About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-20
The AirTAC SAIJ160X155-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that creates a usable travel window of 135-155 mm. Delivering a substantial 18095 N pull force at 0.9 MPa, it handles heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, and this specific configuration uses a SUS304 stainless steel rod for superior corrosion resistance.
Equipped with a PT tapered port and a 50 mm air cushion at both ends, it safely decelerates massive loads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not hold the load without live air pressure. For load-holding requirements, an external rod lock or the AirTAC SAIL series is required.

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 SAIJ160BX155-20 Is Used
Heavy Press Tuning
Fine-tune the exact end-stop position of a heavy-forming press during setup, using the 20 mm adjustment window to compensate for tooling tolerances.
Assembly Line Changeover
Quickly adapt a machinery station to a new product variant by dialing back the retract stroke by up to 20 mm without swapping out the entire cylinder.
Corrosive Environment Handling
Utilize the SUS304 stainless steel rod in washdown or mildly corrosive manufacturing areas where carbon steel rods would degrade over time.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-20 the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires the 9425 N pull force available at 0.5 MPa but demands exact end-position tuning without adding external stops. The 20 mm adjustment window is ideal for accommodating slight mechanical variations during machine assembly or product changeovers. Unlike a fixed-stroke SAI cylinder, the SAIJ allows you to dial in the exact retract distance on-site.
Because the 155 mm stroke is below the 300 mm threshold, side-load risks are moderate, but the robust 40 mm SUS304 rod and M36x2 thread handle high bending stresses well. When specifying a replacement, match the 160 mm bore, 155 mm stroke, 20 mm adjust, PT port, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set. If position holding without live air is needed, step up to a SAIL or BSAI lock cylinder.

- ✓ 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 SAIJ160BX155-20 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 155 mm stroke by up to 20 mm, creating a usable travel window of 135-155 mm. The adjuster only sets the end position and does not lock or hold the load without continuous air pressure.
