About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-50
The AirTAC SAIJ200X100-50 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stopper that allows you to fine-tune the travel end during commissioning. It provides a usable stroke window of 50 to 100 mm, letting you dial back the nominal 100 mm travel by up to 50 mm without adding external stops. As the largest bore in the series, it generates 15708 N of push force at 0.5 MPa and 21991 N at 0.7 MPa.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads sized at G3/4. It carries a 50 mm cushion length to absorb heavy kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, so adding CMSE or DMSE solid-state switches requires a different configuration.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-50 Is Used
Heavy Press Tuning
Dial in the exact 50 to 100 mm end position for heavy pressing operations without swapping out the entire cylinder.
Product Changeover
Quickly adjust the rear stopper to accommodate different product sizes on a high-thrust production line.
Assembly End-Stops
Set precise mechanical travel limits during machine commissioning to prevent over-travel in heavy-duty assembly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-50 the Right Cylinder?
Select this 200 mm bore when your application requires extreme thrust, such as 21991 N at 0.7 MPa, and you need the flexibility to adjust the end position on the fly. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. Choose this adjustable-stroke model over a fixed SAI cylinder when you need precise end-position tuning during machine setup or product-size changeovers. Because the stroke is 100 mm, side-loading is minimal, but always guide the load externally for stability.
This cylinder is dimensionally interchangeable per ISO 15552 mounting interfaces. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. For load-holding without pressure, consider an external rod lock, or use SAIL and BSAI cylinders. Operating speed is 30-500 mm/s.
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 SAIJ200BX100-50 FAQ
It features a rear adjusting screw that lets you shorten the 100 mm nominal stroke by up to 50 mm, providing a usable travel window of 50 to 100 mm. The adjuster acts purely as a mechanical stop and does not lock the load without live air pressure.
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa the push force increases to 21991 N.
