About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX450-10S
The AirTAC SAIJ80X450-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 440 to 450 mm, allowing you to dial back the nominal 450 mm stroke by up to 10 mm during commissioning without adding external stops.
This adjustable-stroke design uses the rear screw purely as a mechanical stop to set the end position, meaning it will not hold a load if air pressure drops. For true fail-safe load holding, you would need an external pilot-operated check valve or a related AirTAC series like SAIL or BSAI. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet works seamlessly with AirTAC CMSE reed switches and DMSE solid-state electronic sensors.

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 SAIJ80BX450-10S Is Used
Machine Commissioning
Dial in the exact end-of-stroke position within a 440-450 mm window during initial machine setup without physically swapping out cylinders.
Product Changeover
Quickly adjust the stroke by a few millimeters on a packaging line when switching to a slightly different product size.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX450-10S the Right Cylinder?
The 10 mm adjustment range is ideal for fine-tuning end-of-stroke positions during machine setup or product changeover, offering flexibility that a fixed-stroke SAI cylinder cannot match. It uses a PT (tapered) G3/8 port and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
Because this model has a 450 mm stroke, the 25 mm diameter rod and M20x1.5 thread provide good structural rigidity, but an external guide rail is still recommended to prevent excessive side-loading on the piston rod over long unsupported travels. The cylinder operates at speeds between 30 and 800 mm/s and features variable air cushions at both ends to manage deceleration.
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 SAIJ80BX450-10S FAQ
The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 450 mm down to as little as 440 mm. It only sets the travel end and does not lock the load without live air pressure.
