About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-10S
The AirTAC SAIJ200X375-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster. It features a 200mm bore, a SUS420J2 stainless steel rod, and a PT tapered port. As a made-to-order non-standard stroke unit, it provides a 375mm nominal stroke that can be fine-tuned backward by up to 10mm, creating a precise 365-375mm usable travel window. Operating at 30-500 mm/s, it delivers a robust 15708N push force at 0.5 MPa and 21991N at 0.7 MPa.
Because it includes a magnet (-S), this model directly supports AirTAC CMSE reed and DMSE electronic sensors housed in the extruded aluminum barrel's dual sensor grooves. The external rear stopper allows you to dial in the retract end-position during commissioning without adding external stops. Note that this adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-10S Is Used
Heavy Press Tuning
Dial in the exact 365-375mm retract position on heavy pressing machinery without swapping out components or adding external mechanical stops.
Product Changeover
Adjust the travel window on the fly during line changeovers to accommodate different product sizes while maintaining 15708N of thrust.
Large Assembly Jigs
Secure and position large automotive or industrial assemblies with the SUS420J2 rod, using DMSE sensors to confirm exact end positions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-10S the Right Cylinder?
Choose this 200mm bore cylinder when your application requires maximum thrust in the SAIJ range, such as 15708N push force at 0.5 MPa, and you need a 365-375mm travel window for product-size changeovers. If you need less force, stepping down to a 160mm bore yields 10053N at 0.5 MPa. The adjustable stroke is ideal for fine-tuning end positions at setup, whereas a fixed-stroke SAI lacks this built-in flexibility.
For ISO 15552 replacement matching, verify a 200mm bore, 375mm stroke, 10mm adjustment, PT G3/4 port, and a -S magnet. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 375mm stroke is long and the rod is heavy, external guides are recommended to prevent excessive side-loading. For load-holding without live air, use a SAIL or BSAI cylinder 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 SAIJ200AX375-10S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster screw allows you to shorten the 375mm nominal stroke by up to 10mm, resulting in a 365-375mm usable travel window. It acts as a mechanical stop and does not lock the load without live air.
