About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-75S
The AirTAC SAIJ100X800-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for exact position detection.
This model uses a SUS304 stainless steel rod (code B) for superior corrosion resistance and carries a robust M20x1.5 rod thread. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without swapping components; it does not lock the load. For applications requiring position holding without live air pressure, an external pilot-operated check valve or the related SAIL lock cylinder is required.

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 SAIJ100BX800-75S Is Used
Variable Product Changeover
Dial in the 725-800 mm travel window during format size changes on a packaging line, using the rear screw to set exact retract positions without changing the cylinder.
Machine Setup Tuning
Fine-tune the end stop during initial machine commissioning to perfect the timing of an 800 mm cycle, relying on DMSE electronic sensors for high-speed feedback.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-75S the Right Cylinder?
If 3927 N at 0.5 MPa is excessive, stepping down to an 80 mm bore yields 2513 N; if more power is needed, a 125 mm bore provides 6136 N. The adjustable 725-800 mm window is ideal for product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder. When replacing an ISO 15552 unit, match the 100 mm bore, 800 mm stroke, G1/2 port, and mounting style.
Because the stroke is 800 mm, the M20x1.5 rod and piston assembly will experience amplified leverage on the front cap. An external guide rail must be used to prevent excessive side-loading and premature seal wear. Remember that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some standard profiles.
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 SAIJ100BX800-75S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 75 mm, providing a usable travel window of 725 to 800 mm. It sets the end position but does not hold the load without continuous air pressure.
