About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-30
The AirTAC SAIJ160X300-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 300 mm nominal stroke by up to 30 mm for a precise 270-300 mm usable travel window. It delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is supplied without a magnet. You can fine-tune the retract end position during commissioning without swapping hardware or adding external stops.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-30 Is Used
Heavy Press Tuning
Dial in the exact 270-300 mm end position during heavy press setup to accommodate material thickness variations without remounting the cylinder.
Product Changeover
Adjust the retract stop on the fly when switching between different pallet sizes on a high-thrust conveyor sorting line.
Large Fixture Alignment
Fine-tune the clamping reach on large automated fixtures, relying on the 10053 N pull force to secure heavy metal components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-30 the Right Cylinder?
Select this 160 mm bore when a 100 mm bore falls short (delivering only 3681 N pull at 0.5 MPa) but you want to avoid the massive 15708 N push force of a 200 mm bore. The adjustable 270-300 mm window is ideal for product changeovers, letting you set variable end-stops on the fly instead of machining new hard stops. For load-holding without live air pressure, note that the rear adjuster acts only as a travel stop and not a brake; you would need an external rod lock or a SAIL/BSAI cylinder for secure clamping.
Because the 300 mm stroke is relatively long for this large bore, ensure adequate external guidance to prevent excessive side-loading on the SUS304 rod. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. To match this unit exactly, specify the 160 mm bore, 300 mm stroke, 30 mm adjustment, PT port thread, SUS304 rod, and no magnet.
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 SAIJ160BX300-30 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from its 300 mm nominal length down to 270 mm. This allows precise end-position tuning at commissioning without adding external stops, though it does not lock the load without live air.
