About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX25-10S
The AirTAC SAIJ200X25-10-S is a double-acting ISO 15552 profile cylinder delivering massive thrust, with 15708N push and 15080N pull at 0.5 MPa. It features a rear stroke adjuster that creates a 15-25mm usable travel window from the 25mm nominal stroke, allowing exact end-position tuning without external stops. The extruded aluminum barrel includes sensor grooves on both sides for mounting position switches.
Equipped with a SUS420J2 stainless steel rod (option A) and PT tapered port threads, this 200mm bore unit operates at 30-500mm/s. It supports AirTAC CMSE reed and DMSE electronic sensors via the integrated -S magnet. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX25-10S Is Used
Heavy Press Tuning
Dial in the exact 15-25mm travel window during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Short-Stroke End Stop
Set a precise retract end-position for high-force clamping tasks, using the rear stopper to make 10mm setup adjustments on the fly.
Product Changeover
Quickly adjust the effective stroke on automated heavy machinery lines when changing product sizes, avoiding the need to bolt on external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX25-10S the Right Cylinder?
Choose this 200mm bore when an application requires extreme force but only a very short, finely adjustable travel range. If you need less thrust, stepping down to a 160mm bore yields 10053N push at 0.5MPa. The rear adjuster screw acts purely as a mechanical stop to trim the stroke; it does not hold the load without live air pressure. For true load-holding, select an SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
As a dimensionally interchangeable ISO 15552 cylinder, replacement requires matching the 200mm bore, 25mm stroke, 10mm adjustment, G3/4 port, and -S magnet. Because the stroke is under 300mm, side-load risks are minimal, but the 40mm rod and M36x2 thread handle high stress well. For fixed end-positions without the 15-25mm tuning window, use a standard SAI cylinder.
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 SAIJ200AX25-10S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the 25mm nominal stroke by up to 10mm, creating a 15-25mm usable travel window. The adjuster functions as a mechanical stop and does not lock or hold the load without continuous air pressure.
