About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-30S
The AirTAC SAIJ100X800-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N push force at 0.5MPa and features a 30mm adjustment range, creating a precise 770-800mm usable travel window for fine-tuning the retract end position during commissioning.
This extruded aluminum profile cylinder includes a magnet for position sensing and uses a G1/2 PT tapered port. The 25mm carbon steel rod and M20x1.5 thread provide excellent side-load resilience, though the lengthy 800mm stroke still necessitates an external guide to prevent rod deflection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-30S Is Used
Variable End-Stop Configuration
Dial in the exact retract position within the 770-800mm window during machine setup, avoiding the need to add external mechanical stops.
Product Size Changeover
Quickly adapt a long-stroke conveyor sorting arm to handle different package lengths by adjusting the rear stopper on the fly.
Long-Stroke Positioning
Leverage the 3927N thrust at 0.5MPa to move heavy pallets, using the 30mm adjuster to fine-tune the final resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-30S the Right Cylinder?
Select this adjustable-stroke model over a fixed SAI cylinder when your application requires variable end-stops or product-size changeovers without swapping the entire actuator. If you need less force, stepping down to an 80mm bore yields 2513N at 0.5MPa; stepping up to a 125mm bore provides 6136N. For direct ISO 15552 replacement matching, specify the 100mm bore, 800mm stroke, 30mm adjustment, PT port thread, and the -S magnet option.
Because the stroke is 800mm, ensure adequate external guiding to support the load. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold its position without live air. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder 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 SAIJ100 Adjustable Cylinder SAIJ100X800-30S FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the nominal 800mm stroke by up to 30mm, providing a usable travel window of 770-800mm. This stopper only sets the end position and does not lock the load without live air pressure.
