About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-100S
The AirTAC SAIJ200X400-100-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. The built-in rear stopper provides a usable travel window of 300-400mm, allowing you to trim the 400mm nominal stroke by up to 100mm without adding external stops.
This heavy-duty unit features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. Fluid must be filtered to 40 um, and the cylinder operates at speeds between 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-100S Is Used
Heavy Press Tuning
Dial in the exact end position of high-tonnage pressing operations within the 300-400mm window during setup.
Product Changeovers
Quickly adapt large automated machinery to new product sizes by adjusting the rear stopper without mechanical rebuilds.
Long-Stroke Positioning
Handle heavy loads over a 400mm travel with fine-tune capability, relying on external guides to support the rod.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-100S the Right Cylinder?
Choose this 200mm bore when a 160mm bore (providing 10053N push at 0.5 MPa) cannot meet your force requirements. The adjustable stroke is perfect for heavy machinery commissioning, letting you fine-tune the retract end position during product changeovers rather than swapping cylinders. To replace an ISO 15552 cylinder, match the 400mm stroke, 100mm adjustment, PT tapered ports, and the -S magnet.
Because the stroke is 400mm, the 40mm rod and M36x2 thread still require an external guide to handle side loads on long unsupported travels. Note that the rear adjuster acts only as a travel stop, not a lock; the SAIJ does not hold loads without live air, so consider a SAIL or BSAI cylinder for load-holding applications.
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 SAIJ200AX400-100S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa operating pressure, it reaches a maximum push force of 3204 kgf.
The rear adjuster acts as a stopper that lets you mechanically shorten the effective stroke. For this SAIJ200X400-100-S model, you can trim the 400mm nominal stroke back by up to 100mm, creating a usable travel window of 300-400mm.
