About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX250-100
The AirTAC SAIJ100X250-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 250mm stroke that can be mechanically dialed back by up to 100mm, giving operators a flexible 150-250mm usable travel window for precise end-position tuning during commissioning.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in humid or washdown settings, alongside PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this unit ships without a magnet. The rear adjuster acts purely as a mechanical stop to set the retract endpoint and does not lock the load without live air pressure.

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 SAIJ100BX250-100 Is Used
Variable End-Stop Machining
Dial in the exact clamping depth across a 150-250mm window during machine setup, allowing rapid changeover for different part lengths without swapping cylinders.
Product Size Changeover
Quickly adjust the retract position on packaging lines handling varying box sizes, using the 100mm rear stopper to fine-tune the travel endpoint at commissioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX250-100 the Right Cylinder?
The 100mm adjustment range is ideal for machinery that frequently processes different product sizes, allowing you to shorten the stroke from 250mm down to 150mm without adding external stops or changing the cylinder. If your setup demands less force, stepping down to an 80mm bore yields 2513N at 0.5MPa; if you need more, a 125mm bore offers 6136N at 0.5MPa.
Because this SKU lacks a magnet, position sensing via CMSE or DMSE switches is not possible without modification. For load-holding requirements without continuous air pressure, note that this cylinder's rear stop and air cushions do not function as a brake—consider an AirTAC SAIL or BSAI series instead. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, strictly omitting FB, CA, CB, and CR options to maintain the profile-body geometry.
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 SAIJ100BX250-100 FAQ
At the maximum operating pressure of 0.9MPa, the push force increases to 7068N.
The rear adjuster screw allows you to shorten the effective travel from the 250mm nominal stroke by up to 100mm. This creates a usable travel window of 150-250mm, enabling fine end-position tuning without external stops.
