About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-75
The AirTAC SAIJ100X650-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 575 to 650 mm.
The integrated rear stopper allows you to fine-tune the retract end position during commissioning without adding external stops. It supports AirTAC CMSE reed and DMSE electronic sensors via dual-side barrel grooves, and utilizes a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100BX650-75 Is Used
Variable End-Stop Positioning
Dial in the retract distance from 575 to 650 mm during machine commissioning to accommodate varying material lengths without disassembling the pneumatic circuit.
Heavy Load Deceleration Tuning
Fine-tune the end-of-stroke position alongside the adjustable air cushions to smoothly decelerate substantial masses over the 650 mm travel path.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-75 the Right Cylinder?
Select this 100 mm bore cylinder when an application requires heavy thrust (up to 801 kgf at 1.0 MPa) alongside precise end-position tuning, stepping up from a 63 mm bore that yields 2805 N at 0.9 MPa. Because the 650 mm stroke is substantial, an external guide is strongly recommended to manage side loads and prevent rod binding.
The rear adjuster acts strictly as a travel stop, not a lock, meaning it cannot hold a load without live air pressure. For drop-prevention or dead-air holding, consider an AirTAC SAIL or BSAI variant. To match this exact configuration for an ISO 15552 replacement, verify the 100 mm bore, 650 mm nominal stroke, 75 mm adjustment, PT ports, SUS304 rod, and the absence of a magnet.
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 SAIJ100BX650-75 FAQ
The rear adjuster screw acts as an external stopper that shortens the effective stroke by up to 75 mm, providing a usable travel window of 575 to 650 mm. This allows precise end-position tuning at commissioning without swapping the cylinder.
It can deliver a maximum push force of 801 kgf at 1.0 MPa.
