About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-50
The AirTAC SAIJ160X950-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 950 mm nominal stroke to a 900 mm minimum. Delivering massive thrust, it provides 14074N of push force and 9425N of pull force at 0.7 MPa. The piston rod is built from SUS420J2 stainless steel, offering high resistance to corrosion and improved durability in harsh environments.
Equipped with a G3/4 PT tapered port, this 160 mm bore unit relies on adjustable air cushions at both ends to decelerate the heavy load over a 50 mm cushioning length. The rear stopper mechanism lets you dial in the exact retract position during commissioning or product changeover without swapping out the entire barrel. Note that this adjuster acts purely as a travel stop; it does not lock the load or hold position without continuous air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-50 Is Used
Heavy Press Tuning
Dial in the exact 900 to 950 mm retract position during machine commissioning to ensure perfect pressing depth without machining custom spacers.
Variable Product Changeover
Quickly adjust the end-stop distance on an automated line when switching between different large-format product sizes.
Automated Heavy Assembly
Leverage the 14074N push force to move heavy components into place while using the rear screw to fine-tune the final resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-50 the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high force combined with variable end-position tuning. If your setup requires slightly less force, stepping down to a 100 mm bore yields 5497N of push at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991N. The integrated 50 mm adjustment window is ideal for machinery that processes varying product sizes, allowing operators to reposition the retract stop on the fly instead of installing external hard stops.
Because the 950 mm stroke is quite long, the 40 mm diameter rod will experience bending stress under high side loads; an external guide rail is strongly recommended to prevent premature seal wear. This unit is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Since no magnet is specified, it will not support CMSE or DMSE sensors without modification.
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 SAIJ160AX950-50 FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074N of push force and 9425N of pull force. It can deliver a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stopper, allowing you to shorten the effective travel from the 950 mm nominal stroke down to 900 mm. This creates a 50 mm tuning window for precise end-positioning without needing to replace the cylinder.
