Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-75
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX950-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 950mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-75
It features a 950 mm nominal stroke that can be fine-tuned backward by up to 75 mm, yielding a usable travel window of 875-950 mm. This built-in adjustability allows precise end-position tuning during commissioning without swapping out the entire unit or adding external stops.
This configuration incorporates a SUS304 stainless steel rod (option B) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Because the rear adjuster acts purely as a mechanical stop and does not lock the load, live air pressure must be maintained to hold position; for dead-air load holding, consider the SAIL or BSAI series instead.

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 SAIJ100BX950-75 Is Used
Product Changeover
Dial in the 875-950 mm travel window on the fly to accommodate different product lengths without physically remounting the cylinder.
Machine Setup
Use the 75 mm rear adjustment screw to perfectly tune the retract end-position during initial commissioning, avoiding the need for external shims.
Variable End Stops
Ideal for sorting diverter arms on long conveyors where the exact stopping point of the 950 mm stroke needs occasional field adjustment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-75 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when you need variable end-stops to accommodate product-size changeovers on a line. To match this ISO 15552 replacement exactly, specify: 100 mm bore, 950 mm stroke, 75 mm adjustment, PT G1/2 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet.
With a 950 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread provide robust support, but long unsupported strokes inherently invite deflection. An external guide mechanism is highly recommended to prevent excessive side-loading and premature seal wear.
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 SAIJ100BX950-75 FAQ
At 0.7 MPa, the push force increases to 5497N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 950 mm nominal stroke down to as little as 875 mm. This creates a 75 mm tuning window for precise end-position setup without changing the cylinder.
