 replacement, match the 100 mm bore, 290 mm stroke, 75 mm adjustment code, PT tapered port threads, and the -S magnet option. Because the stroke is 290 mm, an external guide rail is recommended to prevent excessive side-loading on the 25 mm rod. If your system must hold a load vertically without continuous air pressure, use an SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the SAIJ adjuster.

- ✓ 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 SAIJ100X290-75S FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster allows you to shorten the nominal 290 mm stroke by up to 75 mm, creating a usable travel window of 215 to 290 mm. This screw acts as a mechanical stop for end-position tuning and does not lock or hold the load without live air pressure.
