About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-100S
The AirTAC SAIJ80X500-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 500 mm travel by up to 100 mm for a precise 400-500 mm usable window.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, utilizing the standard extruded aluminum barrel with sensor grooves on both sides. The rear stopper acts purely as a travel end-point tuner for product changeovers, not a load lock, meaning live air is required to hold position. It supports a speed range of 30-800 mm/s and features PT tapered ports sized at G3/8.

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 SAIJ80BX500-100S Is Used
Variable Length Machining
Fine-tune the 400-500 mm stroke window on the fly to accommodate different material lengths during production changeovers without external stops.
Product Diversion Setup
Adjust the retract position precisely during commissioning to align pusher arms with varying package sizes on a packaging line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-100S the Right Cylinder?
The 100 mm adjustment window is ideal for machinery processing varying product lengths, letting you fine-tune the retract end-position without swapping hardware. Because the nominal stroke is 500 mm, an external guide is recommended to prevent excessive side-loading on the rod.
For an exact ISO 15552 replacement, match the 80 mm bore, 500 mm stroke, 100 mm adjuster, PT G3/8 ports, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your application requires holding the load without continuous air pressure, use an external rod lock or pilot-operated check valve, as the SAIJ adjuster and air cushions do not function as brakes.
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 SAIJ80BX500-100S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm from the nominal 500 mm, providing a usable travel window of 400 to 500 mm. This stopper only sets the end position and does not lock the load without live air.
