About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-20S
The AirTAC SAIJ80X160-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables seamless position feedback using AirTAC CMSE reed or DMSE electronic solid-state sensors housed within the dual-side extruded aluminum barrel grooves.
This specific SKU provides a nominal 160mm stroke that can be fine-tuned down by up to 20mm, creating a precise 140-160mm usable travel window. It features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threading (G3/8) for secure pneumatic connections. The rear adjuster acts purely as a mechanical stop to dial in end positions during commissioning without requiring external stops.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-20S Is Used
Precision End-Stop Tuning
Dial in the exact 140-160mm travel distance during machine commissioning to accommodate slight mechanical variances without adding external stopper blocks.
Product Size Changeover
Quickly adjust the retract end-position by up to 20mm on packaging lines when switching between different product sizes, minimizing downtime.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-20S the Right Cylinder?
The adjustable 140-160mm travel window is ideal for machinery requiring exact end-position tuning during product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder. To match this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 80mm bore, 160mm nominal stroke, 20mm adjustment range, PT port thread, and the -S magnet option.
Because the stroke is 160mm, the 25mm rod diameter and M20x1.5 rod thread provide excellent structural rigidity, though any long unsupported loads should still utilize an external guide. Remember that the rear adjuster only sets the travel end and does not hold the load without live air; for true pneumatic locking without pressure, consider the SAIL or BSAI series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ80 Adjustable Cylinder SAIJ80BX160-20S FAQ
The rear mechanical adjuster allows you to shorten the effective travel from the nominal 160mm down to 140mm, creating a 140-160mm usable window. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
