About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX150-75S
The AirTAC SAIJ160X150-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 75 to 150 mm. The barrel features an extruded aluminum profile with sensor grooves on both sides, accommodating CMSE reed and DMSE electronic switches for precise end-of-travel detection.
This variant incorporates a SUS304 stainless steel rod for superior corrosion resistance and includes a PT tapered port thread. The rear adjuster functions strictly as a mechanical stop to fine-tune the retract position during commissioning; it does not lock the load. For applications requiring position holding without live air pressure, an external pilot-operated check valve or a BSAI clamp-lock cylinder 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 SAIJ160BX150-75S Is Used
Variable End-Stop Setup
Dial in the retract position from 75 to 150 mm during machine commissioning to accommodate different product sizes without adding external physical stops.
Corrosive Positioning
Rely on the SUS304 stainless steel rod for positioning tasks in washdown or mildly corrosive environments where standard carbon steel rods would fail.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX150-75S the Right Cylinder?
Selecting this 160 mm bore cylinder provides a maximum pull force of 9425 N at 0.5 MPa, making it a significant step up from the 100 mm bore (which offers 3681 N pull at 0.5 MPa) when heavy loads demand higher force. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers without physically swapping the cylinder. When replacing an ISO 15552 cylinder, match the 160 mm bore, 150 mm stroke, PT port, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options.
Because the 150 mm stroke is relatively short for this large bore, side-load risks are minimal, but an external guide is still recommended if the load is heavy or off-center. The operating speed ranges from 30-500 mm/s. The rear mechanical stopper and integrated air cushions manage end-of-stroke deceleration, but neither component acts as a brake or load-holding device.
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 SAIJ160BX150-75S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 75 mm, creating a usable travel window of 75 to 150 mm. This mechanical stop fine-tunes the retract end position during commissioning but does not lock the load without live air pressure.
