About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-75S
The AirTAC SAIJ160X220-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 14074N of push force at 0.7 MPa. It features a SUS304 stainless steel rod and a built-in magnet for position sensing. The integrated adjuster allows you to trim the 220mm nominal stroke back by up to 75mm, creating a precise 145 to 220mm usable travel window for highly controlled end-position tuning.
This adjustable stop is ideal for product changeovers, letting you fine-tune the retract position without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-load holding, consider an external rod lock or the SAIL series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 145-220mm window during machine commissioning to accommodate different material thicknesses without mechanical rebuilds.
Product Size Changeover
Quickly adjust the stroke stop on automated packaging lines when switching between different container sizes, minimizing downtime and maximizing line flexibility.
Heavy-Duty Positioning
Leverage the 14074N push force and rigid 40mm SUS304 rod to move heavy pallets or fixtures into a precise end position before secondary clamping operations.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-75S the Right Cylinder?
Choose this 160mm bore when a 100mm bore (providing 5497N push at 0.7 MPa) is insufficient, but a 200mm bore (delivering 21991N) would be excessive overkill. The generous 75mm adjustment window is perfect for prototyping or production lines running mixed product sizes, whereas a fixed-stroke SAI cylinder is better suited for single, unchanging end-of-stroke applications. Because the 220mm stroke exceeds 300mm? No, it is under 300mm, but with a heavy 40mm rod and M36x2 thread, it handles high side loads well, though an external guide is always recommended for heavy off-center loads.
To match this exact ISO 15552 interchangeable footprint, specify: 160mm bore, 220mm stroke, 75mm adjustment, PT tapered port thread, SUS304 (B) rod material, and the -S magnet option. Standard mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR variants.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX220-75S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 18095N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 220mm nominal stroke by up to 75mm, providing a usable travel window of 145 to 220mm. It only sets the end position and does not lock the load without continuous air pressure.
