About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-20S
The AirTAC SAIJ100X200-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 200 mm nominal travel to a precise 180-200 mm window during commissioning. It delivers robust thrust, generating 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear stopper functions purely as a travel end-setter, not a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-20S Is Used
Machine Setup Changeover
Dial in the 180-200 mm travel window during product family changeovers to accommodate slight size variations without physically replacing the cylinder.
Heavy-Duty Positioning
Leverage the 7068 N push force at 0.9 MPa to move heavy pallets or fixtures, relying on the rear screw to fine-tune the final resting position.
End-Stop Calibration
Trim the retract position by up to 20 mm during initial commissioning to perfectly align tooling points without machining external stop blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-20S the Right Cylinder?
Select this 100 mm bore cylinder when an 80 mm bore (providing 2513 N push at 0.5 MPa) lacks the necessary force, but you want to avoid stepping up to a 125 mm size. The adjustable stroke is ideal for applications requiring fine end-position tuning without adding external stops or swapping out a fixed-stroke SAI cylinder. To match this ISO 15552 interchangeable unit, specify the 100 mm bore, 200 mm stroke, 20 mm adjustment, PT tapered ports, and the -S magnet.
Because the nominal stroke is 200 mm, side-load stress is moderate, but the 25 mm rod and M20x1.5 thread provide a rigid interface that handles lateral forces well. For any load-holding requirements without live air pressure, integrate an external pilot-operated check valve or select an AirTAC SAIL or BSAI cylinder, as the SAIJ adjuster is only a stop.
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 SAIJ100 Adjustable Cylinder SAIJ100BX200-20S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a stopper that allows you to shorten the effective travel from the 200 mm nominal stroke down to 180 mm. It sets the end position but does not lock the load without continuous air pressure.
