About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-50
The AirTAC SAIJ160X105-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 10053N push force at 0.5MPa and features a 105mm nominal stroke that can be fine-tuned down by up to 50mm, yielding a usable travel window of 55-105mm. This built-in adjustability allows operators to dial in the exact retract end-position during commissioning without swapping out the entire unit.
Built with a standard carbon steel piston rod and a PT tapered port thread, this extruded aluminum barrel design integrates sensor grooves on both sides for flexible switch mounting. It supports a reduced set of ISO 15552 mounting interfaces including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. The rear stopper mechanism relies on live air to maintain position and is not a locking device.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-50 Is Used
Heavy Press Fine-Tuning
Dial in the exact clamping end-position on high-tonnage forming presses without adding external mechanical stops.
Product Size Changeover
Quickly adjust the retract distance by up to 50mm when switching between different product heights on a heavy assembly line.
Actuator Commissioning
Trim the 105mm stroke to precise machine clearances during initial setup to prevent over-travel damage.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-50 the Right Cylinder?
Choose this 160mm bore cylinder when an application demands high thrust, such as the 10053N push or 9425N pull at 0.5MPa, alongside variable end-stop positioning. If the 50mm adjustment range is excessive or the 18095N push at 0.9MPa is too powerful, stepping down to a 125mm bore yields 6136N at 0.5MPa. Because the 105mm stroke is relatively short, side-loading is less of a concern, but the substantial 40mm rod diameter still handles high axial stress well. For load-holding without continuous air pressure, select a SAIL or BSAI series cylinder instead of relying on this rear stopper.
To match this exact ISO 15552 footprint, specify a 160mm bore, 105mm stroke, 50mm adjustment range, PT port thread, and the required mounting accessory. This cylinder operates at speeds of 30-500mm/s and uses standard carbon steel rod material without a magnet.
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 SAIJ160X105-50 FAQ
A rear external screw acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 50mm. This creates a usable travel window of 55-105mm, enabling fine-tuning of the retract end-position without changing the cylinder.
At 0.5MPa operating pressure, this 160mm bore cylinder provides a push force of 10053N and a pull force of 9425N. At 0.7MPa, the push force increases to 14074N.
