About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-100S
The AirTAC SAIJ100X700-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 600 to 700 mm, letting you dial back the nominal 700 mm stroke by up to 100 mm. Delivering 7068 N of push force at 0.9 MPa, it handles heavy loads with precision. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The -S magnet option enables position detection with AirTAC CMSE reed or DMSE electronic sensors. It uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 600-700 mm window during machine commissioning to accommodate varying product dimensions without mechanical rework.
Product Size Changeover
Quickly adjust the effective stroke on packaging lines when switching to a different package size, using the 100 mm trim range to set new end positions rapidly.
Heavy-Duty Positioning
Leverage the 7068 N push force at 0.9 MPa to move heavy pallets or fixtures, relying on the SUS304 rod for durability in demanding industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-100S the Right Cylinder?
Choose this 100 mm bore when you need substantial thrust, such as stepping up from a 80 mm bore that provides 4523 N push at 0.9 MPa. The adjustable stroke is ideal for machine setup and product changeover, allowing you to fine-tune the retract end position without swapping the cylinder or adding external stops. At 700 mm, the stroke is long, so an external guide is recommended to manage side loads and prevent rod binding.
To match this ISO 15552 interchangeable cylinder, specify a 100 mm bore, 700 mm nominal stroke, 100 mm adjustment, PT port, SUS304 (B) rod, and -S magnet. Remember that the rear adjuster acts as a travel stop, not a lock; the SAIJ does not hold loads without live air. For true load-holding, consider an external rod lock or the SAIL series.
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 SAIJ100BX700-100S FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 3681 N of pull force. At 0.5 MPa, it delivers 3927 N push and 3681 N pull.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 700 mm nominal stroke by up to 100 mm, providing a usable travel window of 600 to 700 mm. It sets the end position but does not lock the load without live air pressure.
