Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-20S
The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX190-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 190mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-20S
It features a 190mm nominal stroke that can be fine-tuned down by up to 20mm, creating a precise 170-190mm usable travel window. The SUS304 stainless steel rod provides excellent corrosion resistance for harsh environments.
This model includes a magnet for position sensing and operates at 30-500mm/s. The rear screw acts purely as a travel stop for product changeovers and does not hold the load without live air. It shares the standard ISO 15552 mounting interface but uses a reduced bracket set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160BX190-20S Is Used
Heavy Press Fit Tuning
Dial in the exact 170-190mm insertion depth for large bearings during assembly, allowing on-the-fly adjustments without swapping physical cylinder stops.
Product Size Changeover
Adapt automated heavy-duty machinery to different product lengths by simply turning the rear adjuster screw to trim the retraction point quickly.
Precision End-Stop Calibration
Achieve perfect end-position tuning at machine commissioning, using the 20mm adjustment window to compensate for mechanical tolerance stack-up.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-20S the Right Cylinder?
The adjustable 170-190mm window is ideal for dialing in exact end stops during commissioning without adding external stops. For load-holding without live air pressure, integrate an external rod lock or explore the AirTAC SAIL or BSAI series.
To match this exact configuration for an ISO 15552 replacement, specify: 160mm bore, 190mm stroke, 20mm adjustment, PT tapered port, SUS304 (B) rod material, and the -S magnet for CMSE reed or DMSE electronic sensors. Because the stroke is under 300mm, side-load stress is manageable, but always ensure adequate external guiding for the 40mm rod and M36x2 thread.
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 SAIJ160BX190-20S FAQ
The rear adjuster screw lets you shorten the 190mm nominal stroke by up to 20mm, providing a usable travel window of 170-190mm. This stopper only sets the travel end and requires live air to maintain position; it does not lock the load.
