About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-30
The AirTAC SAIJ80X95-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. This creates a usable stroke window of 65 to 95 mm, letting you dial in the exact end position at commissioning without swapping out the hardware. Delivering 2268 N of pull force at 0.5 MPa, it handles demanding positioning tasks with ease.
This model uses a SUS420J2 stainless steel rod for enhanced durability against minor moisture and a PT tapered port thread for a tight pneumatic seal. The extruded aluminum barrel features sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if you add a magnet later. It supports a standard speed range of 30-800 mm/s and uses the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-30 Is Used
Product Changeover Dials
Quickly adjust the retract end position within the 65-95 mm window when switching between part sizes on a machining line, eliminating the need to physically swap cylinders or add external spacers.
End-Stop Commissioning
Fine-tune the final resting position of your tooling during initial machine setup, ensuring perfect alignment and absorbing kinetic energy using the integrated variable air cushions at both ends.
Heavy-Duty Positioning
Leverage the 2268 N pull force at 0.5 MPa to move and position heavy jigs or fixtures, using the SUS420J2 stainless steel rod to withstand industrial plant environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-30 the Right Cylinder?
Choose this 80 mm bore when your application requires more thrust than a 63 mm cylinder (which provides 1402 N pull at 0.5 MPa) but does not need the full 3681 N pull force of a 100 mm unit. The adjustable stroke is ideal for machine setups that undergo frequent product changeovers, allowing the retract end-stop to be fine-tuned on the fly. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ cannot hold a load without live air pressure, so for fail-safe load holding you should consider an external rod lock or the AirTAC SAIL series.
To replace this ISO 15552 cylinder, match the 80 mm bore, 95 mm nominal stroke, 30 mm adjustment range, PT port thread, and your required mounting bracket. Because the 95 mm stroke is relatively short, side-loading stress is minimal, but you should still ensure the rod thread (M20x1.5) is properly aligned with your load coupling to prevent binding.
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 SAIJ80AX95-30 FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. The maximum thrust is 513 kgf at 1.0 MPa.
The rear external adjuster screw allows you to shorten the 95 mm nominal stroke by up to 30 mm, creating a usable travel window of 65 to 95 mm. This mechanism acts as a physical stop to set the end position and does not lock the load without live air pressure.
