About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-50S
The AirTAC SAIJ80X95-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 2513N push force at 0.5MPa, making it ideal for mid-weight industrial handling. The integrated -S magnet enables position sensing via AirTAC CMSE reed and DMSE electronic switches housed in the dual-side sensor grooves.
With a nominal 95mm stroke and a 50mm adjustment range, this SKU provides a highly flexible usable travel window of 45-95mm. You can fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. It features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-50S Is Used
Machine Changeover
Dial in the exact 45-95mm retract distance during product size transitions without disassembling the tooling or changing the cylinder.
End-Stop Tuning
Use the 50mm rear adjuster to precisely set the final end-position during initial commissioning, absorbing mechanical tolerances instantly.
Corrosive Assembly Lines
Leverage the SUS420J2 stainless steel rod and 2513N thrust for reliable actuation in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-50S the Right Cylinder?
Choose this 80mm bore when 50mm (982N at 0.5MPa) lacks thrust, but 100mm (3927N at 0.5MPa) is physically oversized. The 50mm adjustment capacity is perfect for product-size changeovers on a line, allowing rapid end-stop tuning instead of mechanical rebuilds. The 25mm rod and M20x1.5 thread handle high side-load stresses well.
For any stroke over 300mm, an external guide is mandatory to prevent rod wear, though this 95mm travel is compact enough for self-support. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ cannot hold loads without live air. For true load-holding, select the SAIL (air-released lock) or BSAI (clamp-lock) series. This SAIJ uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2 (omitting FB, CA, CB, CR).
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 SAIJ80AX95-50S FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push thrust and 2268N of pull thrust. It can reach up to 4523N push force at 0.9MPa.
The rear adjuster screw lets you mechanically shorten the 95mm nominal stroke by up to 50mm. This creates a usable travel window of 45-95mm, allowing you to set the exact retract end-position without altering the cylinder mount.
