About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-75S
The AirTAC SAIJ80X105-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This creates a highly flexible usable travel window from 30 mm to 105 mm, allowing precise end-position tuning without swapping out the physical cylinder.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes the -S magnet, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX105-75S Is Used
Product Size Changeovers
Quickly dial the stroke back from 105 mm down to 30 mm via the rear stopper when a packaging line switches to a different carton size, eliminating the need to physically swap cylinders.
Commissioning End-Position Tuning
Fine-tune the exact extend position during machine setup without adding external shims or stops, using the 75 mm adjustment window to perfectly time the 2513 N impact.
Variable End-Stop Forming
Adjust the mechanical stroke limit on the fly for press or forming applications that require different material depths, relying on the robust 80 mm bore for consistent force.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-75S the Right Cylinder?
The 75 mm adjustment range is exceptionally wide, making this cylinder ideal for prototyping or production lines that frequently handle multiple product sizes, functioning as an external stop that saves the cost of buying several fixed-stroke SAI units.
Because the nominal stroke is 105 mm, an external guide is not strictly required for side loads, but always ensure the M20x1.5 rod thread is properly aligned. The rear screw acts purely as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider the SAIL or BSAI series instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For an exact ISO 15552 replacement, match the 80 mm bore, 105 mm stroke, 75 mm adjust, PT G3/8 port, and -S magnet.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80BX105-75S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 105 mm nominal length, providing a usable travel window of 30 mm to 105 mm. It acts as a mechanical stop to set the end position and is not a locking mechanism.
