About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-30S
The AirTAC SAIJ200X55-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. It features a 55mm nominal stroke that can be dialed back by up to 30mm, yielding a precise 25-55mm usable travel window for exact end-position tuning. This built-in adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure.
This specific configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and a magnetic piston (-S) for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid ports are PT tapered threads sized at G3/4.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-30S Is Used
Heavy Press Tuning
Dial in the exact 25-55mm end position during heavy press commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adjust the retract stop on a packaging line to accommodate different product sizes on the fly.
Robotic End Effectors
Utilize the 15708N force and SUS420J2 rod for robust, corrosion-resistant actuation in harsh industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-30S the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme force, offering 15708N push and 15080N pull at 0.5 MPa. If your setup requires less thrust, stepping down to a 160mm bore provides 10053N push force. The adjustable stroke is ideal for machine commissioning or product changeovers, allowing you to fine-tune the end stop without swapping cylinders or adding external stops. For load-holding without live air pressure, integrate an external rod lock or select the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 200mm bore, 55mm stroke, 30mm adjustment range, G3/4 PT ports, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Although the stroke is short, the 40mm rod diameter and M36x2 thread provide excellent side-load capacity, though any long unsupported travel still requires external guiding.
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 SAIJ200AX55-30S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can achieve a maximum push force of 28274N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 55mm nominal stroke by up to 30mm, creating a 25-55mm usable travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without air pressure.
