About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-10S
The AirTAC SAIJ100X30-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927N push force at 0.5 MPa. It features a carbon steel piston rod with an M20x1.5 thread and PT tapered port threads. Because this specific SKU includes the -S magnet option, it is fully compatible with AirTAC CMSE reed and DMSE solid-state sensors mounted into the dual-side barrel grooves.
With a nominal 30mm stroke and a 10mm adjustment range, the usable travel window spans from 20 to 30mm. This built-in rear stopper allows for highly precise end-position tuning during commissioning without swapping hardware. The adjuster acts solely as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-10S Is Used
Fixture Positioning
Dial in the exact 20-30mm clamping position during machine setup to accommodate varying workpiece sizes without adding external stopper blocks.
Changeover Tuning
Rapidly adjust the stroke end-point during product line changeovers to achieve precise end-of-travel positions for new components.
Short-Stroke Pressing
Apply up to 3927N of force for short pressing or seating operations, using the rear screw to fine-tune the bottoming depth accurately.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-10S the Right Cylinder?
Selecting this 100mm bore adjustable model makes sense when an application requires heavy force but exact end-of-stroke positioning varies slightly between fixtures, as the 10mm trim window compensates for mechanical tolerances at setup. If your application requires less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa, while a 125mm bore provides 6136N for heavier loads. To achieve a direct ISO 15552 replacement, match the 100mm bore, 30mm stroke, 10mm adjuster, PT ports, and the -S magnet requirement.
Although the stroke is short, the M20x1.5 rod provides substantial rigidity. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR variants found in other lines.
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 SAIJ100X30-10S FAQ
At a standard 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. It can reach up to 5497N push force at 0.7 MPa.
The nominal stroke is 30mm, but the rear adjuster allows you to trim the stroke by up to 10mm. This creates a usable travel window of 20 to 30mm for fine-tuning the end position.
