About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-30S
The AirTAC SAIJ160X180-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 180 mm nominal travel by up to 30 mm. This creates a highly useful 150-180 mm usable stroke window, letting you fine-tune the retract end position during commissioning without adding external stops. It delivers substantial thrust, pushing with 14074 N and pulling with 9425 N at 0.7 MPa.
Built with a SUS304 stainless steel rod (option B) and PT tapered ports, this 160 mm bore unit is ready for harsher environments. The extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic solid-state sensors. The rear adjuster functions purely as a travel stop for end-position tuning, not as a locking device, so live air is required to hold the load.

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 SAIJ160BX180-30S Is Used
Machine Changeover
Dial in the exact 150-180 mm retract position during product size transitions without physically replacing the cylinder or adding external mechanical stops.
Commissioning Calibration
Fine-tune the end-of-stroke position during initial setup to perfect timing and kinematics, absorbing mechanical tolerances across the fixture.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-30S the Right Cylinder?
The adjustable stroke is ideal for machine changeovers where the exact retract position varies slightly between product sizes, eliminating the need to swap out a fixed-stroke SAI cylinder. When matching an ISO 15552 replacement, specify the 160 mm bore, 180 mm stroke, 30 mm adjustment, PT ports, and the -S magnet. For strokes of 300 mm or more, an external guide is recommended to handle side loads, though this 180 mm unit operates well within standard limits. Remember that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. If you need true load-holding without live air pressure, look to the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ160BX180-30S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push (extend) force of 14074 N and a pull (retract) force of 9425 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 180 mm nominal stroke by up to 30 mm, providing a usable travel window between 150 mm and 180 mm. It only sets the end position and does not lock the load without live air pressure.
