About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-40S
The AirTAC SAIJ200X160-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 160 mm travel to anywhere within a 120-160 mm usable window. Built with an extruded aluminum barrel, it delivers massive thrust—15708 N push at 0.5 MPa—making it suitable for heavy-duty pressing and clamping.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The rear stopper acts purely as a travel end-position setter for product changeovers; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-40S Is Used
Heavy Pressing Operations
Apply up to 21991 N of push force at 0.7 MPa for forming and stamping, using the 40 mm adjuster to set the exact 120-160 mm bottoming position.
Product Size Changeovers
Quickly reconfigure the rear stopper on a packaging line to accommodate different product heights without physically replacing the cylinder.
Industrial Clamp Tuning
Secure large workpieces by fine-tuning the clamping travel window during setup, relying on the robust SUS420J2 stainless steel rod.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-40S the Right Cylinder?
Choose this 200 mm bore when 100 mm (5497 N push at 0.5 MPa) is insufficient for your high-force application. The adjustable 120-160 mm window is ideal for fine-tuning end stops during machine commissioning without swapping hardware. If your process requires true load-holding without continuous air pressure, a standard SAIJ is insufficient—consider an AirTAC SAIL or BSAI locking cylinder instead.
For a drop-in ISO 15552 replacement, match the 200 mm bore, 160 mm stroke, 40 mm adjustment code, PT tapered port threads, and the -S magnet. Because the stroke is 160 mm, standard mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. While the 40 mm rod and M36x2 thread handle high side loads well, always use an external guide for heavy unsupported loads.
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 SAIJ200AX160-40S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster allows you to shorten the 160 mm nominal stroke by up to 40 mm, creating a usable travel window of 120-160 mm. This stopper only sets the end position; it does not lock the load.
