Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 700mm stroke, G1/2 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 SAIJ100 Adjustable Cylinder SAIJ100X700-100
The AirTAC SAIJ100X700-100 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering a robust 3927N push force at 0.5 MPa. By turning the integrated rear stopper, you can trim the nominal 700mm stroke back by up to 100mm, creating a precise 600-700mm usable travel window for exact end-position tuning during commissioning. This eliminates the need to physically swap out the entire actuator when adapting to a new product format.
It features a 25mm carbon steel piston rod with an M20x1.5 rod thread, providing excellent rigidity and side-load resistance for heavy actuators. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet. The SAIJ series uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR foot and pivot brackets to keep the adjustable rear mechanism compact.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100 Is Used
Variable End-Stop Forming
Dial in the exact 600-700mm travel window during machine setup to accommodate varying material lengths without bolting on external physical stops.
Product Changeover Pusher
Quickly reconfigure the retract end-position on a packaging line when switching to different carton sizes, using the 100mm adjustment range to fine-tune the push distance.
Heavy Fixture Clamping
Secure large workpieces using the 7068N push force at 0.9 MPa, relying on the rear screw to set the precise clamp position while air pressure remains live.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100 the Right Cylinder?
Choose this 100mm bore actuator when your application requires high thrust (3927N push at 0.5 MPa, or 7068N at 0.9 MPa) and on-the-fly stroke adjustment. If you need less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa, whereas moving up to a 125mm bore provides 6136N. Because the nominal stroke is 700mm, an external guide is strongly recommended to prevent excessive side-loading on the long, unsupported 25mm rod. The rear adjuster acts purely as a travel stop and deceleration point, not a lock; for true load-holding without live air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead. To match this ISO 15552 interchangeable cylinder, specify the 100mm bore, 700mm stroke, PT tapered port threads, and your preferred mounting bracket.
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 SAIJ100 Adjustable Cylinder SAIJ100X700-100 FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. If you increase the pressure to 0.9 MPa, the push force rises to 7068N.
The rear adjuster acts as an external stopper that lets you shorten the effective travel from the 700mm nominal stroke by up to 100mm, creating a 600-700mm usable window. It is a travel stop, not a lock, so it will not hold the load without continuous air pressure.
