About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-30S
The AirTAC SAIJ100X200-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 170 to 200 mm. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers a robust 3927 N push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This model includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the dual sensor grooves on the extruded aluminum barrel. The rear stopper allows precise end-position tuning during commissioning without adding external stops, though it acts only as a travel limit and does not hold the load without live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-30S Is Used
Changeover Calibration
Dial in the 170-200 mm travel window during product size changeovers to set new retract stops without swapping hardware.
Heavy Forming Stops
Leverage the 3927 N push force at 0.5 MPa to drive forming tools, using the rear screw to fine-tune the bottoming position.
Machine Setup Tuning
Trim up to 30 mm off the nominal stroke during initial commissioning to perfectly sync multi-axis machine timing.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-30S the Right Cylinder?
Select this 100 mm bore when an application requires higher thrust than the 80 mm version (2513 N push at 0.5 MPa) but does not need the massive output of a 125 mm cylinder. The 30 mm adjustment range is ideal for fine-tuning the retract end position during machine setup or product changeover, offering flexibility that a fixed-stroke SAI cylinder cannot provide.
For an exact ISO 15552 replacement match, verify the 200 mm stroke, 30 mm adjustment, PT port threads, and the -S magnet option. Because the stroke is 200 mm, side-load stress is moderate, but ensure external guiding is used if the load is heavy or off-center. If true load-holding is required without continuous air pressure, consider an AirTAC SAIL or BSAI 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 SAIJ100BX200-30S 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 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 200 mm nominal stroke by up to 30 mm, creating a 170-200 mm travel window. It only sets the end position and does not lock the load without live air pressure.
