About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-50
The AirTAC SAIJ160X80-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 80 mm travel by up to 50 mm. This creates a highly flexible 30-80 mm usable stroke window, perfect for dialing in exact end positions during machine commissioning without swapping hardware. It delivers substantial thrust, generating 9425 N of pull force at 0.5 MPa.
This specific SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this unit is configured without a magnet. The rear screw acts purely as a travel stop to fine-tune deceleration, so it will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-50 Is Used
Heavy Press Tuning
Fine-tune the 30-80 mm stroke window during setup to apply exact clamping force on heavy assemblies without adding external stops.
Product Size Changeover
Quickly adjust the rear stopper on the line when switching between different product heights, leveraging the 50 mm adjustment range.
Actuator Commissioning
Dial in the exact retraction end-position during initial machine build, avoiding the need to physically swap out the cylinder for a different stroke.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-50 the Right Cylinder?
Choose this 160 mm bore when you need heavy push force (10053 N at 0.5 MPa) but require variable end-stops for frequent product changeovers; if your thrust requirements are lower, stepping down to a 125 mm bore provides 5734 N pull force. The SAIJ160X80-50 is dimensionally interchangeable per ISO 15552, utilizing a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Ensure your fluid is filtered to 40 um and operating pressure stays between 0.15 and 1.0 MPa.
Because the nominal stroke is 80 mm, the robust M36x2 rod thread handles high side loads well without needing external guides. Remember that the rear adjuster is a stop, not a lock; for load-holding without live pressure, consider an AirTAC SAIL or BSAI cylinder. This model is configured with PT ports, a SUS420J2 stainless steel rod, and no magnet.
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 SAIJ160AX80-50 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers a maximum push force of 18095 N.
The rear adjuster screw allows you to shorten the 80 mm nominal stroke by up to 50 mm, creating a usable travel window of 30-80 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
