About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-20S
The AirTAC SAIJ160X140-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end-position during commissioning. It provides a usable travel window of 120-140 mm, letting you trim the nominal 140 mm stroke by up to 20 mm without adding external stops.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and ships with a piston magnet for position sensing. It uses PT tapered G3/4 ports and operates at speeds of 30-500 mm/s. The extruded aluminum barrel features sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160BX140-20S Is Used
Press Tuning
Dial in the exact 120-140 mm end-stop during machine commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover
Quickly adjust the retract position on automated assembly lines when switching to a new product size, saving setup time.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-20S the Right Cylinder?
The adjustable stroke is ideal for product changeovers, allowing you to dial in the travel window from 140 mm down to 120 mm. For load-holding without live air pressure, note that the rear adjuster is a travel stop, not a lock; you would need an external rod lock or a SAIL pneumatic lock cylinder for fail-safe holding.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 140 mm stroke, 20 mm adjustment range, PT G3/4 port, and the -S magnet requirement. Because the 40 mm rod and M36x2 thread handle high side loads, ensure your mounting choice from the SAIJ subset (which omits FB, CA, CB, and CR brackets) properly supports the load.
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 SAIJ160BX140-20S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 20 mm, providing a usable travel window of 120-140 mm. It is a travel stop for end-position tuning, not a lock, and does not hold the load without live air pressure.
