About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-50S
The AirTAC SAIJ100X90-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. Because this specific SKU carries a 50mm adjustment code on a 90mm nominal stroke, you gain a usable travel window of 40-90mm. This wide tuning band is ideal for dialing in exact end positions during machine commissioning without swapping hardware.
It features a carbon steel piston rod, PT tapered port threads, and a built-in magnet (-S) for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper simply trims the retract stroke—it is not a locking device.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-50S Is Used
Product Changeovers
Quickly reconfigure the 40-90mm travel window on packaging lines when handling different carton sizes without changing the cylinder.
End-Position Tuning
Fine-tune the retract stroke during machine setup to achieve exact material contact points, preventing crushing or under-travel.
Heavy Forming Stops
Leverage the 7068N push force at 0.9MPa to drive heavy press operations while using the rear screw to set precise bottoming depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-50S the Right Cylinder?
Choose this 100mm bore when you need heavy thrust but require significant travel flexibility on the fly. If 3927N at 0.5MPa is excessive, stepping down to an 80mm bore yields 2513N; if you need more power, a 125mm bore provides 6136N. The 50mm adjustment range makes this SKU superior to a fixed SAI cylinder for product-size changeovers. Remember that the adjuster acts only as a travel stop, so for load-holding without live air, select an external rod lock or a SAIL cylinder. To replace an ISO 15552 unit, match the 100mm bore, 90mm stroke, G1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SAIJ100X90-50S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50mm. With the 90mm nominal stroke, this creates a usable travel window of 40-90mm, allowing precise end-position tuning at commissioning without adding external stops.
At 0.5MPa, it provides 3927N of push force and 3681N of pull force. At 0.9MPa, the push force increases to 7068N.
