About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-100S
The AirTAC SAIJ200X150-100-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to trim the effective stroke. With a 150 mm nominal stroke and a 100 mm adjustment range, it provides a wide usable travel window of 50 to 150 mm for highly variable end-stop positioning. Built to deliver immense thrust, it outputs 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to a massive 3204 kgf at 1.0 MPa.
This model is equipped with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. Fluid is supplied via PT tapered ports sized at G3/4, and the extruded aluminum barrel incorporates sensor grooves on both sides. The rear adjuster functions strictly as a travel stop to set the end position, not as a lock, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-100S Is Used
Heavy-Duty Pressing
Adjust the 50-150 mm travel window to apply precise pressing force on varying heavy-gauge materials without changing tooling.
Product Size Changeover
Dial back the stroke up to 100 mm on packaging lines to accommodate different package lengths on the fly.
Variable End-Stop Setup
Set exact retraction end-positions during machine commissioning to prevent over-travel on large actuators.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-100S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires extreme force combined with variable end-stop positioning during machine setup or product changeover. If you need slightly less force, stepping down to the 160 mm bore yields 10053 N of push at 0.5 MPa, but the 200 mm bore is necessary for heavy-duty pressing. The 100 mm adjustment range allows you to fine-tune the travel window from 50 to 150 mm without swapping the cylinder or adding external stops, which is far more efficient than using a fixed-stroke SAI cylinder for varying product sizes.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 150 mm stroke, 100 mm adjustment, G3/4 PT ports, and the -S magnet requirement. Because the nominal stroke is 150 mm, side-load concerns are manageable, but the 40 mm rod diameter and M36x2 thread handle substantial side loads if they arise. Remember that for load-holding without live air pressure, you must look to the SAIL or BSAI series, as the SAIJ adjuster is only a stop. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX150-100S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 150 mm nominal stroke by up to 100 mm, creating a usable travel window of 50 to 150 mm. It only sets the end position and does not lock the load without live air pressure.
