About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-75S
The AirTAC SAIJ200X220-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This yields a usable stroke window of 145 to 220 mm, giving you precise control over the end position without swapping out the barrel. As the largest bore in the series, it delivers immense thrust, pushing 21991 N at 0.7 MPa and reaching 28274 N at 0.9 MPa.
This specific SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic solid-state sensors. It uses a G3/4 PT tapered port and operates at speeds of 30 to 500 mm/s. The extruded aluminum barrel incorporates sensor grooves on both sides, and the adjustable stopper functions purely as a travel end-deceleration point, not a lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-75S Is Used
Heavy Press Tuning
Dial in the exact 145 to 220 mm travel window during heavy press commissioning to accommodate material thickness variations without replacing the cylinder.
Product Changeover Stops
Adjust the retract end-position on the fly for different package sizes moving down a heavy-duty conveyor line, saving time on machine setup.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and 28274 N of output force to execute heavy assembly pushes in washdown or mildly corrosive factory environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-75S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires massive force that smaller neighbors cannot provide; for context, stepping down to a 160 mm bore drops your 0.5 MPa push force from 15708 N to 10053 N. You would choose this adjustable SAIJ over a fixed-stroke SAI when a machine requires fine end-position tuning during commissioning or frequent product-size changeovers, allowing you to dial in the 145 to 220 mm travel window without bolting on external stops.
Because the nominal stroke is 220 mm, you do not need external side-load guidance for purely axial loads, but long unsupported heavy loads still require a guide. If your machine needs to hold the load in place without live air pressure, this cylinder's adjuster will not act as a brake; you must look to the SAIL (air-released lock) or BSAI (clamp-lock) series instead. This SAIJ model is dimensionally interchangeable per ISO 15552 mounting-interface dimensions, uses a G3/4 PT port, and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200BX220-75S FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder generates a maximum push force of 28274 N. At 0.7 MPa it provides 21991 N of push force.
The rear adjuster screw allows you to shorten the 220 mm nominal stroke by up to 75 mm, creating a usable travel window of 145 to 220 mm. This stopper only sets the travel end and decelerates the load; it does not lock or hold the load without live air pressure.
