About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX25-10S
The AirTAC SAIJ100X25-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 15-25 mm usable travel window, allowing you to dial back the 25 mm nominal stroke by up to 10 mm during commissioning. In the 100 mm bore class, it delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered ports ensure a tight, standard pneumatic connection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX25-10S Is Used
Machine Setup
Dial in the exact 15-25 mm travel window during initial machine commissioning to perfect end-position stops.
Product Changeover
Quickly adjust the retract end-stop by up to 10 mm on the rear screw when switching product sizes on the line.
Fine Positioning
Achieve precise end-position tuning without the need to remove the cylinder or bolt on external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX25-10S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when you need precise end-position tuning without swapping cylinders or adding external stops. If your application requires less force, stepping down to the 80 mm bore yields 2513 N of push at 0.5 MPa. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, use an external rod lock or consider the SAIL or BSAI series.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, omitting FB, CA, CB, and CR. Because the 25 mm stroke is well below the 300 mm threshold, side-load stress is minimal, though the robust 25 mm rod and M20x1.5 thread handle standard operational loads effectively.
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 SAIJ100BX25-10S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to trim the 25 mm nominal stroke back by up to 10 mm, creating a 15-25 mm usable travel window. It acts as a mechanical stop and does not lock the load without live air pressure.
