About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-20S
The AirTAC SAIJ200X275-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end position during commissioning. It provides a usable travel window of 255 to 275 mm, letting you dial back the nominal stroke by up to 20 mm without adding external stops.
This variant includes a magnetic piston for position sensing and uses a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The robust 40 mm carbon steel rod and M36x2 thread handle high side loads, while the integrated adjustable air cushions at both ends absorb kinetic energy at the end of travel.

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 SAIJ200X275-20S Is Used
Heavy Press Tuning
Dial in the exact 255-275 mm retract position during heavy press setup to accommodate different material thicknesses without external stopper blocks.
Assembly Line Changeover
Quickly adjust end stops for new product sizes on a high-force assembly line, utilizing the 20 mm rear adjustment range to minimize downtime.
Large Fixture Positioning
Position massive 15708 N loads precisely on large automated fixtures, relying on the 40 mm carbon steel rod for structural rigidity.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-20S the Right Cylinder?
Select this 200 mm bore when your application requires extreme thrust that smaller bores cannot provide, such as lifting heavy fixtures. If 15708 N at 0.5 MPa is excessive, stepping down to a 160 mm bore yields 10053 N, offering a more compact footprint and lower air consumption. The adjustable stroke is highly beneficial for product changeovers, allowing you to set variable end stops on the fly instead of physically swapping out a fixed-stroke SAI cylinder.
For any stroke length of 275 mm or more, the extended unsupported rod is susceptible to bending under heavy loads, so an external guide rail is strongly recommended to prevent premature wear. Furthermore, the rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series instead. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ200X275-20S FAQ
At 0.7 MPa, the push force increases to 21991 N. The operational speed range for this 200 mm bore is 30-500 mm/s.
The rear adjuster screw lets you shorten the effective stroke from the 275 mm nominal length by up to 20 mm, giving a usable travel window of 255 to 275 mm. It acts as a mechanical stop for end-position tuning and is not a lock; the cylinder still requires live air to hold its load.
