About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-10S
The AirTAC SAIJ160X55-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position without swapping hardware. Based on a 55 mm nominal stroke and a 10 mm adjustment screw, it provides a usable travel window of 45-55 mm for precise mechanical setup. This bore size generates a substantial 10053 N pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads ensure a robust pneumatic connection. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-10S Is Used
Heavy Press Tuning
Dial in the exact 45-55 mm retraction depth on heavy pressing or staking stations during initial commissioning without machining new stopper blocks.
Product Changeover
Quickly adjust the end-of-stroke position on a 160 mm bore assembly line when transitioning between product variants that require slightly different travel distances.
Heavy Load Positioning
Leverage the 10053 N pull force to shift heavy jigs into place while using the rear screw to perfectly square the load against a mechanical stop.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-10S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires high force combined with variable end-stop positioning; if you need less thrust, stepping down to a 125 mm bore yields 6136 N push at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring a dialed-in retraction point, whereas a fixed SAI cylinder is sufficient for static stop requirements. For load-holding without continuous air pressure, integrate an external rod lock or consider the SAIL or BSAI series, as the SAIJ adjuster is not a locking mechanism.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 55 mm stroke, 10 mm adjustment range, PT port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. The 40 mm rod and M36x2 thread provide high rigidity, but even with a robust rod, long unsupported strokes require external guide rails to prevent side-loading damage.

- ✓ 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 SAIJ160AX55-10S FAQ
At 0.5 MPa operating pressure, 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 adjuster screw allows you to shorten the 55 mm nominal stroke by up to 10 mm, creating a 45-55 mm usable travel window. This stopper only sets the end position and deceleration; it does not lock the load without live air pressure.
