About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-100S
The AirTAC SAIJ160X950-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty applications. Featuring a 160mm bore, it generates 14074N of push force at 0.7 MPa. The integrated -100 adjustment code allows you to dial back the 950mm nominal stroke, providing an exact 850-950mm usable travel window for precise end-position tuning during commissioning. This model includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and a magnet (-S) for position sensing.
Because the stroke extends to 950mm, the 40mm diameter rod requires external guiding to prevent excessive side-loading and premature seal wear. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. You can fine-tune the retract end-position without swapping the cylinder or adding external stops, streamlining product changeovers on large automated lines.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-100S Is Used
Heavy Machinery Setup
Fine-tune the 850-950mm travel window during initial commissioning to perfectly dial in the retract position of large forming presses without machining new spacers.
Product Size Changeover
Adjust the rear stopper by up to 100mm on packaging lines to accommodate different pallet or product sizes quickly, minimizing downtime between production runs.
Variable End-Stop Actuation
Leverage the 10053N pull force at 0.5 MPa to move heavy fixtures, relying on the rear screw to set the precise resting position for multi-stage assembly operations.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-100S the Right Cylinder?
Select this 160mm bore cylinder when an application demands high thrust combined with variable end-stops, stepping up from a 125mm bore that provides 8590N push at 0.7 MPa. The adjustable stroke is ideal for machine setups requiring on-the-fly mechanical tuning rather than a fixed-stroke SAI cylinder. To match this exact configuration for an ISO 15552 replacement, specify the 950mm stroke, 100mm adjustment range, PT tapered port threads, and the -S magnet option.
For any stroke of 300mm or more, side-load management is critical; ensure your mounting arrangement—whether Basic, FA, LB, TC, FTC, TCM1, or TCM2—incorporates an external guide to support the load. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ160AX950-100S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides a push force of 14074N and a pull force of 13242N. At the maximum operating pressure of 1.0 MPa, it achieves a maximum push force of 2050 kgf.
The rear adjuster screw allows you to shorten the effective travel from the 950mm nominal stroke down to 850mm, creating a 100mm adjustable window. This stopper fine-tunes the end position at commissioning but does not lock the load without continuous air pressure.
