Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-100
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-100
The AirTAC SAIJ200X150-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a massive 15708N thrust at 0.5MPa and uses a SUS420J2 stainless steel rod for superior corrosion resistance. The built-in adjuster allows you to trim the effective travel back by up to 100mm, creating a precise 50-150mm usable stroke window for exact end-position tuning.
This heavy-duty actuator operates at 30-500mm/s and features a G3/4 PT tapered port. Unlike fixed-stroke SAI cylinders, this model allows on-the-fly mechanical adjustments during commissioning or product changeovers. The rear screw acts purely as a travel stop and works alongside the standard adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-100 Is Used
Heavy Press Tuning
Dial in the exact 50-150mm compression distance during heavy-duty metal forming or pressing operations without swapping out the entire actuator.
Product Changeover
Quickly readjust the end-stop on a packaging line when switching to a different pallet or product size, minimizing machine downtime.
Assembly Calibration
Fine-tune the clamping end-position during initial commissioning of large automated assembly fixtures to ensure perfect component mating.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-100 the Right Cylinder?
Choose this 200mm bore cylinder when your application requires extreme force (up to 3204kgf at 1.0MPa) alongside variable end-stops. If you do not need to dynamically tune the stroke, a standard SAI200X150 provides the same ISO 15552 footprint and thrust. For lighter loads, stepping down to a 160mm bore yields 10053N push force at 0.5MPa, which may better suit mid-range machinery.
When replacing an ISO 15552 cylinder, match the 200mm bore, 150mm nominal stroke, 100mm adjustment range, G3/4 PT port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface. Because this is a plain SAIJ without a magnet, it cannot host CMSE or DMSE sensors. Remember that the rear adjuster is a stop, not a lock; if you need to hold a load without live air pressure, select an SAIL or BSAI cylinder instead. For any stroke exceeding 300mm, an external guide is recommended to prevent rod side-loading, though this 150mm travel remains well within safe bending limits.
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 SAIJ200AX150-100 FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa operating pressure, it delivers up to 3204kgf.
The rear adjusting screw allows you to mechanically shorten the 150mm nominal stroke by up to 100mm, resulting in a usable travel window of 50-150mm. This stopper only sets the end position and does not lock or hold the load without continuous air pressure.
