About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-50S
The AirTAC SAIJ160X155-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 105 to 155 mm, allowing you to dial back the nominal 155 mm stroke by up to 50 mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and because this variant includes a magnet (-S), it works seamlessly with AirTAC CMSE reed and DMSE solid-state switches.
This model is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. Unlike a fixed-stroke SAI, the external stopper lets you fine-tune the retract end position without swapping the cylinder or adding external stops. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true position holding, consider the SAIL or BSAI series.

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 SAIJ160BX155-50S Is Used
Heavy-Duty Pressing
Dial in the exact 105 to 155 mm end-position for large pressing or clamping operations without needing physical shims.
Machine Changeover
Quickly adapt the retract stroke during product line changeovers to accommodate different workpiece sizes.
Automated Assembly
Integrate CMSE or DMSE sensors via the dual-side grooves to confirm end-of-stroke positions in large-scale assembly jigs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-50S the Right Cylinder?
Choose this 160 mm bore adjustable cylinder when your application requires heavy thrust up to 14074 N at 0.7 MPa combined with variable end-stop positioning. The adjustable stroke is ideal for machine changeovers or product-size variations, letting you fine-tune the retract position on the fly.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 155 mm nominal stroke, 50 mm adjustment range, PT port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. Because the 155 mm stroke is relatively short for this large bore, side-loading is less severe than with extended strokes, but an external guide is still recommended for optimal seal life.
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 SAIJ160BX155-50S FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel down from the 155 mm nominal stroke to as little as 105 mm, creating a 50 mm adjustable window. This adjuster is a stop, not a lock, and will not hold the load without live air pressure.
