About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-40S
The AirTAC SAIJ100X260-40-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you trim the nominal 260 mm travel back by up to 40 mm. This yields a precise 220-260 mm usable end-position window at commissioning without bolting on external stops. The 100 mm bore delivers 3927 N of push force at 0.5 MPa, scaling up to 7068 N at 0.9 MPa.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and carries a built-in magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the fluid porting uses a PT tapered G1/2 thread.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-40S Is Used
Product Changeover
Dial in the 220-260 mm travel window during format changes without swapping the cylinder or repositioning hard stops.
End-Position Tuning
Fine-tune the retract end-position at commissioning to absorb mechanical tolerances and achieve exact seating.
Variable End Stops
Set custom retract distances on automated lines where multiple product sizes require different stroke lengths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-40S the Right Cylinder?
Choose this adjustable-stroke model when a fixed SAI cylinder cannot accommodate product changeovers or fine end-position tuning on a 260 mm stroke. The rear screw acts purely as a travel stop to set deceleration, not as a lock; a plain SAIJ does not hold loads without live air, so for fail-safe holding point to the SAIL or BSAI series. Because the 260 mm stroke is substantial, always support the load with an external guide to prevent side-loading damage to the M20x1.5 rod thread.
For a drop-in ISO 15552 replacement, match the 100 mm bore, 260 mm stroke, 40 mm adjustment, PT G1/2 port, and the -S magnet. The mounting hardware uses the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX260-40S 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 lets you shorten the 260 mm nominal stroke by up to 40 mm, creating a 220-260 mm usable travel window. It functions as a mechanical stop to set the end position, not as a load-holding lock.
