About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX700-10
The AirTAC SAIJ40X700-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel to a 690-700 mm window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This specific SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, and utilizes PT tapered port threads. The rear adjuster functions strictly as a mechanical stop to dial in the end position during commissioning; it is not a locking device and will not hold the load without continuous live air pressure.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX700-10 Is Used
Machine Setup & Commissioning
Dial in the exact retract end-position within the 690-700 mm window during initial machine commissioning without machining custom spacers.
Product Size Changeovers
Quickly adapt the retract stroke distance up to 10 mm on packaging lines when handling slightly different product dimensions.
Long-Stroke Push Positioning
Utilize the 700 mm travel for extending push actions while relying on the rear stopper to absorb final end-impact fine-tuning.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX700-10 the Right Cylinder?
The 10 mm adjustment range is ideal for product changeovers or fine-tuning the retract end position without adding external stopper blocks or physically swapping the cylinder for a fixed-stroke SAI model.
Because the nominal stroke is 700 mm, the M12x1.25 rod and piston assembly will experience leverage forces during travel; an external guide is recommended to prevent side-loading damage. For position holding without live air, this cylinder cannot lock the load—consider an AirTAC SAIL or BSAI series, or an external pilot-operated check valve. To match this ISO 15552 replacement exactly, specify: 40 mm bore, 700 mm stroke, 10 mm adjustment, PT port, no magnet, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ40AX700-10 FAQ
At 0.7 MPa, the push force increases to 879 N.
An external adjusting screw at the rear of the cylinder acts as a mechanical stop, allowing you to shorten the effective stroke from 700 mm down to 690 mm. It sets the travel end-point but does not lock or hold the load without live air pressure.
