About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-50
The AirTAC SAIJ160X115-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, generating 14074N of push force at 0.7 MPa. The built-in rear adjusting screw allows you to fine-tune the effective travel down to a 65 mm minimum, creating a precise 65-115 mm usable window without swapping out the hardware.
Equipped with a robust 40 mm carbon steel rod and a G3/4 PT tapered port, this 160 mm bore unit handles heavy loads effectively. The extruded aluminum barrel includes dual sensor grooves, and variable air cushions at both ends manage deceleration. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-50 Is Used
Heavy Press Changeover
Dial in the 65-115 mm travel window during product changeovers to accommodate varying material thicknesses without repositioning the cylinder.
Precision End-Stop Tuning
Fine-tune the final retract position at machine commissioning using the rear screw, ensuring exact alignment for high-force assembly tasks.
Variable Forming Depth
Adjust the effective stroke on the fly for heavy-duty forming or bending operations that require different depths across multiple production runs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-50 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires heavy force combined with variable end-position tuning. If you need slightly less thrust, stepping down to a 125 mm bore yields 8590N of push force at 0.5 MPa. Choose the SAIJ adjustable-stroke series over a fixed SAI model when you need to accommodate product-size changes on a line without adding external stops. For load-holding without live pressure, use an external rod lock or pilot-operated check valve, as the adjuster is not a brake.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 115 mm stroke, 50 mm adjustment range, G3/4 PT port, and the standard carbon steel rod. This model omits the FB, CA, CB, and CR mounting accessories, utilizing a reduced set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 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 SAIJ160X115-50 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074N of push force and 9425N of pull force. It reaches a maximum thrust of 18095N at 0.9 MPa.
The rear adjuster screw lets you shorten the 115 mm nominal stroke by up to 50 mm, providing a usable travel window of 65 to 115 mm. This stopper only limits travel and does not lock the load without live air pressure.
