About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-40S
The AirTAC SAIJ160X55-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down to a 15-55 mm window. Equipped with a SUS420J2 stainless steel rod and a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors for precise position feedback. Delivering 10053 N of pull force at 0.5 MPa, it handles heavy loads without needing external stops.
This model uses a PT tapered port thread and includes variable air cushions at both ends to decelerate the massive 14074 N push force at 0.7 MPa. The rear adjuster acts purely as a travel stop to fine-tune the end position during commissioning; it does not lock the load without live air pressure. For load-holding applications, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-40S Is Used
Precision Pressing
Dial in the exact 15-55 mm travel window during machine setup to ensure consistent pressing force without mechanical spacers.
Product Changeover
Quickly adjust the rear stopper to accommodate varying part sizes on an automated line, reducing downtime between runs.
Heavy Assembly
Leverage the 14074 N push force at 0.7 MPa to seat large components, using the rear screw to prevent overtravel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-40S the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high thrust—delivering 10053 N pull and 14074 N push at 0.7 MPa—within a compact 55 mm nominal stroke that requires exact end-position tuning. If you need less force, stepping down to a 125 mm bore yields 5734 N pull at 0.5 MPa. The 40 mm adjustment range is ideal for product changeovers, allowing you to dial in the stroke without swapping the cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 55 mm stroke, 40 mm adjustment, PT ports, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the nominal stroke is under 300 mm, side-load concerns are minimized, but an external guide is still recommended for heavy radial 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 SAIJ160AX55-40S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 55 mm nominal stroke by up to 40 mm, creating a usable travel window of 15 to 55 mm. It requires live air to move and does not lock the load in place.
