About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-20S
The AirTAC SAIJ200X30-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust with 15708N push and 15080N pull at 0.5 MPa. Its 30mm nominal stroke can be dialed back by up to 20mm, creating a highly precise 10-30mm usable travel window for exact end-position tuning. This makes it exceptionally effective for applications requiring short, high-force movements that must be dialed in during commissioning.
This configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid ports are PT tapered G3/4 threads. It operates at speeds of 30-500 mm/s and utilizes a 50mm cushion at both ends to manage the significant kinetic energy of its 40mm diameter rod.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-20S Is Used
Heavy-Duty Pressing
Delivers up to 28274N of push force at 0.9 MPa for short-stroke pressing, with the 10-30mm window allowing precise depth control during machine setup.
Product Changeover
Quickly adjust the end-stop by up to 20mm to accommodate varying product sizes on the line without bolting on external stops or changing the cylinder.
Industrial Clamping
Provides massive clamping force in automated cells, using the SUS420J2 stainless rod to resist corrosion in harsh manufacturing environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-20S the Right Cylinder?
Choose this 200mm bore cylinder when your application demands extreme force that smaller bores cannot provide; stepping down to a 160mm bore would reduce your 0.5 MPa push force from 15708N to 10053N. The adjustable stroke is ideal for variable end-stops or product-size changeovers, allowing you to fine-tune the travel distance without swapping the cylinder or adding external stops. For any stroke at or above 300mm, an external guide is recommended to prevent rod side-loading, though this 30mm short-stroke model inherently minimizes such deflection.
When specifying a replacement, ensure you match the 200mm bore, 30mm stroke, 20mm adjustment range, PT G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold a load without live air. For true load-holding, consider an external rod lock or the AirTAC SAIL/BSAI series.

- ✓ 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 SAIJ200AX30-20S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.9 MPa, the push force increases to 28274N.
The rear adjuster screw allows you to trim the 30mm nominal stroke back by up to 20mm, providing a usable travel window of 10-30mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
