About the Airtac SAIJ40 Adjustable Cylinder SAIJ40X700-75S
The AirTAC SAIJ40X700-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 625 to 700 mm usable travel window, letting you dial back the end position by up to 75 mm during commissioning. It delivers 879 N of push force at 0.7 MPa and includes a standard magnet for CMSE reed and DMSE electronic sensors.
This 40 mm bore unit uses a PT tapered G1/4 port and a 16 mm carbon steel rod with an M12x1.25 thread. The extruded aluminum barrel provides rigid guidance, but at 700 mm of travel, long unsupported strokes still need an external guide to handle side loads.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40X700-75S Is Used
Machine Changeover
Quickly fine-tune the 625-700 mm end position during product size transitions without swapping cylinders or adding external stops.
Variable End Stops
Adjust the retract distance on the fly to handle varying package lengths on a sorting line.
Setup Calibration
Dial in the exact 700 mm stroke tolerance during machine commissioning to perfect end-of-travel positioning.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40X700-75S the Right Cylinder?
Choose this adjustable model over a fixed SAI when you need variable end stops for product-size changeovers on a line. If you need less force, the 32 mm bore offers 563 N at 0.7 MPa; if you need more, the 50 mm bore provides 1374 N. The rear screw acts only as a travel stop and does not hold the load without live air. For load-holding without pressure, select SAIL or BSAI. To match this ISO 15552 footprint exactly, specify: 40 mm bore, 700 mm stroke, 75 mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounts, and -S magnet.
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 SAIJ40 Adjustable Cylinder SAIJ40X700-75S FAQ
At a 0.7 MPa operating pressure, this 40 mm bore cylinder provides 879 N of push force and 528 N of pull force.
The rear adjuster screw lets you shorten the effective travel from 700 mm down to 625 mm. It functions as a mechanical stop to decelerate the load, not as a lock, and requires live air to hold position.
