About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-100S
The AirTAC SAIJ160X270-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 18095N at 0.9 MPa. With a nominal 270 mm stroke and a 100 mm adjustment range, it provides an exact 170-270 mm usable travel window for highly precise end-position tuning. This bore features a robust 40 mm piston rod, G3/4 porting, and operates at speeds of 30-500 mm/s.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and a built-in magnet (-S) for position sensing. The extruded aluminum barrel features sensor grooves on both sides, allowing you to easily mount AirTAC CMSE reed or DMSE electronic solid-state switches. The rear stopper screw allows you to dial in the retract position during commissioning without adding external stops, though it acts only as a travel stop and not a lock.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-100S Is Used
Heavy Machinery Changeover
Dial in the 170-270 mm travel window during product size changes on large equipment without physically replacing the actuator.
Press End-Stop Tuning
Fine-tune the retract position of heavy pressing or clamping operations at commissioning using the rear stopper screw.
Corrosive Environment Handling
Leverage the SUS304 stainless steel rod for large-scale positioning tasks in washdown or mildly corrosive industrial settings.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-100S the Right Cylinder?
The 100 mm adjustment window is ideal for product changeovers on large machinery, letting you shift the end-stop from 170 to 270 mm on the fly instead of swapping the entire cylinder. For fixed-position tasks without variation, a standard SAI cylinder is simpler.
Because this is a 270 mm stroke, the 40 mm SUS304 rod handles high side loads well, but an external guide is still recommended for heavy off-center loads to prevent premature seal wear. To replace an ISO 15552 cylinder, match the 160 mm bore, 270 mm stroke, 100 mm adjust, PT tapered ports, and the -S magnet. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear adjuster and air cushions do not hold the load without live air; use a SAIL or BSAI lock cylinder for fail-safe holding.
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 SAIJ160 Adjustable Cylinder SAIJ160BX270-100S FAQ
Its maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 270 mm down to 170 mm. This provides a 170-270 mm travel window for setup flexibility, but it does not lock the load without live air pressure.
