About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-50S
The AirTAC SAIJ80X700-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 650 to 700 mm. Delivering 2513 N of pull force at 0.5 MPa, it handles substantial loads while allowing precise end-position tuning during commissioning. This model features a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
Because the stroke extends to 700 mm, the 25 mm rod diameter and M20x1.5 rod thread provide necessary rigidity, though an external guide is recommended to manage side loads on long travels. The rear adjuster acts strictly as a mechanical stop for the retract end and does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-50S Is Used
Product Size Changeovers
Quickly adapt machinery to varying product lengths by dialing the retract position back up to 50 mm, eliminating the need for physical spacer modifications.
Machine Setup Tuning
Fine-tune the end-of-stroke position during initial commissioning to achieve perfect alignment without physically remounting the ISO 15552 cylinder.
Variable End Stops
Provide a customizable mechanical stop for diverter arms or pushing mechanisms on conveyors, ensuring precise placement across different batch sizes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-50S the Right Cylinder?
Choose this 80 mm bore when you need more force than a 63 mm cylinder (which provides 1402 N pull at 0.5 MPa) but less bulk than a 100 mm option. The 50 mm adjustment range is ideal for product changeovers on a line, letting you dial in the exact retract distance without swapping cylinders or adding external stops. If your machine requires the load to stay held without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is a stop, not a lock.
This configuration includes PT tapered port threads, a SUS420J2 stainless steel rod, and a -S magnet for use with AirTAC CMSE reed or DMSE electronic solid-state sensors. For any stroke of 300 mm or more, always support the load with an external guide rail to prevent excessive side-loading on the rod.
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 SAIJ80AX700-50S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster allows you to shorten the effective stroke by up to 50 mm, creating a usable travel window of 650 to 700 mm. It acts as a mechanical stop to set the retract position and does not function as a lock to hold the load without air pressure.
