About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-40S
The AirTAC SAIJ200X210-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, generating 15708N of push force and 15080N of pull force at 0.5 MPa. By integrating an external adjusting stopper, this 210 mm nominal stroke unit provides a usable travel window of 170-210 mm, allowing precise end-position tuning without swapping out the entire cylinder.
Built for demanding environments, this variant features a SUS420J2 stainless steel rod (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 incorporates sensor grooves on both sides, and the G3/4 port handles high airflow to support the 30-500 mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-40S Is Used
Heavy Pressing Operations
Dials in the exact 170-210 mm pressing depth during machine setup, preventing over-travel on high-force assemblies requiring up to 15708N.
Product Changeover
Quickly adjusts the retract end-stop for varying product sizes on a line without bolting on external stops or changing the cylinder.
Large Clamp Actuation
Provides massive clamping force with a variable end-position window, accommodating different material thicknesses in heavy industrial fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-40S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires extreme force alongside variable end-stops, such as pressing or heavy clamping tasks that need on-the-fly calibration. If the full 210 mm stroke is excessive, stepping down to a 160 mm bore yields 10053N of push force at 0.5 MPa, but the SAIJ200X210-40-S remains unmatched for loads requiring up to 3204 kgf at 1.0 MPa. The adjustable rear screw is strictly a travel stop for fine-tuning the retraction point, not a locking device; it cannot hold a load without continuous live air pressure.
For a true ISO 15552 replacement match, verify the 200 mm bore, 210 mm stroke, 40 mm adjustment range, PT tapered port threads, and the -S magnet. Because the 210 mm stroke is relatively short for this massive bore, side-load concerns are minimal, but external guides are still recommended if the load is heavy or off-center. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR.
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 SAIJ200AX210-40S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum operating pressure of 1.0 MPa, it delivers a peak push force of 3204 kgf.
The rear adjusting screw acts as a mechanical stopper that trims the effective stroke. For this 210 mm nominal stroke cylinder, you can fine-tune the usable travel anywhere within a 170-210 mm window during commissioning without replacing the cylinder.
