About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-10S
The AirTAC SAIJ100X225-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This yields a usable window of 215 to 225 mm, letting you dial in the exact retract end-position during commissioning without adding external stops. As a non-standard stroke made-to-order unit, it provides a tailored travel length for specific machine layouts.
Delivering 3927 N of push force at 0.5 MPa (and up to 7068 N at 0.9 MPa), it is built for heavy payloads. This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE reed and DMSE electronic sensors. It features a G1/2 port, M20x1.5 rod thread, and air cushions at both ends to decelerate loads smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-10S Is Used
Machine Commissioning
Fine-tune the 215-225 mm retract position during initial setup to perfectly align stops without machining new mounting plates.
Product Changeover
Quickly adjust the end-stop by up to 10 mm when running a slightly different product size on the same line.
Heavy Material Handling
Leverage the 3927 N push force at 0.5 MPa to move heavy workpieces while using the rear screw to tweak the rest position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-10S the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (providing 2513 N push at 0.5 MPa) is insufficient for your load, but you want to avoid stepping up to a 125 mm cylinder. The 10 mm rear adjuster is ideal for product changeovers where a precise end-of-stroke position must be tweaked quickly. Because the nominal stroke is 225 mm, mount an external guide to support the rod and prevent excessive side-load wear on the seals.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 225 mm stroke, 10 mm adjustment, G1/2 PT ports, and the -S magnet requirement. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For true load-holding, consider an AirTAC SAIL or BSAI cylinder. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB and CA options.
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 SAIJ100BX225-10S 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 0.9 MPa, the push force increases to 7068 N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 225 mm nominal stroke by up to 10 mm. This creates a usable travel window of 215 to 225 mm. It is a stop, not a lock, and requires live air to hold position.
