About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-50S
The AirTAC SAIJ80X200-50-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down by up to 50 mm. This yields a usable stroke window of 150-200 mm, letting you dial in the exact retract end-position at commissioning without adding external stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides. It uses a PT G3/8 port and offers a reduced mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) compared to fixed SAI types, omitting FB, CA, CB and CR options.

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 SAIJ80BX200-50S Is Used
Machine Changeover
Quickly adjust the 150-200 mm travel window during product size transitions without disassembling the cylinder or adding external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-50S the Right Cylinder?
The 50 mm adjustable range is perfect for product-size changeovers on a line, allowing operators to reposition the retract stop quickly. For a fixed end-position without the need for commissioning tweaks, a standard SAI cylinder is sufficient.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 200 mm nominal stroke, 50 mm adjustment, PT G3/8 port, and SUS304 rod material. Note that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold a load without live air pressure. For load-holding without compressed air, consider the SAIL or BSAI series. At 200 mm stroke, side-loading is moderate, but always ensure proper external guiding for heavy offset loads.
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 SAIJ80BX200-50S FAQ
At 0.9 MPa, the push force increases to 4523 N.
A rear external stopper screw lets you trim the nominal 200 mm stroke back by up to 50 mm, creating a usable travel window of 150-200 mm. The adjuster is a mechanical stop, not a lock, so it cannot hold the load without live air pressure.
