About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-30S
The AirTAC SAIJ160X170-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 140 to 170 mm. Delivering substantial thrust, it generates 14074 N of push force and 9425 N of pull force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, and because this variant includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.
This heavy-duty bore utilizes a 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage kinetic energy. The rear adjuster functions strictly as a mechanical stop to dial in the end position during commissioning; it is not a locking device and will not hold a load without continuous live air pressure. For load-holding requirements, consider an external rod lock or the related SAIL pneumatic lock series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-30S Is Used
Press Stroke Tuning
Dial in the exact 140-170 mm end position during machine commissioning to accommodate varying material thicknesses without mechanical rebuilds.
Product Changeover
Quickly adjust the retract stop on packaging lines when switching to different container sizes, leveraging the 30 mm trim range for rapid setup.
Heavy Assembly Clamping
Utilize the 14074 N push force at 0.7 MPa to secure heavy components, relying on the 40 mm rod to withstand demanding industrial loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-30S the Right Cylinder?
Choose this 160 mm bore when an application demands higher force than a 125 mm cylinder (which provides 8590 N push at 0.7 MPa) but does not require the massive output of a 200 mm profile. The adjustable 140-170 mm window is invaluable for product changeovers, allowing operators to fine-tune the retract distance without swapping cylinders or adding external stops. If position holding is required without live air, a plain SAIJ is insufficient—look to the BSAI clamp-lock or SAIL locking variants instead.
To achieve a true ISO 15552 dimensional replacement, match the 160 mm bore, 170 mm nominal stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet option. Mounting choices for this series are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 170 mm stroke is relatively short for this large bore, side-load risks are minimal, but the heavy 40 mm rod still necessitates robust external guiding for any off-center loads.
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 SAIJ160X170-30S FAQ
The rear adjuster acts as a mechanical stopper that allows you to shorten the effective stroke by up to 30 mm, creating a usable travel window of 140 to 170 mm. It only sets the end position and does not lock the load without live air pressure.
At an operating pressure of 0.7 MPa, the SAIJ160X170-30-S generates a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
