About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-30
The AirTAC SAIJ200X280-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 250-280 mm usable travel window. This size utilizes a 50 mm variable air cushion at both ends to dissipate high kinetic energy smoothly.
The external adjustment screw lets you fine-tune the retract end-position during commissioning or product changeovers without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. Remember that the rear adjuster acts only as a travel stop and 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 SAIJ200X280-30 Is Used
Heavy Press Tuning
Dial in the exact 250-280 mm travel window during machine setup to accommodate different material thicknesses without adding external mechanical stops.
Large Product Changeover
Quickly reposition the retract end-stop on packaging lines when switching between large pallet sizes, using the 30 mm adjustment range to fine-tune the stroke.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-30 the Right Cylinder?
If your application requires less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, while moving up is impossible within standard ISO 15552 profiles. The adjustable stroke is ideal for machines needing variable end-stops, whereas a fixed SAI cylinder is better for dedicated unchanging cycles.
Because this is a 280 mm stroke, the 40 mm rod will experience significant leverage forces under side-loading; always use an external guide rail to prevent premature seal wear. For load-holding without live air, the SAIJ adjuster cannot act as a brake—consider an AirTAC SAIL or BSAI series instead. This model is dimensionally interchangeable per ISO 15552, configured with PT tapered ports, a carbon steel rod, and no magnet.
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 SAIJ200X280-30 FAQ
At the maximum 1.0 MPa pressure, it delivers 3204 kgf of push force.
The rear adjuster screw acts as a mechanical stop that shortens the nominal 280 mm stroke by up to 30 mm, giving a usable travel window of 250-280 mm. It allows precise end-position tuning at commissioning but does not lock the load without live air pressure.
