About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-30S
The AirTAC SAIJ100X475-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927N of push force at 0.5 MPa and features a built-in magnet for position sensing. The rear stopper screw allows you to trim the effective travel, creating a 445-475mm usable stroke window from the 475mm nominal length without adding external stops.
This adjustable-stroke design enables fine end-position tuning during commissioning or product changeover. It features a robust 25mm carbon steel rod and M20x1.5 thread to handle high side loads, while the extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-30S Is Used
Machine Setup & Changeover
Dial in the exact 445 to 475mm end-position during product size changeovers on automated lines without swapping out the entire cylinder.
Variable End-Stop Tuning
Use the 30mm rear adjustment screw to fine-tune the retract position during commissioning, absorbing mechanical tolerances directly at the cylinder.
Heavy-Duty Positioning
Leverage the 3927N push force at 0.5 MPa to move heavy pallets or workpieces, relying on the 25mm rod to maintain stability under load.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-30S the Right Cylinder?
Choose this 100mm bore when an application requires substantial thrust, such as 3927N push at 0.5 MPa, stepping up from a 80mm bore that provides 2513N. The 30mm rear adjuster is selected when machinery requires variable end-stops or precise fine-tuning at setup, rather than relying on a fixed-stroke SAI cylinder. For any stroke of 475mm, always use an external guide to prevent rod side-loading and premature seal wear.
This cylinder is dimensionally interchangeable per ISO 15552. To match this configuration, specify a 100mm bore, 475mm stroke, 30mm adjustment, PT tapered ports, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series.
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 SAIJ100X475-30S FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. If higher pressure is available, it can deliver up to 5497N push force at 0.7 MPa.
The rear adjuster acts as an external stopper that lets you shorten the 475mm nominal stroke by up to 30mm, giving a usable travel window of 445-475mm. It sets the end position but does not lock the load without live air pressure.
