About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-100
The AirTAC SAIJ160X500-100 is a double-acting ISO 15552 profile cylinder featuring a robust 160mm bore and a 500mm stroke. Equipped with a rear mechanical adjuster, it provides a usable travel window of 400-500mm, allowing you to dial back the extension by up to 100mm during commissioning. It delivers massive thrust, pushing with 18095N at 0.9 MPa, making it ideal for heavy-duty machinery. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This variant uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads (G3/4). The rear adjuster acts strictly as a travel stop to set the end position; it does not lock or hold the load without live air pressure. For applications requiring position holding without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-100 Is Used
Heavy Machinery Changeover
Ideal for large presses and heavy equipment where the 100mm stroke adjustment allows rapid adaptation to different material thicknesses without changing the cylinder.
Precision End-Stop Tuning
Dial in the exact 400-500mm travel window during machine commissioning to perfect end-of-stroke positioning without adding external mechanical stops.
Corrosive Metal Forming
The SUS304 stainless steel rod handles harsh environments while delivering 18095N push force at 0.9 MPa for demanding forming and clamping tasks.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-100 the Right Cylinder?
Select this 160mm bore cylinder when your application requires high force, generating 14074N push at 0.7 MPa, stepping up from the 125mm bore which yields 8590N at the same pressure. The 100mm adjustment range is perfect for product changeovers, letting you fine-tune the end stop without swapping cylinders or adding external stops. Since this is a 500mm stroke, the 40mm diameter SUS304 rod will experience leverage on long unsupported extensions; always use an external guide to prevent side-load damage.
When replacing an ISO 15552 cylinder, match these exact specs: 160mm bore, 500mm stroke, 100mm adjustment range, PT G3/4 port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable variant. Operating speed is 30-500 mm/s.

- ✓ 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 SAIJ160BX500-100 FAQ
It features a rear mechanical stopper that lets you shorten the nominal 500mm stroke by up to 100mm, providing an adjustable travel window of 400-500mm. The adjuster acts as a travel stop and does not lock the load without live air pressure.
At 0.9 MPa operating pressure, this 160mm bore double-acting cylinder generates a push force of 18095N and a pull force of 9425N. Its maximum thrust at 1.0 MPa is 2050 kgf.
