Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-40S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 80mm 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 SAIJ160AX80-40S
The AirTAC SAIJ160X80-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 80mm travel to a precise usable window of 40-80mm without adding external stops. It delivers robust thrust, pushing 14074N at 0.7MPa and pulling 9425N, making it ideal for heavy-duty operations. The piston rod utilizes SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and the -S magnet option enables direct mounting of CMSE reed or DMSE solid-state sensors into the extruded aluminum barrel grooves.
This model features a PT tapered port and a 50mm air cushion at both ends to absorb kinetic energy. The rear adjuster acts purely as a travel stop to fine-tune end positions during commissioning; it is not a lock and will not hold a load without live air pressure. For applications requiring true position holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-40S Is Used
Heavy Press Tuning
Dial in the exact 40-80mm travel window during heavy press commissioning to accommodate varying material thicknesses without physically swapping cylinders.
Product Changeover
Quickly adjust the retract end-stop on packaging lines handling different package sizes, using the rear adjuster instead of repositioning mechanical hard stops.
Robotic End Effectors
Provides the high 14074N push force needed for large robotic grippers while allowing software teams to mechanically zero the stroke window during cell setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-40S the Right Cylinder?
Choose this 160mm bore when you need significantly more force than the 125mm bore (which provides 8590N push at 0.7MPa) but do not require the massive 21991N output of the 200mm class. The adjustable stroke is highly beneficial for machine setups where product sizes vary, letting operators fine-tune the retract end-position on the fly rather than swapping out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 160mm bore, 80mm nominal stroke, 40mm adjustment range, PT port thread, and the -S magnet requirement. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, explicitly omitting FB, CA, CB, and CR mounts. The 40mm rod thread (M36x2) handles high side loads well, though any long unsupported stroke still necessitates an external guide.
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 SAIJ160AX80-40S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. It can deliver a maximum push force of 18095N at 0.9 MPa.
The rear adjuster allows you to mechanically shorten the 80mm nominal stroke anywhere within a 40-80mm usable travel window. It functions as a physical travel stop for end-position tuning, not as a load-holding lock.
