About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-100S
The AirTAC SAIJ200X475-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 475 mm nominal travel by up to 100 mm. This yields a usable end-position window of 375-475 mm, letting you fine-tune machine stops at commissioning without swapping hardware. It delivers substantial force, pushing 15708 N and pulling 15080 N at 0.5 MPa, while the SUS304 stainless steel rod provides excellent corrosion resistance for harsh environments.
This SKU features a PT tapered port and includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting. Remember that the rear adjuster acts purely as a mechanical stop to set the travel end; it does not lock the load or hold position without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI variants.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-100S Is Used
Large Assembly Pressing
Fine-tune the 375-475 mm stroke window on the fly to press large components to exact depths without changing the cylinder.
Product Line Changeover
Rear stopper adjustment allows operators to quickly set new end positions when switching product sizes on a conveyor line.
Heavy-Duty Machine Setup
Dial in the exact retracted end-position during commissioning of heavy machinery, avoiding the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-100S the Right Cylinder?
Choose this 200 mm bore when your application requires maximum thrust in the SAIJ range, as stepping down to the 160 mm bore drops the 0.5 MPa push force to 10053 N. The adjustable stroke is selected over a fixed SAI when you need variable end-stops for product size changeovers on a line. Since this cylinder features a 475 mm stroke, the 40 mm diameter rod and M36x2 thread handle high loads, but an external guide rail is still recommended to prevent side-loading damage over long unsupported travels.
To match this ISO 15552 interchangeable cylinder exactly, specify: 200 mm bore, 475 mm stroke, 100 mm adjustment, PT G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found on other series.
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 SAIJ200BX475-100S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder delivers 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can generate up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that can trim the 475 mm nominal stroke back by up to 100 mm, creating a usable travel window of 375-475 mm. It sets the end position but does not lock the load without live air.
