About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-40S
The AirTAC SAIJ100X270-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 230 to 270 mm.
This model features PT tapered port threads (G1/2) and variable air cushions at both ends to manage kinetic energy. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock the load, meaning continuous air pressure is required to hold position.

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 SAIJ100BX270-40S Is Used
Product Changeovers
Dial in the 230-270 mm travel window during format changes to accommodate different product sizes without replacing hardware.
Machine Setup
Use the rear mechanical stop to precisely set end-of-stroke positions during initial machine commissioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-40S the Right Cylinder?
The 40 mm adjustment range is ideal for product changeovers on a line, allowing you to shift the end-stop without swapping out the entire cylinder or adding external stops. For load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 270 mm stroke, 40 mm adjustment, PT port threads, and the -S magnet requirement. Because the 270 mm stroke is moderately long, ensure external guiding is used to prevent excessive side-loading on the SUS304 rod. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX270-40S FAQ
The rear adjuster allows you to mechanically shorten the nominal 270 mm stroke by up to 40 mm, creating a usable travel window of 230 to 270 mm. It acts as a travel stop and does not lock the load without air pressure.
