About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-75S
The AirTAC SAIJ100X600-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 600 mm nominal stroke that can be fine-tuned backward by up to 75 mm, yielding a usable travel window of 525 to 600 mm. Belonging to the 100 mm bore class, it delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This model includes a magnetic piston (-S) for position sensing and uses a standard carbon steel rod with an M20x1.5 thread. Because the 600 mm stroke is relatively long, the 25 mm rod diameter provides necessary rigidity, though an external guide is still recommended to manage side loads. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-75S Is Used
Machine Changeover
Dial in the 525-600 mm travel window during product size transitions without physically replacing the cylinder or adding external shims.
Heavy Fixture Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy machining fixtures, using the rear stop to precisely set the final retracted position.
Assembly Line Calibration
Fine-tune the end-of-stroke stopping point on automated assembly lines during initial setup to accommodate mechanical tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-75S the Right Cylinder?
Select this adjustable-stroke cylinder when your application requires precise end-position calibration during commissioning or frequent product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. If you need less force, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa; if your setup demands more power, moving up to a 125 mm bore provides 6136 N.
To match this exact configuration for an ISO 15552 replacement, specify the 100 mm bore, 600 mm stroke, 75 mm adjustment range, PT tapered port thread, and the -S magnet option. Remember that the rear adjuster is a travel stop, not a locking device; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. Given the 600 mm stroke, ensure adequate external guiding to prevent excessive side-loading on the rod.
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 SAIJ100X600-75S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 600 mm nominal length, creating a 525 to 600 mm travel window. It functions as a mechanical stop for end-position tuning and requires live air to hold the load.
