About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X280-75S
The AirTAC SAIJ100X280-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 280 mm stroke that can be fine-tuned down by up to 75 mm, creating a usable travel window of 205-280 mm. Delivering 5497 N of push force at 0.7 MPa, it is built to handle heavy loads with precision.
This unit includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the extruded aluminum barrel's dual sensor grooves. The standard carbon steel rod features an M20x1.5 thread, while the rear PT tapered port and adjustable stopper allow for exact end-position calibration without adding external physical stops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X280-75S Is Used
Product Changeover
Dial the rear stopper back by 75 mm to instantly accommodate shorter parts on the same conveyor line without swapping cylinders.
Machine Setup
Fine-tune the end-of-stroke position during commissioning to perfect pressing depth, avoiding the need for external mechanical stops.
Variable End Stops
Use the 205-280 mm travel window to adjust clamping distances on the fly for custom or multi-size fabrication runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X280-75S the Right Cylinder?
Choose this 100 mm bore when 7068 N of thrust at 0.9 MPa is required, stepping down to an 80 mm bore if you only need 4523 N. The 75 mm adjustment range is perfect for production lines running mixed product sizes, allowing rapid changeover by dialing in the exact retract distance. Since the stroke is 280 mm, an external guide is recommended to prevent excessive side-load wear on the M20 rod.
The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. To match this ISO 15552 cylinder, specify a 100 mm bore, 280 mm stroke, 75 mm adjustment, PT port thread, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100X280-75S FAQ
The rear adjusting screw acts as a stopper that lets you shorten the effective stroke by up to 75 mm. This gives the 280 mm nominal stroke a usable travel window of 205-280 mm, which is set mechanically at commissioning.
At a 0.7 MPa operating pressure, it provides 5497 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 7068 N.
