Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-40
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 140mm 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 SAIJ160X140-40
The AirTAC SAIJ160X140-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 10053N push force at 0.5 MPa and provides a usable travel window of 100 to 140 mm, letting you trim the nominal 140 mm stroke by up to 40 mm during commissioning.
This model uses a carbon steel rod with an M36x2 thread and a G3/4 port. The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not hold the load without live air pressure. For position holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-40 Is Used
Heavy Press Tuning
Dial in the exact 100 to 140 mm pressing depth for large assemblies, using the rear screw to fine-tune the final position without changing the cylinder.
Product Changeover
Adjust the end stop quickly on a mixed-model production line to accommodate different large-component heights, minimizing downtime between batches.
Fixture Setup
Set precise clamping distances during machine commissioning, using the 40 mm adjustment window to find the perfect travel limit before locking down the automation cycle.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-40 the Right Cylinder?
Choose this 160 mm bore cylinder when you need heavy thrust (10053N at 0.5 MPa) that exceeds the 80 mm class (2513N) but falls below the massive 200 mm class (15708N). The 40 mm adjustment range is ideal for product changeovers on the line, allowing you to shift the end stop without physically swapping the cylinder or bolting on external stops. If your process requires a fixed end position every cycle, the standard SAI series is a simpler alternative.
When matching ISO 15552 dimensions for a replacement, verify the 140 mm stroke, 40 mm adjuster, G3/4 PT port, and standard carbon steel rod. Because this is a large-bore cylinder, ensure your mounting choice from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) adequately supports the mass, as the SAIJ line omits the FB, CA, CB, and CR mounts.
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 SAIJ160X140-40 FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053N of push thrust and 9425N of pull thrust. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 140 mm down to 100 mm. It sets the end position but does not lock the load without continuous air pressure.
