About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-20
The AirTAC SAIJ160X165-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. By turning the external stopper screw, you can fine-tune the effective travel within a 145-165 mm window during commissioning without adding external stops.
This unit is built with an SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a PT tapered port thread. The extruded aluminum barrel integrates sensor grooves on both sides, allowing you to mount CMSE reed or DMSE solid-state switches directly. The rear adjuster functions purely as a travel stop to set end positions, not as a lock to hold loads 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 SAIJ160BX165-20 Is Used
Machine Changeover
Dial in the 145-165 mm travel window during product size transitions to set new end positions quickly without physically replacing the cylinder.
End-Position Tuning
Fine-tune the retract end position during commissioning to compensate for mechanical wear or slight misalignments in your fixture setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-20 the Right Cylinder?
The 20 mm adjustment range is ideal for product-size changeovers on a line, letting operators dial in the new end position rapidly rather than swapping out a fixed-stroke SAI cylinder. For any load-holding requirements without continuous air pressure, this cylinder is not suitable; instead, specify an SAIL air-released lock or a BSAI clamp-lock cylinder.
When configuring an ISO 15552 replacement, match the 160 mm bore, 165 mm stroke, 20 mm adjustment, PT port thread, and SUS304 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because the 165 mm stroke is relatively short for this large bore, side-load risks are minimal, but an external guide is still recommended for heavy offset loads.
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 SAIJ160BX165-20 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the 165 mm nominal stroke by up to 20 mm, creating a usable travel window of 145 to 165 mm. It only sets the travel end position and does not lock or hold the load without live air pressure.
