About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-100S
The AirTAC SAIJ160X180-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 80 to 180 mm. Fitted with a carbon steel rod and a -S magnet for electronic DMSE or reed CMSE sensors, it handles heavy loads with 14074N of pull force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This 160 mm bore model uses PT tapered ports and offers a maximum adjustment range of 100 mm, allowing you to dial back the stroke for exact end-position tuning without swapping hardware. It supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and relies on 50 mm air cushions at both ends to decelerate the payload smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-100S Is Used
Heavy Press Tuning
Dial back the 180 mm stroke by up to 100 mm to set exact pressing depth for different material thicknesses without changing the cylinder.
Machine Changeover
Quickly adjust the retract end-position during product family transitions on a line, saving commissioning time over fixed-stroke alternatives.
Variable End Stops
Use the wide 80-180 mm travel window to accommodate varying part sizes in automated heavy-assembly equipment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-100S the Right Cylinder?
Choose this 160 mm bore when you need immense thrust—up to 18095N pull at 0.9 MPa—surpassing the 125 mm bore (5734N pull at 0.5 MPa). The 100 mm adjustment window is perfect for product changeovers, letting you fine-tune the retract end-stop on the fly instead of machining external stops or buying a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a travel stop; it will not hold the load without live air pressure. For true load-holding, select a SAIL or BSAI cylinder, or use an external rod lock.
As a dimensionally interchangeable ISO 15552 profile cylinder, it replaces equivalent units using the exact bore, 180 mm stroke, 100 mm adjustment, PT G3/4 ports, and -S magnet specifications. Because the stroke is 180 mm, side-load risks are moderate, but you should still guide long unsupported loads to protect the 40 mm carbon steel rod and M36x2 thread.
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 SAIJ160X180-100S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a pull force of 18095N and a push force of 18095N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw lets you shorten the nominal 180 mm stroke by up to 100 mm, creating a usable travel window of 80 to 180 mm. This stopper only sets the end position and does not lock the load without live air.
