Airtac SAIJ100 Adjustable Cylinder SAIJ100X325-10
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X325-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 325mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X325-10
The AirTAC SAIJ100X325-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stopper for precise stroke trimming. It provides a usable travel window of 315 to 325 mm, letting you dial back the nominal 325 mm stroke by up to 10 mm during machine setup. This bore generates 3927 N of push force at 0.5 MPa and features a durable carbon steel piston rod with an M20x1.5 male thread.
Because the adjustment mechanism acts directly on the retract end-position, you can fine-tune travel without swapping out the entire barrel or adding bulky external stops. The extruded aluminum profile includes dual sensor grooves for CMSE reed or DMSE solid-state switches, though a magnet (-S) must be specified to activate them. The rear adjuster serves strictly as a travel stop and deceleration point, meaning it will not hold the load safely without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X325-10 Is Used
Product Changeover
Quickly fine-tune the 315-325 mm travel window during line format changes without disassembling the cylinder or adding external shims.
Heavy Pressing
Leverage the 3927 N push force at 0.5 MPa for robust pressing operations, adjusting the final 10 mm of travel to hit exact material depths.
Machine Setup
Use the rear stopper to dial in exact retract positions during initial commissioning, compensating for mechanical tolerances on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X325-10 the Right Cylinder?
Selecting this 100 mm bore is ideal when your application requires heavy thrust—up to 7068 N at 0.9 MPa—exceeding the 2513 N push force of the smaller 80 mm bore at 0.5 MPa. An adjustable stroke is preferred over a fixed SAI cylinder when you need on-the-fly end-position tuning for product changeovers or to compensate for mechanical tolerance stack-up during commissioning.
For a drop-in ISO 15552 replacement, match the 100 mm bore, 325 mm stroke, 10 mm adjustment range, PT tapered port thread, and carbon steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR styles. Since the 325 mm stroke is relatively long, ensure your mounting configuration supports the rod against side-loading, or add an external guide to prevent premature wear. For applications requiring true load-holding without continuous air pressure, choose the SAIL lock or BSAI clamp-lock variants instead of relying on the rear stopper.
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 SAIJ100X325-10 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If you increase the operating pressure to 0.9 MPa, the push force reaches 7068 N.
The rear adjusting screw acts as a mechanical stopper on the retract end, allowing you to shorten the effective stroke from 325 mm down to a minimum of 315 mm. This provides a 10 mm tuning window for precise end-position setup without changing the cylinder.
