About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-50
The AirTAC SAIJ100X90-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, allowing you to dial back the nominal 90 mm travel by up to 50 mm. This creates a highly versatile 40-90 mm usable stroke window, perfect for dialing in exact end positions during machine commissioning without adding external stops.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ100BX90-50 Is Used
Machine Commissioning
Fine-tune the 40-90 mm travel window during initial setup to achieve exact positioning without machining custom spacers.
Product Changeover
Quickly adjust the end-stop to accommodate varying product sizes on a single line, minimizing downtime between runs.
Variable End-Stop Actuation
Provide adaptable push-off force up to 7068 N at 0.9 MPa for packaging or assembly fixtures requiring flexible stroke lengths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-50 the Right Cylinder?
An adjustable stroke is selected over a fixed SAI when a process requires variable end-stops or frequent product changeovers. To match this ISO 15552 replacement exactly, specify a 100 mm bore, 90 mm stroke, 50 mm adjustment, PT ports, and the SUS304 (B) rod material.
Because the rear adjuster acts only as a travel stop and the air cushions handle deceleration, neither will hold a load without live air pressure. For dead-air load holding, consider an external rod lock or AirTAC SAIL and BSAI series cylinders. While the 25 mm rod and M20x1.5 thread handle high side loads well, any application approaching the 1500 mm max standard stroke requires an external guide to prevent rod binding.
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 SAIJ100BX90-50 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjusting screw acts as a mechanical stop that allows you to trim the effective travel back from the 90 mm nominal stroke down to as little as 40 mm. This provides a 50 mm adjustment window for precise end-position tuning at commissioning.
