About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-75S
The AirTAC SAIJ200X325-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa. The built-in rear stopper screw provides a 250-325mm usable travel window, letting you dial back the 325mm nominal stroke by up to 75mm. This fine-tuning happens directly at commissioning without swapping cylinders or adding external stops.
This 200mm bore unit features a carbon steel rod and a PT tapered G3/4 port. Because it includes the -S magnet, it works seamlessly with AirTAC CMSE reed and DMSE electronic sensors in the dual sensor grooves. The rear adjuster acts purely as a travel stop and works with the variable air cushions to decelerate the load, but it 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 SAIJ200X325-75S Is Used
Heavy Press Tuning
Fine-tune the 250-325mm travel window during machine setup to precisely dial in heavy pressing operations without changing the cylinder.
Product Size Changeover
Quickly adapt the end-stop position on a conveyor line when product dimensions change, using the 75mm rear adjuster instead of reworking fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-75S the Right Cylinder?
If you need less force, stepping down to the 160mm bore yields 10053N, while the 125mm bore provides 6136N. The adjustable 250-325mm window is perfect for product changeovers on a line, allowing variable end-stops without mechanical rebuilds. For load-holding without live pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is not a brake.
This SKU is dimensionally interchangeable per ISO 15552. Configuration: 200mm bore, 325mm stroke, 75mm adjustment, PT G3/4 port, carbon steel rod, -S magnet for CMSE/DMSE sensors. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 325mm stroke is long, the 40mm rod and M36x2 thread can carry significant side load, but an external guide rail is still recommended for unsupported lengths.
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 SAIJ200X325-75S FAQ
The rear adjuster screw lets you shorten the effective travel from the 325mm nominal stroke by up to 75mm, providing a usable 250-325mm window. It acts as a mechanical stop to set the end position and is not a lock.
At the maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
