About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-100S
The AirTAC SAIJ100X275-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 100 mm bore and a 275 mm nominal stroke, yielding a usable travel window of 175-275 mm. This wide adjustment range allows precise end-position tuning during commissioning without swapping hardware. It delivers 3927 N of push force at 0.5 MPa and includes a -S magnet for position sensing.
This model uses a carbon steel piston rod with an M20x1.5 thread, paired with a G1/2 port. The extruded aluminum barrel incorporates sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts strictly as a travel stop for deceleration, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-100S Is Used
Product Changeover
Dial in the 175-275 mm travel window on the fly to accommodate different package sizes without changing the cylinder.
End-Stop Calibration
Fine-tune the retract end position during machine setup to achieve precise mechanical alignment.
Variable Forming
Adjust the rear stopper to set different pressing depths for multi-stage assembly operations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-100S the Right Cylinder?
Selecting this 100 mm bore cylinder makes sense when your application requires the 3927 N push force at 0.5 MPa (or 5497 N at 0.7 MPa) and a highly variable end-stop. The 100 mm adjustment window is ideal for product-size changeovers on a line. If you need less force, stepping down to an 80 mm bore provides 2513 N at 0.5 MPa. Because the 275 mm stroke exceeds 300 mm only marginally, standard side-load rules still apply: ensure external guiding for long unsupported travels.
This SKU is dimensionally interchangeable per ISO 15552. To match this exact configuration, specify: 100 mm bore, 275 mm stroke, 100 mm adjustment, PT tapered port thread, carbon steel rod, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB/CA/CB/CR). For load-holding without live air pressure, use an external rod lock or select the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ100X275-100S FAQ
The rear adjuster acts as a mechanical stop, allowing you to trim the effective travel anywhere within a 175 to 275 mm window. It sets the end position but does not lock the load without live air.
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
