About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-40S
The AirTAC SAIJ160X145-40-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 40 mm. This creates a precise 105-145 mm usable travel window for fine end-position tuning during commissioning without swapping the cylinder or adding external stops. It delivers substantial thrust, providing 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the included magnet supports AirTAC CMSE reed and DMSE electronic switches. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets.

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 SAIJ160BX145-40S Is Used
Heavy Press Changeover
Dial in the 105-145 mm travel window during product-size changeovers on a heavy press line without physically swapping out the cylinder.
Machine Setup Tuning
Fine-tune the retract end-position at commissioning using the rear stopper to perfectly seat large components without adding external stops.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for high-force clamping in washdown or corrosive manufacturing environments while maintaining ISO 15552 mounts.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-40S the Right Cylinder?
Select this 160 mm bore when a 125 mm bore (offering 5734 N pull at 0.5 MPa) cannot provide enough force, but you want to avoid stepping up to a massive 200 mm unit. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers. To match an ISO 15552 replacement, verify the 160 mm bore, 145 mm stroke, 40 mm adjustment, PT ports, SUS304 rod, and the -S magnet.
Remember that the rear adjuster acts as a travel stop, not a lock; it cannot hold a load without live air pressure. For true load-holding without continuous air, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. Since the 145 mm stroke is well under the 300 mm threshold, side-load concerns are minimal, but the robust 40 mm rod and M36x2 thread handle high stresses effectively.
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 SAIJ160BX145-40S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 40 mm, creating a usable travel window of 105-145 mm. This allows fine end-position tuning during commissioning without replacing the cylinder.
At 0.9 MPa, the push force increases to 18095 N. Note that the rear adjuster only sets the travel end and does not lock or hold the load without live air pressure.
