About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-20S
The AirTAC SAIJ100X750-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. With a 750 mm nominal stroke and a 20 mm adjustment screw, it provides a usable travel window of 730-750 mm, letting you dial in the exact end-stop during commissioning without adding external stops. It delivers robust thrust, pushing 7068 N at 0.9 MPa.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.

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 SAIJ100BX750-20S Is Used
Product Changeover
Fine-tune the 730-750 mm travel window during machine setup to accommodate slightly different product lengths without changing the cylinder.
Long-Stroke Diverting
Actuate large diverters or gates over a 750 mm distance, using the adjustable stop to perfectly time the end position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-20S the Right Cylinder?
An adjustable stroke is ideal for product-size changeovers on a line, allowing you to shorten the travel by up to 20 mm on the fly rather than swapping to a fixed-length SAI cylinder. Because the 750 mm stroke is long, ensure you use an external guide to support the load and prevent excessive side-loading on the rod.
When matching an ISO 15552 replacement, verify the 100 mm bore, 750 mm stroke, 20 mm adjustment range, PT port thread, and the -S magnet. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold its load without live air. For positive load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder, or use an external pilot-operated check valve.
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 SAIJ100BX750-20S FAQ
At 0.5 MPa, the push force is 3927 N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20 mm. This creates a 730-750 mm usable travel window, allowing you to trim the retract position during commissioning without replacing the cylinder.
