About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-50
The AirTAC SAIJ100X475-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N of push force at 0.5 MPa and features a 475mm nominal stroke that can be fine-tuned down by up to 50mm, creating a precise 425-475mm usable travel window. This built-in adjustability allows you to dial in the retract end position during commissioning without swapping out the entire unit.
This bore size utilizes a G1/2 port and a 25mm carbon steel rod with an M20x1.5 thread, providing substantial rigidity for heavy loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Mounting options include the standard SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-50 Is Used
Product Changeovers
Quickly shift the retract end position by up to 50mm when running different product sizes on the same line, eliminating the need to physically swap cylinders or reposition external hard stops.
Heavy Press Fitting
Leverage the 3927N push force at 0.5 MPa to seat large components, using the fine stroke adjustment to perfectly tune the insertion depth without over-traveling.
Long-Stroke Material Handling
Move heavy payloads along a 425-475mm travel path, relying on the 25mm rod and M20x1.5 thread to handle high mechanical stress during transfer operations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-50 the Right Cylinder?
Choose this 100mm bore cylinder when your application requires high thrust—such as the 3927N push force at 0.5 MPa—and exact end-position tuning. If your force requirements are lower, stepping down to an 80mm bore yields 2513N of push force, while stepping up to a 125mm bore provides 6136N. The adjustable stroke is ideal for product changeovers on a line, allowing you to shift the end stop by up to 50mm without adding external stops. To replace an ISO 15552 cylinder, match the 100mm bore, 475mm stroke, PT port thread, and mounting style. Note that this model does not include a magnet for sensors; add an -S suffix if CMSE or DMSE switches are needed.
Because the 475mm stroke is relatively long, the 25mm rod will experience increased bending moments under heavy side loads; an external guide rail is recommended to prevent premature seal wear. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air. For load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder.

- ✓ 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 SAIJ100X475-50 FAQ
At a standard operating pressure of 0.5 MPa, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from its 475mm nominal length down to 425mm. It allows precise end-position tuning during setup but does not lock the load without continuous air pressure.
