About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-10
The AirTAC SAIJ200X210-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 200 to 210 mm, letting you dial back the nominal stroke by up to 10 mm during commissioning without needing external stops. Built with a robust 40 mm diameter piston rod, it delivers a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa.
This heavy-duty actuator features a SUS420J2 stainless steel rod (code A) for enhanced durability against moisture and minor corrosion, paired with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-10 Is Used
Heavy Press Tuning
Allows precise 10 mm rear adjustment for heavy-duty pressing operations, ensuring exact end-position clamping without adding external mechanical stops.
Product Changeover
Ideal for assembly lines handling varying product sizes, enabling operators to quickly dial in the 200-210 mm stroke window during format changeovers.
Machine Setup
Simplifies final commissioning on large machinery by letting technicians fine-tune the retract stroke endpoint mechanically rather than repositioning the entire cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-10 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires massive thrust—up to 15708 N at 0.5 MPa—along with precise end-position tuning. If your force requirements are lower, stepping down to a 160 mm bore provides 10053 N of push force at 0.5 MPa, which may offer a more compact and efficient solution. The SAIJ200X210-10 is selected specifically when you need a 200 to 210 mm adjustable travel window to accommodate product-size changes on a line without swapping the entire cylinder.
For a drop-in ISO 15552 replacement, match the 200 mm bore, 210 mm nominal stroke, 10 mm adjustment, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 210 mm stroke is relatively short for this bore, side-load concerns are minimal, but an external guide is still recommended for heavy loads. Note that this plain cylinder does not hold position unpowered; for load-holding without live air, consider an AirTAC SAIL or BSAI series.
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 SAIJ200AX210-10 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 210 mm nominal stroke down to 200 mm. It sets the retract end position for fine-tuning but does not lock or hold the load without continuous air pressure.
