About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-100
The AirTAC SAIJ160X350-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel. With a 350mm nominal stroke and a 100mm adjustment range, it provides a usable travel window of 250-350mm for exact end-position tuning. It delivers substantial force, offering 14074N push and 9425N pull at 0.7MPa.
This bore uses a robust 40mm piston rod with an M36x2 thread, paired with 50mm cushions at both ends to handle heavy kinetic energy. The rod is constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and the barrel is an extruded aluminum profile with sensor grooves on both sides. The pneumatic supply connects via a PT G3/4 port, and the recommended operating speed is 30-500mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-100 Is Used
Heavy Press Tuning
Dial in the exact 250 to 350mm travel window on heavy presses during commissioning to accommodate material thickness variations without external stopper blocks.
Product Changeover
Rapidly adjust the retract end-position on automated lines during product size changeovers, saving downtime by turning the rear screw instead of replacing the cylinder.
Large Assembly Jigs
Fine-tune the end-stop on large assembly jigs where a fixed 350mm stroke might over-travel, ensuring delicate components are not crushed during the final approach.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-100 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when your machine setup requires commissioning fine-tuning or variable end-stops without physically swapping the cylinder or adding external stops. If you need to step down force, the neighboring 125mm bore provides 8590N push at 0.7MPa. To replace an ISO 15552 cylinder, match the 160mm bore, 350mm stroke, 100mm adjustment, PT G3/4 port, and your required mounting style.
Because the 350mm stroke is substantial, the 40mm rod diameter provides excellent rigidity, but long unsupported strokes still require an external guide to prevent side-loading damage. The rear adjuster acts purely as a mechanical stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider the SAIL or BSAI series. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ160BX350-100 FAQ
At 0.7MPa operating pressure, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. It can reach a maximum push force of 18095N at 0.9MPa.
The rear adjuster screw lets you shorten the nominal 350mm stroke by up to 100mm, creating a usable travel window of 250-350mm. It functions as a mechanical stop to set the retract end-position and does not lock the load without live air.
