About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-10S
The AirTAC SAIJ200X900-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 890-900 mm. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The barrel features sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches.
This variant features a SUS420J2 stainless steel rod (material code A) and PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock or hold the load without live air pressure. For applications requiring position holding without continuous air, an external rod lock or related types like SAIL or BSAI are required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-10S Is Used
Heavy Press Tuning
Dial in the exact 890-900 mm end position during heavy press commissioning without adding external mechanical stops.
Large Mold Changeover
Adjust the retract stop on the fly to accommodate varying large mold sizes during production line changeovers.
Heavy Pallet Positioning
Fine-tune the stopping point for heavy pallets or large workpieces, ensuring precise alignment before secondary operations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-10S the Right Cylinder?
Choose this 200 mm bore cylinder when a 160 mm bore (which pushes 10053 N at 0.5 MPa) lacks the necessary force for your heavy loads. The adjustable stroke is ideal for fine-tuning the retract end position during machine setup or product changeover without swapping the cylinder or adding external stops. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
When specifying an ISO 15552 replacement, match the 200 mm bore, 900 mm stroke, 10 mm adjustment, PT ports, and the -S magnet. Because the stroke is 900 mm, the 40 mm rod diameter and M36x2 thread will not prevent rod sag; an external guide is strongly recommended to manage side loads and prevent premature seal wear.
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 SAIJ200AX900-10S FAQ
At 0.5 MPa operating pressure, it provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw lets you trim the effective travel back by up to 10 mm from the 900 mm nominal stroke, creating an 890-900 mm window. It functions as an end stop and does not lock the load without live air.
