About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX290-20
The AirTAC SAIJ200X290-20 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stopper, allowing you to dial back the nominal 290 mm stroke by up to 20 mm. This yields a precise 270-290 mm usable travel window, perfect for dialing in final end positions during commissioning without swapping out hardware. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing via CMSE or DMSE switches is not supported without adding the -S option. The rear adjuster functions strictly as a travel stop to set the retraction end, not as a locking device.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX290-20 Is Used
Heavy Press Tuning
Fine-tune the 270-290 mm retraction end-point on heavy presses during setup, ensuring precise contact without adding external mechanical stops.
Product Size Changeover
Adapt automated heavy-duty machinery to different product heights by simply turning the rear adjuster screw, saving time on line changeovers.
Large Material Handling
Handle substantial loads with 15708 N of push force at 0.5 MPa, using the adjustable stroke to accommodate varying material lengths safely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX290-20 the Right Cylinder?
Choose this 200 mm bore when you need extreme force, as it outputs 15708 N of push force at 0.5 MPa. If your application requires less thrust, stepping down to a 160 mm bore yields 10053 N, while stepping up is impossible as 200 mm is the largest standard size. The adjustable stroke is highly beneficial for heavy machinery requiring variable end-stops during product changeovers, replacing the need for fixed-stroke SAI cylinders and external stops.
Because the stroke is 290 mm, the 40 mm diameter rod and M36x2 thread provide robust support, but an external guide is recommended to prevent excessive side-loading on long travels. To match this exact cylinder for an ISO 15552 replacement, verify the 200 mm bore, 290 mm stroke, 20 mm adjustment range, PT G3/4 port, and the SUS304 rod material. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster will not hold the load.

- ✓ 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 SAIJ200BX290-20 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. At the maximum pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 290 mm nominal stroke by up to 20 mm, creating a 270-290 mm travel window. It only sets the end position and does not lock the load without live air pressure.
