About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-20
The AirTAC SAIJ100X350-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 330 to 350 mm, letting you dial back the end position by up to 20 mm during commissioning. Belonging to the 100 mm bore class, it delivers a robust 7068 N push force at 0.9 MPa, making it highly capable for heavy machinery.
This model uses a G1/2 port and a 25 mm carbon steel rod with an M20x1.5 thread. The extruded aluminum barrel includes sensor grooves on both sides for standard CMSE and DMSE switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-20 Is Used
Machine Changeover
Fine-tune the 330-350 mm travel window during product size changes without physically swapping out the actuator.
Heavy Material Handling
Leverage the 7068 N push force at 0.9 MPa to move heavy pallets or metal components along the production line.
End-Position Trimming
Use the 20 mm rear stopper screw to precisely set the retract distance for delicate pressing or clamping tasks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-20 the Right Cylinder?
Select this 100 mm bore cylinder when a 50 mm bore falls short of the required thrust, as the 50 mm version only provides 1767 N push force at 0.9 MPa compared to this model's 7068 N. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the retract end-position without swapping the cylinder or adding external stops. To replace an ISO 15552 cylinder, match the 100 mm bore, 350 mm stroke, 20 mm adjustment, PT port thread, and mounting style.
Because the nominal stroke is 350 mm, the 25 mm rod needs external guide support to prevent excessive side-loading. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI 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 SAIJ100X350-20 FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore double-acting cylinder provides a push force of 7068 N and a pull force of 3681 N.
The rear stopper screw lets you shorten the 350 mm nominal stroke by up to 20 mm, creating a 330-350 mm adjustable travel window. The adjuster is a stop, not a lock, so it cannot hold the load without continuous air pressure.
