About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X95-20S
The AirTAC SAIJ200X95-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. Instead of relying on external stops, its integrated screw mechanism allows you to fine-tune the effective travel window down from 95 mm to a minimum of 75 mm during commissioning.
This unit includes a standard magnet (-S) for position sensing with AirTAC CMSE reed and DMSE electronic switches, which seat neatly into the extruded aluminum barrel's dual sensor grooves. The carbon steel rod features an M36x2 thread, and the cylinder uses PT G3/4 tapered ports. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting the FB, CA, CB, and CR options.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 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 SAIJ200 Adjustable Cylinder SAIJ200X95-20S Is Used
Heavy Press Tuning
Dial in the exact 75 to 95 mm end-stop for heavy pressing operations without machining new external stopper blocks during product changeovers.
Sensor-Driven Staging
Use the integrated magnet with DMSE solid-state sensors to confirm staging positions while adjusting the travel window to accommodate varying part sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X95-20S the Right Cylinder?
If you need less force, stepping down to a 160 mm bore provides 10053 N at the same pressure, while retaining the same 30-500 mm/s speed range. The adjustable stroke is chosen when you need precise end-position tuning for product changeovers without physically swapping the cylinder or adding external mechanical stops.
For ISO 15552 replacement matching, ensure your specifications align with a 200 mm bore, 95 mm stroke, up to 20 mm rear adjustment, PT G3/4 ports, and a magnet for CMSE or DMSE sensors. Because the nominal stroke of 95 mm is relatively short for this massive bore, side-loading is less of a concern than with longer strokes, but the load should still be guided to prevent rod binding. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ200 Adjustable Cylinder SAIJ200X95-20S FAQ
The rear adjuster screw acts as an external stopper that lets you shorten the effective stroke from 95 mm down to 75 mm. This creates a 20 mm adjustable travel window, allowing you to fine-tune the end position at commissioning without changing the cylinder.
