About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-100
The AirTAC SAIJ160X140-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the 140 mm nominal travel back by up to 100 mm. This creates a wide 40-140 mm usable window, allowing you to dial in the exact end position during commissioning without swapping out the unit. It delivers substantial thrust, generating 9425 N of pull force at 0.5 MPa and reaching 18095 N at 0.9 MPa.
Built with a SUS304 stainless steel rod and PT tapered port threads, this 160 mm bore actuator handles demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-100 Is Used
Product Changeover
Dial the retract stroke from 140 mm down to 40 mm instantly when switching to a shorter product variant on the line.
End-Stop Calibration
Fine-tune the final end position during machine setup without machining external stopper blocks or changing cylinders.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-100 the Right Cylinder?
Choose this 160 mm bore when a smaller 125 mm cylinder (providing 5734 N pull at 0.5 MPa) lacks the force needed for heavy positioning, but stepping up to a 200 mm bore is unnecessary. The 100 mm adjustment range is ideal for machinery requiring highly variable product sizes, letting you fine-tune the retract end-stop on the fly instead of relying on a fixed-stroke SAI cylinder. Because the stroke extends to 140 mm, ensure external guides are used to manage side loads and prevent rod binding.
For load-holding without continuous air pressure, note that this cylinder's adjuster is a travel stop, not a lock; you would need an external rod lock or a SAIL pneumatic lock cylinder for secure positioning. To match this ISO 15552 interchangeable cylinder, specify the 160 mm bore, 140 mm stroke, 100 mm adjustment, PT port thread, SUS304 rod, and no 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 SAIJ160 Adjustable Cylinder SAIJ160BX140-100 FAQ
The rear adjuster acts as a mechanical stopper that lets you shorten the 140 mm nominal stroke by up to 100 mm. This provides a usable travel window of 40 to 140 mm, which can be fine-tuned during commissioning. The adjuster only sets the travel end and does not lock the load without live air pressure.
At 0.9 MPa, the push force increases to 18095 N.
