About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-30
The AirTAC SAIJ160X115-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 85-115 mm, allowing you to dial back the 115 mm nominal stroke by up to 30 mm during commissioning. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
This adjustable model uses a standard carbon steel piston rod with an M36x2 thread, paired with a PT tapered port. The extruded aluminum barrel includes sensor grooves on both sides for positioning switches. The rear adjuster acts purely as a mechanical stop to set the retract end position, meaning it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-30 Is Used
Heavy Press Tuning
Dial in the exact 85-115 mm retract distance during machine setup to accommodate varying material thicknesses in a heavy-duty press without external spacers.
Product Changeover
Rapidly adjust the end-stop position on an assembly line when switching between product sizes, using the 30 mm adjustment range to fine-tune the stroke.
End-Stop Calibration
Set precise retract positions during commissioning of large automated machinery, leveraging the built-in stopper instead of machining custom external stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-30 the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires heavy force combined with precise end-position tuning. If you need less thrust, stepping down to the 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas moving up to the 200 mm bore provides 15080 N. The SAIJ160X115-30 is selected over a fixed-stroke SAI cylinder when you need a variable end-stop for product changeovers without swapping the cylinder or adding external stops.
For load-holding without continuous air pressure, this cylinder is insufficient because the adjuster and air cushions are not locks; you would need to specify an SAIL or BSAI series cylinder instead. When integrating this model, note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles. The operating speed for this bore is 30-500 mm/s.
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 SAIJ160X115-30 FAQ
This 160 mm bore cylinder generates 10053 N of pull force and 14074 N of push force at 0.5 MPa. At 0.9 MPa, the push force reaches 18095 N.
The nominal stroke is 115 mm, but the rear adjuster allows you to shorten the effective stroke by up to 30 mm, creating an adjustable travel window of 85-115 mm.
