About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-20S
The AirTAC SAIJ160X145-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 145 mm stroke by up to 20 mm for a precise 125-145 mm usable travel window. The integrated magnet (-S) supports CMSE reed and DMSE electronic sensors for exact end-of-stroke detection.
This model features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. The extruded aluminum barrel includes sensor grooves on both sides, and the standard PT tapered port is G3/4. It uses variable air cushions at both ends to decelerate high moving masses smoothly across its 30-500 mm/s speed range.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
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 SAIJ160BX145-20S Is Used
Heavy Machinery Setup
Fine-tune the 125-145 mm retract position during heavy machinery commissioning to achieve perfect tooling alignment without machining external stoppers.
Product Size Changeover
Adapt automated lines quickly when product dimensions change by dialing in the stroke adjustment screw to accommodate new part sizes on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-20S the Right Cylinder?
The adjustable stroke is ideal for fine-tuning the retract end position during commissioning or product changeover without swapping the cylinder. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding without pneumatic pressure, consider an AirTAC SAIL locking cylinder or an external rod lock.
Because the 145 mm stroke exceeds 300 mm? No, but for any stroke over 300 mm you would need an external guide to prevent side-loading. This specific ISO 15552 interchangeable cylinder uses a G3/4 PT port, the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), and a SUS304 rod. If you do not need variable end-stops, a fixed-stroke SAI cylinder simplifies the setup.
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 SAIJ160BX145-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20 mm. This provides a usable travel window of 125-145 mm, allowing you to set the exact retract end-position without adding external stops.
