About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-10S
The AirTAC SAIJ100X210-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 200 to 210 mm usable travel window, allowing you to dial in the retract end-position precisely during commissioning. Built with a SUS304 stainless steel rod and a PT tapered port thread, it delivers 3927 N of push force at 0.5 MPa and integrates seamlessly with existing mounting footprints.
This adjustable-stroke model uses an external stopper screw to set the travel limit rather than relying on internal spacers. The extruded aluminum barrel features sensor grooves on both sides, and because this SKU includes the -S magnet option, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors for precise position feedback.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-10S Is Used
Product Changeover Adjustment
Quickly tune the 10 mm retract window to accommodate varying product lengths on an assembly line without changing out the entire actuator.
Machine Setup Calibration
Dial in the exact end-of-stroke position during commissioning to perfectly time press or clamping operations within a 200 to 210 mm range.
Stainless Rod Equipment
Leverage the SUS304 rod and 3927 N thrust for robust pushing tasks in environments where standard carbon steel rods might face corrosion issues.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX210-10S the Right Cylinder?
Choose this 100 mm bore actuator when your application requires 3927 N push force at 0.5 MPa (or 7068 N at 0.9 MPa) alongside fine-tuneable end positioning. If your setup demands less force, stepping down to an 80 mm bore yields 2513 N push force at 0.5 MPa. Conversely, heavier loads may require the 125 mm bore which provides 6136 N. The 10 mm adjustment window is ideal for accommodating minor product size changes on a production line without physically swapping the cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 210 mm stroke, 10 mm adjustment, PT port thread, and -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series. For this 210 mm stroke, ensure external guidance is used to prevent excessive side-load wear on the rod.
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 SAIJ100BX210-10S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 200 to 210 mm usable travel window. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
