About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-100
The AirTAC SAIJ100X160-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 60 to 160 mm, allowing you to dial back the nominal 160 mm stroke by up to 100 mm during commissioning. This bore delivers robust thrust, generating 7068 N of push force at 0.9 MPa.
The piston rod is constructed from SUS420J2 stainless steel (material code A), offering enhanced corrosion resistance compared to standard carbon steel. The rear adjuster acts purely as a mechanical stop to set the end position; it does not lock or hold the load without live air pressure. For load-holding applications, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-100 Is Used
Variable End-Stop Forming
Dial in the exact 60 to 160 mm travel window during press setup to accommodate different material thicknesses without changing the cylinder.
Machine Changeover
Quickly fine-tune the retract end-position by up to 100 mm when switching production runs, avoiding external stopper hardware.
Heavy-Duty Positioning
Leverage the 7068 N push force at 0.9 MPa to move heavy pallets or tooling, relying on the rear screw for precise end-of-stroke tuning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-100 the Right Cylinder?
Choose this 100 mm bore when your application requires heavy thrust—stepping down to an 80 mm bore reduces the push force to 4523 N at 0.9 MPa. The adjustable stroke is ideal for machines that require variable end-stops or frequent product-size changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder. Since the nominal stroke is 160 mm, an external guide is recommended if the load is heavy or subject to high side-loading forces.
When replacing an ISO 15552 cylinder, verify the 100 mm bore, 160 mm stroke, 100 mm adjustment range, PT tapered port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This SKU does not include a magnet, so CMSE and DMSE sensors cannot be used for position detection.
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 SAIJ100 Adjustable Cylinder SAIJ100AX160-100 FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 160 mm down to 60 mm, creating a 100 mm adjustable window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At 0.9 MPa, this 100 mm bore cylinder provides a push force of 7068 N and a pull force of 3681 N. The maximum force at 1.0 MPa is 801 kgf.
