About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-100S
The AirTAC SAIJ200X260-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 160 to 260 mm. It integrates a SUS420J2 stainless steel rod and a PT tapered port, tailored for heavy-duty positioning. Generating 15708 N of push force at 0.5 MPa, it is built for substantial loads.
This unit includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the extruded aluminum barrel grooves. The rear adjustment screw acts purely as a mechanical stop to fine-tune the end position at commissioning without swapping the cylinder; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-100S Is Used
Heavy Press Tuning
Dial in the exact 160-260 mm end-position during heavy press commissioning without physically swapping out the large 200 mm bore cylinder.
Product Size Changeover
Adapt quickly to varying product sizes on a packaging line by adjusting the rear stopper screw up to 100 mm to meet new travel requirements.
Variable End-Stop Setup
Establish a precise variable end-stop for large actuation tasks, relying on the 40 mm rod to handle significant side loads during travel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-100S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires up to 15708 N of thrust at 0.5 MPa, stepping up from a 160 mm bore that offers 10053 N. You would opt for this adjustable-stroke SAIJ over a fixed SAI when a machine changeover demands a variable end-stop within a 160-260 mm window, avoiding the need to bolt on external stops. To replace an ISO 15552 cylinder, match the 200 mm bore, 260 mm stroke, 100 mm adjustment, PT port, and -S magnet, utilizing the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.
Because the 260 mm stroke exceeds 300 mm in larger frames, note that long unsupported strokes still require an external guide to manage side-load, despite the robust 40 mm rod and M36x2 thread. For load-holding without live pressure, the adjuster is not a lock; consider an SAIL or BSAI cylinder instead.
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 SAIJ200 Adjustable Cylinder SAIJ200AX260-100S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. It can reach a maximum push force of 21991 N at 0.7 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 260 mm down to 160 mm, creating a 100 mm usable adjustment window. This mechanical stop fine-tunes the end position but does not lock the load without continuous air pressure.
