Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-100
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 120mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-100
The AirTAC SAIJ160X120-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty motion. Using its 100 mm adjustment range, you can dial the effective travel back from a 120 mm nominal stroke down to a 20 mm minimum, creating a highly versatile 20-120 mm usable window. This allows precise end-position tuning at commissioning without swapping out the physical barrel. Built with a carbon steel piston rod and a PT tapered port thread, it handles substantial loads while maintaining standard ISO 15552 mounting interchangeability.
The defining feature of this SAIJ variant is the external rear stopper, which acts purely as a travel-limiting screw and deceleration boundary, not a load-holding lock. Without continuous live air pressure, this cylinder cannot hold its position, so you must integrate an external rod lock or choose an AirTAC BSAI clamp-lock cylinder if static load holding is required. The extruded aluminum barrel features dual-side sensor grooves, ready for CMSE reed and DMSE electronic switches if a magnet is specified later.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-100 Is Used
Heavy Press Tonnage
Delivers up to 18095 N of pulling force at 0.9 MPa for driving heavy stamping or forming presses.
Variable End-Stop Tuning
The 100 mm rear adjuster allows operators to dial in the retract position from 20 to 120 mm during product changeovers.
Assembly Machine Setup
Perfect for large assembly lines where the rear screw fine-tunes the end position at commissioning without adding external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-100 the Right Cylinder?
Select this 160 mm bore when your application demands extreme force, generating 14074 N of push and 9425 N of pull at 0.7 MPa. If your setup only requires moderate thrust, stepping down to a 100 mm bore yields 5497 N push at 0.7 MPa, which may be more cost-effective and lighter. The 100 mm adjustment range on this model is ideal for machines processing multiple product sizes, allowing you to fine-tune the retract end-stop on the fly rather than machining custom external stops.
For a true ISO 15552 replacement, match the 160 mm bore, 120 mm stroke, 100 mm adjuster, PT port thread, and your required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series. Because the nominal stroke of 120 mm is relatively short for this massive bore, side-load risks are manageable, but long unsupported strokes over 300 mm would still require an external guide.

- ✓ 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 SAIJ160X120-100 FAQ
It delivers a maximum push force of 18095 N at 0.9 MPa. The 120 mm nominal stroke combined with the 100 mm adjustment code creates a usable travel window of 20 to 120 mm, allowing the retract end-position to be shortened as needed.
No, the rear adjuster functions only as a travel stop and deceleration boundary, not a lock. The double-acting cylinder cannot hold a load without live air; for fail-safe load holding, use an AirTAC BSAI clamp-lock cylinder or an external rod lock.
