About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-30S
The AirTAC SAIJ100X220-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers a robust 7068N of push force at 0.9 MPa, utilizing a G1/2 port and a 25mm piston rod. The integrated -S magnet enables position sensing across both barrel grooves using AirTAC CMSE reed or DMSE solid-state switches.
This specific SKU provides a 190-220mm usable travel window, letting you dial back the nominal 220mm stroke by up to 30mm during commissioning without adding external stops. The standard extruded aluminum barrel design omits tie-rods, and the SUS304 stainless steel rod material (code B) supplies superior corrosion resistance for demanding environments.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-30S Is Used
Machine Changeover
Dial in the 190-220mm travel window during product size transitions to set new physical end positions without swapping the cylinder.
End-Position Tuning
Fine-tune the retract stop at commissioning to perfect a pressing or clamping operation, avoiding the need for external stopper blocks.
Variable Forming Stops
Adjust the stroke mechanically on the production line to accommodate different material lengths or forming depths on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-30S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (yielding 4523N push at 0.9 MPa) lacks sufficient thrust, but a 125mm bore (8590N at 0.7 MPa) would be excessive. The adjustable end-stop is ideal for machine setups requiring precise physical positioning without re-engineering the pneumatic layout. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 220mm stroke exceeds 300mm? No, but for any stroke over 300mm, external guidance is required to manage side loads. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for true pneumatic locking, select the SAIL or BSAI series instead. To match this ISO 15552 replacement, verify the 100mm bore, 220mm stroke, 30mm adjustment, PT tapered ports, and the -S magnet requirement.
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 SAIJ100BX220-30S FAQ
At 0.9 MPa, this 100mm bore cylinder generates 7068N of push force and 3681N of pull force. At 0.5 MPa, it provides 3927N push and 3681N pull.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 220mm down to 190mm. It sets the end position but does not lock the load without live air pressure.
