About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-40S
The AirTAC SAIJ100X220-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and a PT tapered port thread. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
With a 220mm nominal stroke and a 40mm adjustment range, this SKU provides a usable travel window of 180-220mm. This allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-40S Is Used
Product Changeovers
Dial in the 180-220mm travel window during format changes on packaging lines, using the rear screw to set new end positions without replacing hardware.
End-Position Trimming
Fine-tune the retract stroke during machine commissioning to prevent mechanical interference, relying on the 40mm adjustment range for exact positioning.
High-Force Clamping
Secure heavy workpieces using the 3927N push force at 0.5 MPa, verifying position via the integrated magnet and DMSE solid-state sensors.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-40S the Right Cylinder?
Choose this 100mm bore when you need higher thrust than the 80mm version (2513N push at 0.5 MPa) but want to avoid the bulk of a 125mm body. The adjustable 180-220mm window is ideal for product changeovers on a line, letting you dial in the exact end-stop mechanically. For any stroke near or over 300mm you would normally add an external guide, but at 220mm the 25mm rod and M20x1.5 thread handle standard side loads well.
Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold its load without live air. If you need true load-holding without pressure, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder exactly, specify the 100mm bore, 220mm stroke, 40mm adjustment, PT ports, SUS304 rod, and the -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 SAIJ100BX220-40S FAQ
At 0.5 MPa it provides 3927N of push force and 3681N of pull force. If you increase pressure to 0.7 MPa, the push force rises to 5497N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 220mm nominal stroke down to 180mm. It sets the end position but does not lock the load without live air pressure.
