About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-20S
The AirTAC SAIJ100X90-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end. With a nominal 90 mm stroke and a 20 mm adjustment range, you get a usable travel window of 70 to 90 mm to perfectly dial in your end position without swapping hardware.
Built for demanding environments, this unit includes a SUS304 stainless steel rod for superior corrosion resistance and carries the -S magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel provides sensor grooves on both sides, and the G1/2 PT tapered ports ensure a tight, leak-free pneumatic connection.

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 SAIJ100BX90-20S Is Used
Machine Setup & Changeover
Dial in the exact 70-90 mm travel end-stop during line changeovers without machining new spacers or replacing the entire cylinder.
Variable End-Position Tuning
Fine-tune the retract end position during commissioning to perfect part ejection or clamping depth on the fly.
Product-Size Adaptation
Quickly adjust the effective stroke to accommodate slightly different product sizes on the same production line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-20S the Right Cylinder?
Choose this 100 mm bore when you need heavy force capacity combined with precise end-position tuning during commissioning or product changeover. The adjustable rear stopper on this SAIJ model is strictly a travel stop, not a lock; it will not hold a load without live air. For true load-holding without continuous pressure, consider an AirTAC SAIL or BSAI cylinder.
This SAIJ100X90-20-S is dimensionally interchangeable per ISO 15552 standards. When replacing a cylinder, match the 100 mm bore, 90 mm nominal stroke, 20 mm adjuster, G1/2 PT ports, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ100BX90-20S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a stopper that lets you shorten the effective stroke from the nominal 90 mm down to 70 mm. It sets the travel end and deceleration, but it is not a lock and will not hold the load without continuous air pressure.
