About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-100S
The AirTAC SAIJ200X210-100-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It delivers a substantial 15708N of push force at 0.5 MPa and features a rear stroke adjuster that creates a usable travel window of 110-210mm. This allows you to trim the effective stroke by up to 100mm without swapping the cylinder. Equipped with a -S magnet, it supports AirTAC CMSE reed and DMSE electronic sensors.
This model features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air; for position holding without pneumatic pressure, consider an external rod lock or the SAIL/BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-100S Is Used
Heavy Press Tuning
Dial in the exact 110-210mm travel window during setup to apply maximum forming force without over-traveling the tooling.
Product Changeover
Quickly adjust the rear stopper by up to 100mm to accommodate different package sizes on a high-thrust diverting line.
Large Clamp Positioning
Fine-tune the clamping end-position on heavy fixtures at commissioning, using the 15708N thrust to secure large workpieces.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-100S the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme thrust, stepping up from a 160mm bore that provides 10053N push force at 0.5 MPa. The 100mm adjustment range is perfect for product-size changeovers on a line, allowing you to dial in the exact end-stop during commissioning rather than machining custom spacers or buying a fixed-stroke SAI cylinder. Because the 210mm stroke exceeds 300mm is false here, but note that long unsupported strokes still require an external guide to manage side loads.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 200mm bore, 210mm stroke, 100mm adjustment, G3/4 PT port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ200AX210-100S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster acts as a mechanical stop that lets you shorten the 210mm nominal stroke by up to 100mm, creating a usable travel window of 110-210mm. It only sets the travel end and does not lock the load without live air pressure.
