About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-30S
The AirTAC SAIJ100X290-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 290 mm nominal stroke that can be dialed back by up to 30 mm, creating a precise 260-290 mm usable travel window for fine-tuning end positions during commissioning. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa and utilizes a carbon steel piston rod with an M20x1.5 thread.
This adjustable-stroke model includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which seat cleanly into the dual sensor grooves on the extruded aluminum barrel. The rear adjuster acts strictly as a travel stop to set the retract position and relies on the integrated air cushions for end-of-stroke deceleration. It supports a standard mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-30S Is Used
Product Changeovers
Dial in the 260-290 mm travel window during format size changes on a packaging line, using the rear screw to set new retract endpoints rapidly without swapping hardware.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to perfectly mate the 100 mm bore tooling against varying workpiece heights.
Variable End Stops
Provide adaptable stopping points for heavy actuators requiring 3927 N of push force, relying on the built-in air cushions to decelerate the load smoothly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-30S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust—3927 N push at 0.5 MPa—along with variable end-stop positioning. If you need to step down force, the 80 mm bore provides 2513 N push at 0.5 MPa; stepping up to 125 mm yields 6136 N. The adjustable stroke is selected over a fixed SAI model when you need to trim the retract position on the fly during product changeovers without adding external stops.
Because the 290 mm stroke exceeds 300 mm when fully extended, ensure you provide an external guide to support the load and mitigate side-loading on the M20x1.5 rod. This SAIJ100X290-30-S variant uses PT tapered port threads and includes a magnet for position sensing. Note that the rear adjuster is a stop, not a lock; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100X290-30S FAQ
At a 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 allows you to shorten the 290 mm nominal stroke by up to 30 mm, providing a usable travel window of 260-290 mm. The adjuster functions as a mechanical stop and does not lock the load without continuous air pressure.
