About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-75S
The AirTAC SAIJ100X275-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 200 to 275 mm usable travel window, allowing you to dial back the 275 mm nominal stroke by up to 75 mm during commissioning.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and features a built-in magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the unit uses a PT tapered G1/2 port. Mounting options are limited to the standard SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-75S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance for machining or clamping operations without physically replacing the cylinder or adding external mechanical stops.
Product Size Changeover
Quickly adjust the 200-275 mm travel window to accommodate different product lengths on a packaging or sorting line during production transitions.
Commissioning Fine-Tuning
Perfect for dialing in the precise end-position during machine setup, compensating for mechanical tolerances directly at the rear adjustment screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-75S the Right Cylinder?
The adjustable stroke is ideal for product-size changeovers on a line, as the rear stopper fine-tunes the travel end without swapping the cylinder or adding external stops.
Because the nominal stroke is 275 mm, you should ensure adequate side-load support by using an external guide to prevent rod binding over long unsupported travel. Remember that the rear adjuster is a travel stop, not a lock; it will not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI cylinder series. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 275 mm stroke, 75 mm adjustment, PT G1/2 port, and the -S magnet option.
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 SAIJ100BX275-75S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 275 mm nominal stroke by up to 75 mm, creating a usable travel window of 200 to 275 mm. It only sets the end position and does not lock the load without live air pressure.
