About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-100S
The AirTAC SAIJ100X270-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 170-270 mm usable travel window, allowing you to dial back the nominal 270 mm stroke by up to 100 mm during commissioning. Delivering 7068N of push force at 0.9 MPa, it handles heavy loads with precision.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a piston magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-100S Is Used
Machine Changeover
Quickly adapt end-stop positions on packaging lines when switching between different carton sizes without replacing the cylinder.
Precision Positioning
Dial in the exact 170-270 mm travel distance required for delicate pressing or locating tasks during initial machine setup.
Heavy Load Handling
Leverage the 7068N push force to move substantial jigs or fixtures while retaining the ability to trim the stroke for safety.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-100S the Right Cylinder?
Choose this 100 mm bore cylinder when you need 7068N of thrust at 0.9 MPa and require flexible end-position tuning. If your application demands less force, the 80 mm bore provides 4523N at the same pressure. The 100 mm adjustment window is ideal for product changeovers, letting you fine-tune travel without swapping hardware. Note that the rear adjuster acts as a travel stop, not a lock; for load-holding without live air, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 270 mm stroke, 100 mm adjust, PT tapered ports, and the -S magnet option. For a 270 mm stroke, ensure external guides support the load to prevent rod side-loading.
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 SAIJ100BX270-100S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides a push force of 7068N and a pull force of 3681N. At 0.5 MPa, the push force is 3927N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 270 mm down to as little as 170 mm. It fine-tunes the retract end position but does not lock the load without live air pressure.
