About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-100S
The AirTAC SAIJ160X350-100-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a robust 160mm bore generating 14074N of push force at 0.7MPa, alongside a generous 350mm nominal stroke that can be dialed back by up to 100mm. This creates a precise 250-350mm usable travel window, allowing operators to fine-tune retract distances during commissioning without swapping out the entire unit.
Equipped with a SUS304 stainless steel rod (code B) for superior corrosion resistance, this model includes a magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel houses sensor grooves on both sides, and the rear adjuster functions strictly as a mechanical stop to set the travel limit, not as a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-100S Is Used
Heavy-Duty Press Tuning
Dial in the exact 250-350mm retract position during press setup to accommodate different material thicknesses without changing the cylinder.
Product Size Changeover
Quickly adjust the end-stop on automated assembly lines when switching between large product variants, minimizing machine downtime.
Actuator Commissioning
Fine-tune the final resting position of heavy payloads during initial machine commissioning to perfect timing and mechanical alignment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-100S the Right Cylinder?
Selecting this 160mm bore cylinder provides 14074N push force at 0.7MPa, offering a substantial step up from the 100mm bore class which provides 5497N. If your application requires less force, stepping down to the 125mm bore (8590N at 0.7MPa) might suffice. The 100mm adjustment range is ideal for production lines handling frequent product-size changes, delivering variable end-stops without the need to bolt on external stops or purchase a fixed-stroke SAI cylinder.
Because this unit features a 350mm stroke, the 40mm diameter rod and M36x2 thread provide excellent rigidity, but an external guide is still recommended to manage side loads on long unsupported travels. For load-holding without live air pressure, this cylinder is insufficient as the rear adjuster is only a travel stop; you should explore an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. To ensure exact ISO 15552 replacement compatibility, verify the 350mm stroke, 100mm adjustment, PT tapered port thread, and your preferred mounting option from the available Basic, FA, LB, TC, FTC, TCM1, and TCM2 set.

- ✓ 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 SAIJ160BX350-100S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. At the maximum operating pressure of 1.0 MPa, it achieves a maximum push force of 10053 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 250-350mm from the nominal 350mm stroke, enabling precise end-position tuning without replacing the cylinder.
