About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-20
The AirTAC SAIJ200X275-20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 255 to 275 mm, allowing you to dial back the nominal 275 mm stroke by up to 20 mm during commissioning without adding external stops. Driven by a G3/4 port, it generates a substantial 15080 N pull force at 0.5 MPa, making it suited to heavy-duty handling.
This model uses a robust 40 mm carbon steel rod with an M36x2 thread, which handles high side loads effectively, though an external guide is still recommended for this 275 mm stroke. It features variable air cushions at both ends (50 mm cushion length) and extruded aluminum dual sensor grooves. The rear adjuster acts purely as a travel stop to fine-tune the retract position, not as a lock.

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 SAIJ200X275-20 Is Used
Heavy Machinery Changeover
Dial in the 255-275 mm stroke window during heavy equipment changeovers to accommodate different large-assembly sizes without swapping the cylinder.
Large Assembly Positioning
Fine-tune the retract end-stop on large fixtures, using the 40 mm rod and M36x2 thread to manage significant side loads during positioning.
Variable End-Stop Tuning
Achieve precise end-position control on heavy press lines by adjusting the rear stopper up to 20 mm, avoiding the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-20 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires up to 15080 N of pull force at 0.5 MPa (or 3204 kgf at 1.0 MPa) and on-the-fly end-position tuning. If your force requirements are lower, stepping down to a 160 mm bore yields 9425 N of pull force at 0.5 MPa, whereas a larger setup would require custom components beyond the 200 mm profile. The adjustable 255-275 mm window is ideal for product changeovers, replacing fixed-stroke SAI cylinders when exact end-stops vary.
Because the SAIJ200X275-20 lacks a magnet (-S), it does not support CMSE or DMSE sensors. The rear adjuster and air cushions decelerate the load but cannot hold it without live air pressure; for fail-safe load holding, consider an SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and uses a PT tapered G3/4 port. It supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and operates at 30-500 mm/s.

- ✓ 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 SAIJ200X275-20 FAQ
The adjustable travel window ranges from 255 to 275 mm, allowing the 275 mm nominal stroke to be trimmed back by up to 20 mm.
The rear screw acts as a mechanical stop that fine-tunes the retract end position during commissioning. It is not a lock or brake; the cylinder will not hold its load without live air pressure. For load-holding, an SAIL or BSAI cylinder is required.
