About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-10
The AirTAC SAIJ160X140-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 10053N push force at 0.5MPa and uses a PT tapered G3/4 port. The integrated adjustment screw allows you to trim the nominal 140mm stroke back by up to 10mm, creating a precise 130-140mm usable travel window for exact end-position tuning.
This extruded aluminum barrel design includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches if you add a magnet later. The carbon steel rod and M36x2 thread handle heavy loads, while the 50mm air cushions at both ends decelerate the moving mass. The rear adjuster acts strictly as a travel stop, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-10 Is Used
Press Fit Tuning
Dial in the exact 130-140mm insertion depth for heavy press operations during initial setup or when changing tooling.
Product Changeover
Quickly adjust the end-stop to accommodate slightly different product lengths on the line without mechanical rebuilds.
Heavy Positioning
Move heavy jigs into place using 10053N of thrust, relying on the 50mm air cushions to soften the end of travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-10 the Right Cylinder?
Choose this 160mm bore when a 100mm bore (offering 3927N push at 0.5MPa) is insufficient, but a 200mm bore (15708N at 0.5MPa) is physically oversized. The 10mm adjustment range is ideal for fine-tuning the retract position during machine commissioning or product changeover without swapping cylinders or adding external stops. For load-holding without continuous air pressure, select the SAIL or BSAI series instead, as this adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 160mm bore, 140mm stroke, 10mm adjustment, PT G3/4 port, and carbon steel rod. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Because the 140mm stroke is relatively short for this large bore, side-load risks are minimal, but external guides remain recommended for heavy lateral masses.
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 SAIJ160X140-10 FAQ
At 0.5MPa operating pressure, this 160mm bore cylinder provides a push force of 10053N and a pull force of 9425N. It can deliver up to 2050 kgf at 1.0MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm from the 140mm nominal length, giving a 130-140mm travel window. It acts as a mechanical stop and does not lock the load without air pressure.
