About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-30S
The AirTAC SAIJ80X700-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 670 to 700 mm, allowing you to dial back the end position by up to 30 mm during commissioning without adding external stops. It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it suitable for heavy actuation.
This SKU includes a SUS420J2 stainless steel rod for improved corrosion resistance and a magnet for position sensing. It works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the G3/8 PT ports manage airflow for its 30-800 mm/s speed range.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-30S Is Used
Machine Changeover
Fine-tune the 670-700 mm retract end-stop on the fly when switching production runs, avoiding mechanical cylinder swaps.
Variable End Positioning
Dial in the exact 30 mm trim window to align heavy product pushers without repositioning the entire ISO 15552 mounting block.
Heavy Assembly Press
Leverage 2513 N of thrust at 0.5 MPa to seat components, using the rear screw to set precise final positioning limits.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-30S the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) lacks the thrust for your dynamic load, but a 100 mm bore (3927 N) would be excessive. The adjustable stroke is ideal for product changeovers, letting you fine-tune the retract end without swapping the cylinder. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, select the SAIL or BSAI series instead.
At 700 mm of travel, the M20x1.5 rod and 36 mm cushions handle significant kinetic energy, but the long unsupported stroke requires an external guide to prevent rod side-loading damage. As a dimensionally interchangeable ISO 15552 cylinder, it uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.

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 SAIJ80AX700-30S FAQ
The rear adjuster screw lets you shorten the nominal 700 mm stroke by up to 30 mm, creating a 670-700 mm travel window. It acts as a mechanical stop and does not lock the load without continuous air pressure.
At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa operating pressure, it generates 4523 N of push force.
