About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-100S
The AirTAC SAIJ200X275-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N at 0.5MPa and pulling 15080N, making it suited for heavy-duty industrial tasks. The built-in -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches.
With a 275mm nominal stroke and a 100mm adjustment range, this model provides a usable travel window of 175-275mm. You can fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel features sensor grooves on both sides, and the carbon steel rod with an M36x2 thread handles high side loads, though long unsupported strokes still require an external guide.

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 SAIJ200X275-100S Is Used
Heavy Press Tuning
Dial in the exact 175-275mm retract distance during heavy press commissioning to accommodate different material thicknesses without external stops.
Product Size Changeover
Adjust the end position on the fly for varying pallet sizes on a conveyor line, utilizing the 100mm travel window for rapid format changes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-100S the Right Cylinder?
If your setup demands less force, stepping down to a 160mm bore provides 10053N, which may suffice for lighter loads. The adjustable stroke is particularly valuable for machines processing varying product sizes, allowing you to dial in the end-stop precisely. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 200mm bore, 275mm nominal stroke, 100mm adjustment, PT tapered port thread, and the -S magnet option. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 275mm, ensure proper external guiding to prevent excessive side-loading on the M36x2 rod thread.
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 SAIJ200X275-100S FAQ
At 0.7MPa, the push force increases to 21991N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm, creating a usable travel window of 175-275mm from the 275mm nominal stroke. It acts as a mechanical stop and does not lock the load without air pressure.
