About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX15-10
The AirTAC SAIJ100X15-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 5 to 15 mm, allowing you to dial back the 15 mm nominal stroke by up to 10 mm during machine setup. It delivers robust thrust, offering 3927 N push force at 0.5 MPa and 7068 N at 0.9 MPa.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Mounting options utilize the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX15-10 Is Used
Precision End-Stop Tuning
Dial in the exact 5 to 15 mm travel window during commissioning to perfect a pressing or clamping operation without machining custom spacers.
Machine Changeover
Quickly adjust the rear stopper to accommodate slight variations in product size on a production line, reducing setup downtime.
Short-Stroke Forming
Leverage the 7068 N push force at 0.9 MPa for high-impact stamping or forming tasks within a compact 15 mm travel envelope.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX15-10 the Right Cylinder?
Choose this 100 mm bore when 50 mm (982 N push at 0.5 MPa) lacks force, but a 125 mm (6136 N) is oversized. The adjustable stroke is ideal for applications needing precise end-position tuning at commissioning without swapping cylinders or adding external stops. The rear adjuster acts as a travel stop to set deceleration, not a lock; a plain SAIJ does not hold loads without live air. For load-holding without pressure, consider SAIL, BSAI, or an external rod lock.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 15 mm stroke, 10 mm adjustment, G1/2 port, and mounting style. Because the stroke is short, side-loading is minimal, but always ensure the rod thread (M20x1.5) aligns with your clevis or fitting.
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 SAIJ100BX15-10 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. At 0.9 MPa, the push force increases to 7068 N. The maximum thrust is 801 kgf at 1.0 MPa.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 15 mm nominal stroke by up to 10 mm. This creates a usable travel window of 5 to 15 mm, enabling fine end-position tuning without changing the cylinder or adding external stops.
