About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-75
The AirTAC SAIJ100X475-75 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 75mm, creating a precise 400-475mm usable travel window. This built-in adjustability allows operators to dial in exact retract end positions during commissioning without swapping out the entire unit.
This model features a standard carbon steel piston rod and a G1/2 port. It retains the standard extruded aluminum barrel with sensor grooves on both sides, though a magnet for CMSE or DMSE switches is not included on this base configuration. The adjustable stopper acts solely as a travel limit and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-75 Is Used
Machine Changeover
Quickly adapt retract end positions for different product sizes on the same line without physically replacing cylinders or adding external mechanical stops.
Commissioning Calibration
Fine-tune the 400-475mm travel window during initial setup to perfectly time machine sequences and avoid hard mechanical crashes.
High-Force Positioning
Leverage the 3927N push force to move heavy fixtures while retaining the flexibility to adjust the stroke by up to 75mm on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-75 the Right Cylinder?
Choose this 100mm bore cylinder when an application requires high thrust (3927N push at 0.5 MPa) alongside variable end-stop positioning. If your setup needs less force, stepping down to an 80mm bore yields 2513N of push force. Because the 475mm stroke is relatively long, an external guide is recommended to prevent excessive side-loading on the rod. The rear adjuster is a stop, not a lock; for load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI model. When matching ISO 15552 dimensions, specify the 100mm bore, 475mm stroke, 75mm adjustment, PT 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 SAIJ100X475-75 FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. It can reach up to 7068N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 75mm, providing a usable travel range of 400-475mm. This mechanism acts as a physical stop to set the end position and does not lock the load without continuous air pressure.
