About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX400-100S
The AirTAC SAIJ80X400-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 400 mm travel back by up to 100 mm, creating a precise 300-400 mm usable window.
This adjustable-stroke design allows you to fine-tune end positions at commissioning or during product changeovers without swapping the cylinder or adding external stops. The rear mechanism acts purely as a travel stop for the retract end and does not hold the load without live air pressure. For load-holding without continuous supply, consider an external rod lock or the AirTAC 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 SAIJ80BX400-100S Is Used
Changeover Tuning
Dial in the retract end-position from 300 to 400 mm during product size changeovers without disassembling the machine or adding external stop blocks.
Commissioning Calibration
Fine-tune the final resting position during initial machine setup, absorbing mechanical tolerances by trimming up to 100 mm off the nominal stroke.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX400-100S the Right Cylinder?
The 25 mm rod diameter and M20x1.5 thread provide robust resistance to side loads, but at 400 mm of travel, an external guide is recommended to prevent rod binding.
An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for machine setup. To match this ISO 15552 replacement exactly, specify: 80 mm bore, 400 mm nominal stroke, 100 mm adjustment, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet for CMSE reed or DMSE electronic sensors.
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 SAIJ80BX400-100S FAQ
It reaches a maximum of 513 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the 400 mm nominal stroke by up to 100 mm, giving a usable travel window of 300-400 mm. It only sets the end position and does not lock the load without live air.
