About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-30S
The AirTAC SAIJ200X325-30-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It delivers 15708 N of push force at 0.5 MPa and features a rear adjusting screw that creates a 295-325 mm usable travel window from the 325 mm nominal stroke. This allows operators to dial in the retract distance during commissioning without adding external stops.
Built for durability, this variant incorporates a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and pairs with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports position monitoring via CMSE reed or DMSE electronic solid-state switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-30S Is Used
Heavy Press Tuning
Dial in the exact 295-325 mm end-stop during machine setup to accommodate varying material thicknesses in large-scale metal forming or pressing operations.
Product Changeovers
Rapidly adjust the retract position on automated packaging lines when switching box sizes, eliminating the downtime required to physically swap out the entire actuator.
Large Assembly Stops
Provide a highly rigid, finely tuned mechanical stop for heavy automotive or industrial component assembly, leveraging the 15708 N thrust capacity at 0.5 MPa.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-30S the Right Cylinder?
Choose this 200 mm bore when 125 mm bore cylinders (providing 6136 N push at 0.5 MPa) cannot meet your thrust requirements. The adjustable rear stopper is ideal for product changeovers on packaging lines, functioning purely as a travel limit and not a load-holding lock; for dead-load holding without live air, select an SAIL or BSAI cylinder. Because the 325 mm stroke is substantial, the 40 mm rod diameter and M36x2 thread provide rigidity, but an external guide is recommended to prevent excessive side-loading on the piston.
For ISO 15552 dimensional interchangeability, match the 200 mm bore, 325 mm stroke, 30 mm adjustment range, G3/4 PT ports, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on other series.
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 SAIJ200AX325-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel by up to 30 mm, creating a 295-325 mm usable stroke window. This stopper only sets the end position and does not hold the load without live air pressure.
