About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-100
The AirTAC SAIJ100X350-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 3927N push force at 0.5MPa, making it ideal for heavy-duty positioning. By turning the integrated rear stopper screw, you can fine-tune the effective travel window anywhere between 250 and 350mm without adding external stops.
This 100mm bore unit uses a G1/2 port and a 25mm carbon steel piston rod to handle significant side loads. It supports CMSE and DMSE sensors if a magnet is added later, and relies on a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB and CA options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-100 Is Used
Press Tonnage Calibration
Dial in the exact 250-350mm stroke window during press setup to accommodate varying material thicknesses without swapping out the entire cylinder assembly.
Package Diverting
Adjust the retract stopper on the fly to handle different carton sizes on a packaging line, ensuring precise diverting without repositioning hard stops.
Heavy Fixture Clamping
Leverage the 3927N push force at 0.5MPa to secure heavy weldments, using the 100mm adjustment range to compensate for fixture wear or part tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-100 the Right Cylinder?
Select this 100mm bore when your application requires high thrust (up to 3927N at 0.5MPa or 7068N at 0.9MPa) and a 250-350mm travel window. If your force requirements are lower, a 80mm bore provides 2513N at 0.5MPa, while stepping up to a 125mm bore yields 6136N. The 100mm adjuster is perfect for product-size changeovers, letting you dial in the exact retract position at commissioning rather than machining custom spacers.
Because the nominal stroke is 350mm, an external guide rail is recommended to prevent rod sag and binding over the extended travel. The rear adjuster acts only as a travel stop for end-position tuning; it does not lock or hold the load without live air pressure. For true fail-safe load holding, pair this cylinder with an external pilot-operated check valve or select the BSAI clamp-lock series.
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 SAIJ100X350-100 FAQ
At a 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9MPa, the push force increases to 7068N.
The rear stopper screw lets you mechanically shorten the effective stroke by up to 100mm, creating a usable travel window of 250-350mm. This allows precise end-position tuning at commissioning without replacing the cylinder.
