About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-75
The AirTAC SAIJ200X325-75 is a double-acting ISO 15552 profile cylinder featuring an integrated rear stroke adjuster. The 75 mm adjustment screw allows you to dial back the 325 mm nominal stroke, creating a precise 250-325 mm usable travel window for exact end-position tuning during commissioning.
This model uses a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage heavy kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic solid-state switches. The rear stopper sets the travel end but does not hold the load without live air pressure.

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 SAIJ200X325-75 Is Used
Heavy Press End-Stop Tuning
Dial in the exact 250-325 mm travel window during setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover Adjustment
Quickly retract the rear stopper by up to 75 mm on automated lines when switching between different large product dimensions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-75 the Right Cylinder?
The 75 mm adjustment range is ideal for machinery requiring variable end-stops across different product sizes, avoiding the need to swap cylinders or bolt on external stops. For load-holding without continuous air pressure, select the SAIL or BSAI series instead, as this adjuster is strictly a travel stop, not a lock.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 325 mm stroke, 75 mm adjustment, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 325 mm stroke is substantial, always use an external guide to prevent side-load damage to the 40 mm rod and rod seal.
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 SAIJ200X325-75 FAQ
The rear adjuster screw lets you shorten the 325 mm nominal stroke by up to 75 mm, creating a 250-325 mm travel window. This allows fine-tuning of the end position at commissioning without adding external stops.
