About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX110-20S
The AirTAC SAIJ200X110-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 110 mm stroke that can be dialed back by up to 20 mm, yielding a precise 90-110 mm usable travel window for commissioning without external stops. In this B configuration, it features a SUS304 stainless steel piston rod paired with a PT tapered port thread, delivering a robust 15708 N push force at 0.5 MPa.
This adjustable model retains the standard extruded aluminum barrel with sensor grooves on both sides. Because it includes a magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state switches for exact position sensing. The rear adjustment screw functions strictly as a travel stop to fine-tune the end position, not as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX110-20S Is Used
Variable End-Stop Tuning
Dial in the exact 90 to 110 mm retraction point during machine commissioning to accommodate varying material thicknesses without adding external physical stops.
Product Size Changeovers
Quickly adjust the effective stroke length on automated lines when switching between different product dimensions, minimizing downtime between production runs.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to move heavy pallets or fixtures into a precise end position that can be fine-tuned on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX110-20S the Right Cylinder?
Step down to a 160 mm bore if your application requires less force, as that size yields 10053 N push at 0.5 MPa, but keep the 200 mm bore when maximum thrust is necessary. Choose this adjustable-stroke version over a fixed SAI when you need variable end-stops for product changeovers or fine-tuning at setup. To replace an ISO 15552 cylinder, match the 200 mm bore, 110 mm stroke, 20 mm adjustment, PT G3/4 port, and the -S magnet. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and CA options.
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 SAIJ200BX110-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It reaches a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the 110 mm nominal stroke by up to 20 mm. This creates a 90-110 mm usable travel window, allowing you to set the exact end position without swapping the cylinder.
