About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-100S
The AirTAC SAIJ100X300-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 200-300 mm usable travel window, letting you dial back the 300 mm nominal stroke by up to 100 mm during commissioning. Delivering 5497 N of push force at 0.7 MPa, it handles heavy actuation tasks without needing external stops.
This -S variant includes a magnet for position sensing, supporting AirTAC CMSE reed and DMSE solid-state switches in the dual-side sensor grooves. It uses a PT G1/2 port, a 25 mm carbon steel rod with an M20x1.5 thread, and adjustable air cushions at both ends. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-100S Is Used
Variable End-Stop Tuning
Dial in the exact 200 to 300 mm travel window during machine commissioning without swapping cylinders or adding external mechanical stops.
Product Changeover
Quickly adapt end positions on packaging lines processing different carton sizes by adjusting the rear stopper screw.
Heavy Pressing Operations
Leverage 5497 N of thrust at 0.7 MPa for pressing and forming tasks that require precise final position calibration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-100S the Right Cylinder?
Choose this 100 mm bore when 50 mm (1374 N at 0.5 MPa) is too weak or 125 mm (8590 N at 0.5 MPa) is excessive. The 100 mm adjuster is ideal for product changeovers requiring variable end stops. For strokes of 300 mm or more, the M20x1.5 rod needs an external guide to prevent side-load damage.
The rear screw acts as a travel stop, not a lock; it cannot hold loads without live air. For fail-safe holding, use SAIL or BSAI cylinders. To replace an ISO 15552 unit, match the 100 mm bore, 300 mm stroke, 100 mm adjust, PT G1/2 port, and -S magnet.
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 SAIJ100X300-100S FAQ
At 0.7 MPa operating pressure, it provides 5497 N of push force and 5497 N of pull force. Maximum thrust is 801 kgf at 1.0 MPa.
The rear adjuster screw trims the effective travel from the 300 mm nominal stroke down to a minimum of 200 mm. It functions as an end-position stop and does not lock the load without air pressure.
