About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX95-40
The AirTAC SAIJ50X95-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 982N push force at 0.5MPa and uses a 20mm diameter carbon steel rod, but this specific configuration upgrades the rod material to SUS420J2 stainless steel (code A) for superior corrosion resistance. The PT tapered port threads ensure a tight, reliable pneumatic connection.
With a 95mm nominal stroke and a 40mm adjustment range, the usable travel window can be fine-tuned anywhere from 55mm to 95mm. This built-in adjustability allows operators to dial in exact end-positions during commissioning without swapping out the entire cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX95-40 Is Used
Machine Commissioning
Dial in the exact 55-95mm travel distance during initial setup without machining custom spacers or changing the cylinder.
Product Changeover
Quickly adapt the end-stop position on a packaging line when switching between different carton sizes.
Variable End-Stop Forming
Adjust the stroke on the fly for light pressing or forming tasks that require slight positional tweaks based on material thickness.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX95-40 the Right Cylinder?
Choose this 50mm bore model when your application requires the 982N thrust at 0.5MPa (or 1374N at 0.7MPa) but demands precise variable end-stops. If your process needs less force, step down to a 40mm bore (628N at 0.5MPa); for heavier loads, step up to a 63mm bore (1559N at 0.5MPa). The rear adjuster acts purely as a travel stop to decelerate the piston—it does not hold the load without live air pressure. For dead-stop load holding, consider an AirTAC SAIL or BSAI cylinder.
This cylinder is dimensionally interchangeable per ISO 15552. To match this exact configuration, specify a 50mm bore, 95mm stroke, 40mm adjustment, PT ports, SUS420J2 rod material, and no magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets found on some other series.

- ✓ 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 SAIJ50 Adjustable Cylinder SAIJ50AX95-40 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 40mm. This creates a usable travel window of 55-95mm, allowing you to fine-tune the retract end-position without adding external stoppers.
At 0.5MPa operating pressure, it provides 982N of push force and 825N of pull force. At 0.7MPa, the push force increases to 1374N.
