About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-100
The AirTAC SAIJ200X210-100 is a double-acting ISO 15552 profile cylinder engineered for high-thrust applications, delivering 15708N of push force at 0.5 MPa. It features a robust 40mm piston rod with an SUS420J2 stainless steel material (code A) for enhanced durability against moisture and corrosion. The PT tapered port threads ensure a reliable, leak-free pneumatic connection at the G3/4 fitting.
Equipped with a 100mm rear stroke adjuster, this model transforms a fixed 210mm stroke into a highly versatile 110-210mm usable travel window. This built-in stopper allows operators to dial in the exact retract end-position during commissioning or product changeovers without swapping out the entire cylinder. The extruded aluminum barrel features dual sensor grooves, allowing for flexible mounting of CMSE or DMSE switches if position feedback is later required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-100 Is Used
Heavy Press Tuning
Fine-tune the 110-210mm travel window on high-tonnage pressing operations to accommodate different material thicknesses without mechanical retooling.
Product Changeover
Rapidly adjust the retract end-position on automated lines handling varying product sizes, leveraging the 100mm adjustment range for quick setup.
Large Assembly Alignment
Utilize the 15708N thrust to seat heavy components precisely, dialing back the stroke in 1mm increments to perfect the final alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-100 the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application demands extreme force, stepping up significantly from the 125mm bore which provides 6136N push force at 0.5 MPa. The 100mm adjustment range is particularly valuable in heavy machinery where precise end-stop tuning is necessary to accommodate varying product sizes on a single line. Because the stroke is 210mm, which is relatively short for this massive bore, side-load risks are minimized, but external guides are still recommended if the load is offset.
When specifying a replacement, ensure you match the 200mm bore, 210mm stroke, 100mm adjustment, PT port threads, and SUS420J2 rod material. Keep in mind the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Crucially, the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, 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 SAIJ200AX210-100 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9 MPa.
The rear adjuster acts as a mechanical stopper that allows you to shorten the effective stroke from its nominal 210mm down to as little as 110mm. It sets the travel end but does not lock the load without continuous air pressure.
