About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-100S
The AirTAC SAIJ200X325-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 15708N of push force at 0.5MPa and provides a usable travel window of 225 to 325mm, letting you dial back the nominal stroke by up to 100mm during commissioning.
This unit features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel carries sensor grooves on both sides, and the PT tapered G3/4 porting ensures high flow capacity for heavy-duty actuation.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-100S Is Used
Heavy Press Tuning
Fine-tune the 225-325mm travel window during setup to achieve precise pressing forces on large industrial assemblies without adding external stopper blocks.
Product Changeover
Quickly adjust the end-stop position on a conveyor diverter when handling different pallet sizes, using the 100mm rear screw to adapt the stroke on the fly.
Variable Positioning
Set exact retraction depths for heavy material handling jigs, leveraging the 15708N push force at 0.5MPa to move substantial loads safely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-100S the Right Cylinder?
Choose this 200mm bore if your application requires massive thrust—stepping down to a 160mm bore drops the 0.5MPa push force to 10053N. The 100mm adjustment range is ideal for product changeovers on large packaging lines, allowing variable end-stops without swapping the cylinder. Because the 325mm stroke is substantial, always use an external guide to prevent side-loading damage to the M36x2 rod thread.
For dimensionally interchangeable ISO 15552 replacements, match the 200mm bore, 325mm stroke, 100mm adjuster, PT G3/4 port, and -S magnet. Note that the rear adjuster is a travel stop, not a lock; a plain SAIJ cannot hold a load without live air. For fail-safe load holding, select the SAIL or BSAI series instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200AX325-100S FAQ
The rear adjuster acts as a mechanical stop that shortens the effective travel. For this model, you can trim the 325mm stroke back by up to 100mm, giving a usable travel window of 225 to 325mm. It only sets the end position; it does not lock the load without live air pressure.
At 0.5MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It operates at speeds between 30 and 500mm/s.
