About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-100
The AirTAC SAIJ80X105-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 105 mm travel back by up to 100 mm. This yields a highly versatile 5 to 105 mm usable travel window, perfect for prototyping or lines running multiple product sizes. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh or washdown environments. It uses PT tapered port threads and lacks a piston magnet. Remember that the rear adjuster acts only as a mechanical stop to set the end position; it does not lock the load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI series.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX105-100 Is Used
Product Changeover
Rapidly adjust the end-of-stroke stop from 5 mm to 105 mm to accommodate varying package sizes on a single conveyor line without changing tooling.
Prototyping Fixtures
Dial in the exact clamping distance during R&D commissioning, finding the optimal travel window before finalizing a fixed-stroke SAI cylinder design.
Washdown Clamping
Leverage the SUS304 stainless steel rod for corrosion resistance while providing 2513 N of pull force at 0.5 MPa in food processing or chemical handling stations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-100 the Right Cylinder?
The massive 100 mm adjustment range is ideal for machine changeovers, letting you dial in the exact end-stop without swapping cylinders or adding external stops. If your application requires position feedback, note that this specific SKU lacks the -S magnet, so CMSE reed or DMSE electronic sensors will not function. You would need the -S variant for that.
When replacing an ISO 15552 cylinder, match these exact specs: 80 mm bore, 105 mm stroke, 100 mm adjustment, PT port threads, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the nominal stroke is 105 mm, side-load risks are minimal, but always ensure the M20x1.5 rod thread is securely coupled to your load to prevent misalignment.
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 SAIJ80 Adjustable Cylinder SAIJ80BX105-100 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its nominal 105 mm down to as little as 5 mm. This creates a 5-105 mm travel window. Note that this adjuster only sets the end position; it does not function as a lock to hold the load without continuous air pressure.
At 0.9 MPa, the push force increases to 4523 N.
