Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 700mm stroke, G1/8 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 Adjustable Cylinder SAIJ32 SAIJ32AX700-30
The AirTAC SAIJ32X700-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 700 mm stroke by up to 30 mm. This yields a usable travel window of 670-700 mm, perfect for fine-tuning the retract end position during machine commissioning without swapping out the barrel. It features a SUS420J2 stainless steel rod and PT tapered ports.
Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, this 32 mm bore unit relies on its 12 mm rod and M10x1.25 thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. The rear screw acts purely as a mechanical stop to set the travel end, meaning it will not hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-30 Is Used
Machine Commissioning
Dial in the exact retract position within the 670-700 mm window during initial setup, avoiding the need to machine custom spacers.
Product Changeover
Quickly adjust the end-stop by up to 30 mm when running a different product size on the line, minimizing changeover downtime.
Transfer Positioning
Set precise retract stops for a 32 mm bore transfer mechanism providing 402 N of push force at 0.5 MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-30 the Right Cylinder?
Choose this adjustable SAIJ variant over a fixed-stroke SAI when your application requires variable end-stops or frequent product-size changeovers, allowing precise repositioning without adding external stops. If your setup demands higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 700 mm stroke is relatively long for the 32 mm bore, the 12 mm rod carries a finite side-load capacity; you must use an external guide to prevent rod binding and premature seal wear.
For an exact ISO 15552 replacement match, verify the 32 mm bore, 700 mm stroke, 30 mm adjustment range, PT port thread, and the absence of a magnet (no -S). Note that this cylinder supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without live pressure, consider the SAIL or BSAI series instead.
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 Adjustable Cylinder SAIJ32 SAIJ32AX700-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the nominal 700 mm down to 670 mm. This mechanical stop fine-tunes the retract end position but does not lock the load; live air pressure is required to hold position.
