About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-40
The AirTAC SAIJ160X750-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 710-750 mm window. Delivering a substantial 9425 N pull force at 0.5 MPa, this large-bore actuator is built for heavy-duty positioning. It features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
Unlike a fixed-stroke SAI cylinder, the integrated rear stopper screw lets you dial in the exact retract position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the standard air cushions at both ends manage deceleration across the 30-500 mm/s speed range.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-40 Is Used
Heavy Machinery Changeover
Dial in the 710-750 mm retract position during heavy equipment format changes without swapping the actuator or fabricating external stop blocks.
Press End-Position Tuning
Fine-tune the retract stop on large presses to accommodate material thickness variations, relying on the 18095 N push force at 0.9 MPa.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable heavy-duty positioning in washdown or chemically exposed manufacturing settings.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-40 the Right Cylinder?
Choose this 160 mm bore when the 100 mm class (providing 3681 N pull at 0.5 MPa) is insufficient, but a 200 mm bore is physically too large. The 40 mm adjustment range is ideal for precisely setting end-of-stroke limits during product changeovers on heavy machinery. Because the nominal stroke is 750 mm, the long unsupported piston rod requires an external guide to prevent excessive side-load wear.
For an ISO 15552 dimensional replacement, match the 160 mm bore, 750 mm stroke, 40 mm adjuster, PT G3/4 ports, and the SUS304 (B) rod material. Remember that the rear adjuster acts only as a travel stop; it will not hold the load without live air pressure. For true fail-safe load holding, select an SAIL or BSAI cylinder instead.
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 SAIJ160BX750-40 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw acts as a mechanical stop that shortens the retract stroke. For this SAIJ160X750-40 model, you can trim the effective travel back by up to 40 mm, creating a 710-750 mm usable window without changing the cylinder itself.
