Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 195mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40
The AirTAC SAIJ160X195-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 18095N of push force at 0.9 MPa, making it suited for heavy-duty positioning tasks. A standard carbon steel rod with an M36x2 thread handles high axial and side loads, while the PT (tapered) G3/4 porting ensures high airflow for rapid cycling within the 30-500 mm/s speed range.
This specific SKU provides a 155-195 mm usable travel window, allowing you to dial back the nominal 195 mm stroke by up to 40 mm. The external rear screw acts purely as a mechanical stop for end-position tuning during commissioning; it does not lock the load without live air. For load-holding requirements without continuous pressure, consider the related SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40 Is Used
Heavy-Duty Forming
Dial in the exact 155-195 mm end-stop during machine setup to accommodate varying material thicknesses in large metal forming or pressing operations.
Product Changeover Stops
Adjust the rear stopper on the fly to handle different package sizes on a heavy-duty conveyor line without physically replacing the actuator.
Large Assembly Positioning
Leverage the 18095N push force to move heavy pallets or structural components, fine-tuning the final resting position at the commissioning stage.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40 the Right Cylinder?
Select this 160 mm bore when your application requires forces between 14074N at 0.7 MPa and 18095N at 0.9 MPa, but a 125 mm bore (offering 11045N at 0.9 MPa) would fall short of your push requirements. The adjustable 155-195 mm travel window is ideal for production lines that require variable end-stops or frequent product-size changeovers without swapping out the entire cylinder body.
When matching this as an ISO 15552 replacement, verify your porting (PT G3/4), the 195 mm nominal stroke with a 40 mm adjustment, and your mounting choice from the available SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this unit lacks a magnet, position sensing is not possible without upgrading to an -S variant for CMSE or DMSE switches. For any stroke at or above 300 mm, an external guide is recommended to prevent excessive rod side-loading, though this 195 mm stroke is well within standard limits.
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 SAIJ160X195-40 FAQ
At the maximum operating pressure of 1.0 MPa, this 160 mm bore cylinder generates 2050 kgf. At 0.9 MPa it provides 18095N of push force and 9425N of pull force.
The rear adjuster screw allows you to shorten the effective travel from the 195 mm nominal stroke down to 155 mm. This mechanical stop fine-tunes the retract end position during setup but does not hold the load dynamically without live air pressure.
