Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-50S
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX65-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 65mm 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 SAIJ100BX65-50S
Its 65mm nominal stroke can be dialed back by up to 50mm, providing an exact 15-65mm usable travel window. This built-in adjustability allows you to fine-tune the retract end position during commissioning without adding external stops.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT G1/2 port ensures high flow for the 100mm bore. The rear adjusting screw acts purely as a travel stop and does not hold the load without live air.

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 SAIJ100BX65-50S Is Used
Machine Changeover
Dial in the 15-65mm travel window during product size transitions to set new retract positions without replacing hardware.
End-Stop Calibration
Fine-tune the final retract position at commissioning using the rear screw, ensuring precise mechanical alignment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-50S the Right Cylinder?
An adjustable stroke is ideal for machine setups requiring variable end-stops or frequent product-size changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. For a true ISO 15552 replacement match, verify the 65mm stroke, 50mm adjustment, PT G1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Because the stroke is under 300mm, side-load stress is minimized, though the robust 25mm rod still handles standard loads well. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100BX65-50S FAQ
The rear adjuster lets you shorten the 65mm nominal stroke by up to 50mm, creating a 15-65mm usable travel window. It acts as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At 0.7MPa the push force increases to 5497N.
