Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-50
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-50
The AirTAC SAIJ80X700-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 3518N of push force at 0.7 MPa and provides a usable travel window of 650 to 700 mm, letting you dial back the nominal 700 mm stroke by up to 50 mm during commissioning. A 25 mm piston rod with an M20x1.5 thread handles high side loads, while the SUS420J2 stainless steel rod material adds corrosion resistance for harsher industrial environments.
This model uses PT tapered G3/8 ports and variable air cushions at both ends to manage deceleration. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops; it does not hold the load without live air. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-50 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 650 and 700 mm on the fly, perfect for machinery that processes multiple product lengths without changing cylinders.
Commissioning Fine-Tuning
Use the 50 mm rear adjustment screw to trim the final end position during machine setup, avoiding the need to bolt on external physical stops.
Long-Stroke Material Handling
Leverage the 700 mm travel and 3518N push force to move heavy pallets or pusher assemblies, fine-tuning the discharge point as needed.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-50 the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires substantial thrust—stepping down to a 63 mm bore yields 2182N at 0.7 MPa, while stepping up to a 100 mm bore provides 5497N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, negating the need to physically swap out a fixed-stroke SAI cylinder.
Because the 700 mm stroke is quite long, an external guide is recommended to prevent rod sag and absorb lateral forces. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR options. Operating speed ranges from 30 to 800 mm/s.

- ✓ 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 SAIJ80AX700-50 FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder generates 3518N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective stroke from 700 mm down to 650 mm, providing a 50 mm tuning window. It functions as a mechanical travel stop and does not lock the load without continuous air pressure.
