About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-40S
The AirTAC SAIJ160X80-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position at commissioning. With a nominal 80 mm stroke and a 40 mm adjustment range, it provides a highly flexible usable travel window of 40 to 80 mm without requiring external stops. Equipped with a SUS304 stainless steel rod, it is tailored for environments where corrosion resistance is a priority. In the 160 mm bore class, it delivers substantial power, generating 9425 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
This adjustable-stroke model integrates pneumatic cushions at both ends to manage deceleration across its 30-500 mm/s speed range. The extruded aluminum barrel features sensor grooves on both sides, and because this unit includes a magnet (-S), it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback. The robust 40 mm rod and M36x2 thread handle high side loads well, though an external guide remains essential for unsupported loads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-40S Is Used
Machine Changeover
Dial in the 40-80 mm travel window on the fly during product size transitions without swapping out the entire cylinder.
Commissioning Setup
Use the rear stopper screw to fine-tune the exact retract end position during initial machine commissioning, avoiding external shims.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable, high-force positioning in washdown or chemically exposed manufacturing settings.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-40S the Right Cylinder?
Choose this 160 mm bore adjustable cylinder when your application requires exact end-position tuning during machine setup or product changeover, stepping up from a 125 mm bore that yields 5734 N pull at 0.5 MPa. The rear adjuster acts strictly as a travel stop to dial in the 40-80 mm window, meaning it cannot hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series instead. To match this ISO 15552 interchangeable cylinder exactly, specify the 160 mm bore, 80 mm nominal stroke, 40 mm adjustment, PT tapered port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set, and the -S magnet option. Because the stroke is under 300 mm, side-load concerns are minimal, but always verify rod support in heavy push applications.
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 SAIJ160BX80-40S FAQ
This 160 mm bore cylinder generates 9425 N of pull force at 0.5 MPa and 18095 N at 0.9 MPa. The 40 mm adjustment screw allows you to trim the 80 mm nominal stroke, providing a usable travel window of 40 to 80 mm.
No, the rear adjuster functions only as a travel stop to set the end position, not as a mechanical lock. The cylinder requires live air pressure to hold a load; for fail-safe load holding, use a SAIL or BSAI series cylinder.
