About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX150-20S
The AirTAC SAIJ160X150-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 150 mm nominal stroke by up to 20 mm for a precise 130-150 mm usable travel window. Belonging to the 160 mm bore class, it generates massive thrust up to 14074 N at 0.7 MPa, making it suitable for heavy-duty pressing and clamping. This variant features a robust SUS304 stainless steel rod for superior corrosion resistance.
This model includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors, which mount cleanly into the dual sensor grooves on the extruded aluminum barrel. The rear adjuster functions purely as a mechanical stop to fine-tune the end position during commissioning without requiring external stops; it is not a locking device and will not hold the load without live air pressure.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX150-20S Is Used
Heavy-Duty Press Fitting
Dial in the exact 130-150 mm end-stop during press-fitting operations to accommodate slight variations in part tolerances without swapping cylinders.
Product Line Changeover
Quickly adjust the rear stroke stop when switching between different product sizes on a high-force assembly line, reducing machine setup downtime.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX150-20S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, providing tuning flexibility that a fixed-stroke SAI cylinder cannot offer. If your process demands true load-holding without continuous air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock series instead of relying on the adjuster.
For an exact ISO 15552 replacement, match the 160 mm bore, 150 mm stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet option. Because this cylinder operates at speeds of 30-500 mm/s and handles high forces, ensure your mounting choice from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 sets rigidly supports the load to prevent side-loading on the large 40 mm rod.
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 SAIJ160BX150-20S FAQ
The rear mechanical stopper allows you to shorten the 150 mm nominal stroke by up to 20 mm, creating a usable travel window of 130-150 mm. This enables precise end-position tuning at commissioning without adding external stops.
