About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-20S
The AirTAC SAIJ200X80-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 15708N push force at 0.5 MPa, utilizing a 40mm carbon steel rod and a G3/4 port. Featuring a -20 adjustment code, it transforms the fixed 80mm stroke into a 60-80mm usable travel window, allowing precise end-position tuning without swapping hardware.
This model includes a magnet (-S) for CMSE reed and DMSE electronic sensors, and uses SUS420J2 stainless steel (A) for the rod. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions. The rear screw acts purely as a travel stop for product changeovers, not a load lock, meaning live air is required to hold position.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-20S Is Used
Heavy Press Tuning
Fine-tune the 60-80mm travel window during commissioning to set exact pressing depths for heavy assemblies without adding external stopper blocks.
Product Changeovers
Quickly adjust the rear stopper on a packaging line to accommodate different product sizes, dialing back the stroke by up to 20mm in seconds.
High-Force Positioning
Leverage the 15708N thrust at 0.5 MPa to move heavy pallets into exact position, using the rear screw to set the precise retraction endpoint.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-20S the Right Cylinder?
Select this 200mm bore cylinder when an application demands high thrust (15708N push at 0.5 MPa) alongside variable end-stops. The adjustable 60-80mm window is ideal for machine setups requiring frequent product-size changeovers. If less force is needed, stepping down to a 160mm bore yields 10053N. For load-holding without live air pressure, a plain SAIJ is insufficient; consider an external rod lock or the AirTAC SAIL lock variant.
To match this ISO 15552 interchangeable cylinder, specify: 200mm bore, 80mm stroke, 20mm adjustment, PT tapered port threads, SUS420J2 rod material, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although the stroke is short, the heavy 40mm rod handles high side loads, but external guides are recommended for offset 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 SAIJ200AX80-20S 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 of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 80mm nominal stroke by up to 20mm, creating a 60-80mm usable travel window. It functions as a mechanical stop for end-position tuning and requires live air to hold the load.
