About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-75
The AirTAC SAIJ200X650-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, while its built-in stopper allows you to fine-tune the effective travel down to a 575-650mm window during commissioning. The SUS304 stainless steel rod provides excellent corrosion resistance for harsh environments.
Unlike a fixed-stroke SAI, this model lets you dial in the exact retract position on product changeovers without swapping the barrel or adding external stops. The extruded aluminum profile includes sensor grooves on both sides, though you will need to specify a magnet separately if you plan to use CMSE reed or DMSE electronic sensors.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-75 Is Used
Heavy Press Fine-Tuning
Dial in the exact 575-650mm end position during machine setup to accommodate varying material thicknesses without installing physical spacers.
Product Line Changeover
Quickly adjust the retract stop for different product sizes on a heavy-duty conveyor line, saving changeover time.
Large Assembly Positioning
Securely move large fabricated components into place, relying on the 28274N push force at 0.9 MPa to seat heavy parts.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-75 the Right Cylinder?
Choose this 200mm bore when you need extreme force (up to 3204 kgf at 1.0 MPa) that smaller bores cannot provide; stepping down to a 160mm bore drops your 0.5 MPa push force to 10053N. The 75mm adjustment window is perfect for variable end-stops, but remember the adjuster acts only as a travel stop, not a lock, so it will not hold the load without live air pressure. For load-holding, consider an external rod lock or the SAIL/BSAI series.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints. This specific SKU features a PT tapered G3/4 port and the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 650mm stroke is long and unsupported, you must use an external guide to prevent excessive side-loading on the M36x2 rod thread.
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 SAIJ200BX650-75 FAQ
At 0.7 MPa it provides 21991N of push force, and at 0.9 MPa it delivers 28274N. The maximum push force is 3204 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 650mm nominal stroke by up to 75mm, creating a 575-650mm usable travel window. It only sets the end position and does not lock the load without air pressure.
