About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-40S
The AirTAC SAIJ160X160-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. Equipped with a standard carbon steel rod and a -S magnet, it delivers substantial thrust, pushing 14074N at 0.7MPa and 18095N at 0.9MPa. The built-in magnet allows seamless integration with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves.
With a nominal 160mm stroke and a 40mm adjustment range, this model yields a usable travel window of 120-160mm. This built-in mechanical stopper lets you dial back the retract end-position during commissioning without adding external stops. The adjuster and the variable air cushions only manage end-of-travel deceleration, so they cannot hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-40S Is Used
Heavy Press Fine-Tuning
Dial in the exact 120-160mm travel window during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Rapidly adjust the retract end-stop on packaging lines when switching to a different product size, minimizing machine downtime.
Variable End-Stop Positioning
Set precise end positions for heavy-duty assembly jigs where the exact retraction point must be tweaked on-site to perfect the process.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-40S the Right Cylinder?
Select this 160mm bore when your application requires heavy thrust between the 10053N of a 125mm bore and the 15708N of a 200mm bore at 0.5MPa. The adjustable stroke is chosen over a fixed SAI cylinder when you need to fine-tune end positions during product changeovers. For exact ISO 15552 replacement matching, verify the 160mm stroke, 40mm adjustment, PT tapered port threads, and the -S magnet option. Note that the robust 40mm rod and M36x2 thread handle high side loads well, but any stroke over 300mm would still require an external guide.
If your system needs to hold a load statically without continuous air pressure, a plain SAIJ cylinder will not suffice since its rear adjuster acts only as a travel stop. For true fail-safe load holding, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
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 SAIJ160X160-40S FAQ
At 0.5MPa it provides 10053N of push force and 9425N of pull force. At the maximum operating pressure of 1.0MPa, it delivers up to 2050kgf of thrust.
The rear adjuster acts as a mechanical stop that lets you shorten the 160mm nominal stroke by up to 40mm, creating a usable travel window of 120-160mm. It only sets the end position and does not lock the load without live air pressure.
