About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX20-20
The AirTAC SAIJ200X20-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a massive 28274N of push force at 0.9 MPa. It features an external rear adjusting screw that allows you to fine-tune the effective stroke within a 0 to 20 mm usable travel window, providing exact end-position control without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This specific SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a PT tapered port thread. Unlike a fixed-stroke SAI cylinder, this adjustable variant is designed for commissioning flexibility. The rear adjuster acts strictly as a mechanical stop to set the travel end and does not hold the load without live air pressure. For load-holding requirements without continuous pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX20-20 Is Used
Heavy Pressing Operations
Ideal for high-force pressing and clamping where the 0-20 mm travel window must be dialed in precisely to avoid over-travel during machine setup.
End-Stop Calibration
Perfect for applications requiring variable end-stops, allowing operators to fine-tune the retraction point during product changeovers without swapping cylinders.
Corrosive Assembly Lines
The SUS304 stainless steel rod provides the necessary corrosion resistance for heavy industrial assembly lines operating in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX20-20 the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme thrust—up to 3204 kgf at 1.0 MPa—and requires exact end-position tuning within a short 0-20 mm travel window. If your setup only needs standard fixed positioning without the rear adjuster, the base SAI series is a simpler alternative. Because the stroke is short (20 mm), side-load stress on the 40 mm rod is minimized, though the robust M36x2 rod thread ensures high structural integrity.
When specifying an ISO 15552 replacement, match the 200 mm bore, 20 mm nominal stroke, PT port, and SUS304 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts. Since no magnet is specified (-S omitted), position sensing via CMSE or DMSE sensors is not supported on this specific configuration.

- ✓ 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 SAIJ200BX20-20 FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder generates a push force of 28274N and a pull force of 15080N. The maximum thrust capacity is 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 20 mm nominal stroke anywhere within a 0 to 20 mm usable travel window. It only sets the travel end and does not lock or hold the load without continuous air pressure.
