About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-50
The AirTAC SAIJ100X700-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a generous 7068N of push force at 0.9 MPa and a usable travel window of 650 to 700 mm. The integrated rear stopper lets you dial back the stroke by up to 50 mm during commissioning, removing the need to bolt on external physical stops.
This 100mm bore unit uses a G1/2 port and a robust 25mm carbon steel rod. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Keep in mind the rear adjuster functions purely as a travel stop to set end positions and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-50 Is Used
Machine Changeover
Quickly fine-tune the 650-700 mm retract position when switching between different product sizes on a packaging line, using the rear screw instead of external stopper blocks.
End-Stop Calibration
Achieve exact positioning during machine commissioning by trimming up to 50 mm off the stroke, allowing perfect alignment without machining new mounting plates.
Material Push-Off
Leverage the 7068N push force at 0.9 MPa to reliably eject heavy workpieces, while retaining the flexibility to adjust the ejection distance as needed.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-50 the Right Cylinder?
Choose this adjustable model when your machine setup requires precise end-position tuning across a 650-700 mm window, or when accommodating product changeovers without physically swapping cylinders. If you need less force, stepping down to the 80mm bore yields 4523N at 0.9 MPa. For heavier loads, the 125mm bore provides 11045N.
When matching this for an ISO 15552 replacement, verify the 100mm bore, 700mm nominal stroke, 50mm adjustment range, G1/2 PT port, and your required mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR. Because the stroke is 700mm, the long unsupported piston rod is susceptible to side-loading; always use an external guide to prevent premature wear. If your application requires true load-holding without continuous air pressure, use an SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
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 SAIJ100X700-50 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 50 mm. This creates a usable travel window of 650 to 700 mm, which is set during commissioning without needing to remove or replace the cylinder.
At an operating pressure of 0.9 MPa, the SAIJ100X700-50 provides a push force of 7068N and a pull force of 3681N. It operates at speeds between 30 and 800 mm/s.
