About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X250-30S
The AirTAC SAIJ200X250-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. The built-in -30mm adjustment screw creates a precise 220-250mm usable travel window, allowing you to dial in the exact retract end-position without adding external stops. A -S magnet is included for position sensing.
This bore features a robust 40mm carbon steel rod and a G3/4 PT tapered port to handle high airflow demands. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. You can pair the magnet with AirTAC CMSE reed or DMSE electronic sensors to track carriage movement accurately across the adjusted travel range.

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 SAIJ200X250-30S Is Used
Heavy Press Tuning
Fine-tune the 220-250mm travel window during machine commissioning to set precise pressing depths on large industrial assemblies without swapping cylinders.
Large Mold Handling
Position and seat heavy molds accurately by dialing back the stroke up to 30mm, ensuring safe alignment before the final clamping operation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X250-30S the Right Cylinder?
The adjustable 220-250mm stroke window is perfect for heavy product changeovers, letting you fine-tune the end stop at commissioning rather than machining new hard stops. Because the 250mm stroke is below the 300mm side-load threshold, standard mounting is less critical, but the substantial 40mm rod still handles incidental side loads well.
When specifying a replacement, match the 200mm bore, 250mm nominal stroke, -30mm adjuster, G3/4 PT ports, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking without pressure, consider the SAIL or BSAI series instead.
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 SAIJ200X250-30S FAQ
The rear adjuster screw lets you shorten the 250mm nominal stroke by up to 30mm, creating a 220-250mm usable travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
