About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX50-10S
The AirTAC SAIJ100X50-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 40 to 50 mm, allowing you to dial back the nominal 50 mm stroke by up to 10 mm during commissioning. Equipped with a SUS304 stainless steel rod and a PT tapered port thread, it delivers a robust 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa.
This model includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. The 25 mm rod and M20x1.5 thread provide high rigidity, while the rear adjuster acts purely as a mechanical stop to fine-tune the end position without needing external bumpers.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX50-10S Is Used
Machine Setup Tuning
Dial in the exact 40 to 50 mm travel window during initial commissioning to perfect end-of-stroke positioning without machining new stop blocks.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate different package sizes on a packaging line, reducing downtime between runs.
High-Force Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy jigs into place, using the fine stroke adjustment to prevent hard impacts at the end of travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX50-10S the Right Cylinder?
Choose this 100 mm bore when your application requires significantly more thrust than the 80 mm bore (which provides 2513 N push at 0.5 MPa), but without stepping up to the heavier 125 mm class. The adjustable stroke is ideal for product changeovers on a line, letting you set variable end stops on the fly rather than swapping out a fixed-stroke SAI cylinder.
For any load-holding requirements, remember that this SAIJ model does not lock the load without live air pressure—the rear adjuster is a travel stop, not a brake. For secure load holding, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets. Because the stroke is under 300 mm, standard mounting provides sufficient support without an external guide.
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 SAIJ100 Adjustable Cylinder SAIJ100BX50-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The nominal stroke is 50 mm, but the rear adjusting screw allows you to shorten the effective travel by up to 10 mm, creating a usable stroke window of 40 to 50 mm for fine-tuning end positions.
