About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-20S
The AirTAC SAIJ80X60-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 40 to 60 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod (code A) and a built-in magnet for position sensing.
This adjustable-stroke design allows precise end-position tuning during commissioning without swapping hardware. It features PT tapered ports and standard variable air cushions at both ends, but the rear adjuster acts only as a travel stop, not a load lock.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-20S Is Used
Machine Setup Tuning
Fine-tune the 40-60 mm travel end position precisely during commissioning to accommodate slight mechanical variations without machining new spacers.
Product Changeover
Quickly adjust the stroke length on packaging lines when handling different product sizes, using the rear screw to set the new retract stop.
Variable End Stops
Achieve exact clamping or positioning depths on short-stroke tooling where a fixed 60 mm cylinder would require manual shimming.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-20S the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm bore (which provides 1559 N push at 0.5 MPa), but without the full bulk of a 100 mm cylinder. The 20 mm adjustment range is ideal for dialing in exact end stops during machine setup or product changeovers, avoiding the need for external stops.
For exact ISO 15552 replacement matching, verify the 80 mm bore, 60 mm nominal stroke, 20 mm adjustment range, PT port threads, and the -S magnet option. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If the machine requires true load holding without live air pressure, use an external rod lock or consider the SAIL or BSAI series instead.
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 SAIJ80 Adjustable Cylinder SAIJ80AX60-20S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. It can reach up to 4523 N push force at 0.9 MPa.
The rear adjuster screw allows you to trim the nominal 60 mm stroke back by up to 20 mm, creating a usable travel window of 40 to 60 mm. The adjuster functions as a mechanical stop for end-position tuning and does not lock the load without live air.
