About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-10
The AirTAC SAIJ200X280-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 15708N push force at 0.5 MPa and features a 270-280mm usable travel window, letting you dial back the nominal 280mm stroke by up to 10mm. This built-in adjustability allows precise end-position tuning at commissioning without adding external stops or swapping the cylinder.
This heavy-duty actuator utilizes a SUS420J2 stainless steel piston rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. While the rear screw sets the travel end, remember it acts as a stop rather than a lock; the SAIJ does not hold loads without live air pressure, so pilot-operated check valves or a BSAI clamp-lock are needed for secure load holding.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-10 Is Used
Heavy Press Tuning
Fine-tune the 270-280mm travel window on a high-force press to perfectly mate parts without over-stroking the 200mm bore cylinder.
Product Changeover Stops
Quickly adjust the end-stop position by up to 10mm during line changeovers to accommodate different product sizes on the fly.
Large Assembly Calibration
Dial in the exact retract position during machine commissioning, leveraging the 15708N thrust for heavy automotive or industrial assembly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-10 the Right Cylinder?
Choose this 200mm bore actuator when your application requires maximum thrust in the SAIJ range, delivering 15708N push and 15080N pull at 0.5 MPa. If your force requirements are lower, stepping down to a 160mm bore yields 10053N push force, saving space and air consumption. The adjustable-stroke design is ideal for machine setups requiring variable end-stops during product changeovers, whereas a fixed-stroke SAI is simpler for dedicated tasks.
When replacing an ISO 15552 cylinder, match the 200mm bore, 280mm stroke, 10mm adjustment, PT ports, and your required mounting accessory from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this is a 280mm stroke, ensure adequate external guidance to handle side loads and prevent rod bending over the extended travel.
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 SAIJ200AX280-10 FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can deliver up to 21991N push force at 0.7 MPa.
A rear adjusting screw lets you shorten the effective travel from the nominal 280mm down to 270mm. This creates a 270-280mm usable window for precise end-position tuning without swapping the cylinder.
