About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-40S
The AirTAC SAIJ160X145-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust for heavy-duty automation. It yields 14074N of push force at 0.7 MPa and reaches a maximum of 2050 kgf at 1.0 MPa. The integrated -S magnet enables position detection via AirTAC CMSE reed or DMSE electronic sensors fitted into the dual-side barrel grooves.
This specific SKU features a 145 mm nominal stroke paired with a 40 mm adjustment range, creating a usable travel window of 105 to 145 mm. You can fine-tune the retract end-position at commissioning without adding external stops. It utilizes a PT tapered port, a 40 mm carbon steel rod with an M36x2 thread, and variable air cushions at both ends to manage kinetic energy.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-40S Is Used
Heavy Machinery Changeover
Dial in the 105-145 mm retract distance during product size changes without physically replacing the actuator or adding mechanical shims.
Press Positioning
Leverage the 14074N push force at 0.7 MPa to form or press heavy components, using the rear adjuster to set precise bottoming depth.
Sensor-Driven Assembly
Utilize the -S magnet with DMSE electronic sensors to confirm end-of-stroke positions while tweaking the 40 mm adjustment window during setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-40S the Right Cylinder?
Select this 160 mm bore actuator when an application requires substantial pull force (9425N at 0.5 MPa) that a 125 mm bore cannot provide, but without stepping up to the massive 3204 kgf capacity of a 200 mm cylinder. The adjustable 105-145 mm travel window is ideal for product changeovers on a line, allowing operators to dial in the exact retract distance rather than swapping out a fixed-stroke SAI cylinder. To replace an ISO 15552 cylinder, match the 160 mm bore, 145 mm stroke, PT port thread, and -S magnet requirement.
Because the stroke is 145 mm, the 40 mm carbon steel rod and M36x2 thread provide excellent rigidity against side loads, though external guiding remains best practice for heavy off-center loads. The rear screw acts purely as a travel stop for deceleration and positioning; it is not a lock. If the machine requires true load-holding without live air pressure, specify an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160X145-40S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 40 mm. This creates a usable travel window of 105 to 145 mm, letting you fine-tune the retract end-position during commissioning without swapping the cylinder.
At 0.5 MPa it provides 10053N of push force and 9425N of pull force. At 0.7 MPa the push force increases to 14074N, with a maximum push force of 18095N at 0.9 MPa.
