About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-30S
The AirTAC SAIJ200X300-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suited for heavy-duty press applications. The integrated -30 mm adjustment mechanism allows you to fine-tune the usable travel window down to 270 mm without physically swapping the barrel.
This variant includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic switches housed in the dual-side sensor grooves. It features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered ports sized at G3/4. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while omitting the FB, CA, CB, and CR brackets found on other series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-30S Is Used
Heavy Press Tuning
Dial in the exact 270-300 mm stroke during heavy-duty press setup to accommodate different material thicknesses without changing the cylinder.
Changeover Adjustment
Fine-tune the retract end position on automated assembly lines when switching between product variants, using the rear stopper for precise variable end stops.
Large Mold Handling
Position large industrial molds accurately, relying on the 28274N of thrust at 0.9 MPa and the SUS420J2 stainless rod for robust, corrosion-resistant operation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-30S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force that smaller bores cannot provide, such as stepping up from a 160 mm bore that yields 18095N of push force at 0.9 MPa. The adjustable stroke is ideal for product changeovers, letting you dial in the exact 270-300 mm end position during commissioning rather than machining external stops. Because the 300 mm stroke is substantial, the 40 mm rod diameter handles high side loads, but you should still utilize an external guide rail to prevent binding over long travels. Remember that the rear adjuster acts only as a travel stop; it will not hold the load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ200AX300-30S FAQ
At 0.9 MPa, this 200 mm bore cylinder provides 28274N of push force and 22680N of pull force. It reaches a maximum of 3204 kgf at 1.0 MPa.
The nominal stroke is 300 mm, but the rear adjuster allows you to shorten the effective travel by up to 30 mm, creating a usable window of 270-300 mm for fine-tuning the end position.
